Dinner Speech Ban Ki-moon – Copyright: DGVN 2014

At the end of January I had the honour of being invited by the United Nations Association of Germany to give a short speech at a dinner with the Secretary-General of the United Nations Ban Ki-moon in Berlin.

Here you can download the script of my speech: Dinner Speech Ban Ki-Moon

Dear Professor Lu Mai, dear Professor Liu Shinjin, ladies and gentlemen,

It is an unusual honour for me to be invited to this keynote address, which I have put it under the title of Resource Productivity.

Fig 1

This title contrasts with the preoccupation with labour productivity during the last 200 years of technological progress. Labour productivity has been the melody of the first Industrial Revolution. It increased twentyfold or more during those 200 years. This has been the basis of prosperity and it is the main theme of China’s stunning economic progress.

During those same 200 years, the world has also seen a systematic decrease of prices of natural resources.

Fig 2

This invited mankind to a wasteful use of those resources. Small wonder, then, that resource productivity was stagnant or even decreasing during much of this time.

Let me submit to you that we cannot continue on this road. It may be wise, chiefly for the industrialized countries to slow down the further increase of labour productivity while forcing the increase of resource productivity.

Forcing resource productivity has become an imperative also for the developing countries that cannot afford a wasteful use scarce resources. Obviously, this consideration was at the roots of planning this conference. The new trend in technological development, namely a strong emphasis on resource productivity, may be triggered by the recent increase of resource prices:

Fig 3

For China in particular, the rising commodity prices were a signal of warning. But then, you have additional reasons to become more resource efficient. It would allow you to simultaneously reduce one major health problem, namely pollution-caused mortality in your industrial agglomerations:

Fig 4

Clearly, air pollution should also be addressed directly by appropriate pollution control measures. These have an additional cost, which however, is far exceeded by the economic benefits for China, according to Stefan Hirschberg et al (2003) of the Swiss Paul Scherrer Institute:

Fig 5

China is going through the standard development with regard to pollution: Countries start poor and clean. Then they industrialize and get rich and dirty. And then they rich enough so that they can afford pollution control and end up rich and clean:

Fig 6

It has been the traditional view of the developing countries that they are too poor to pay for pollution control. As Indira Gandhi said it in 1972 at the first UN Conference on the Human Environment in Stockholm: “Poverty is the biggest polluter”

Fig 7

Indira Gandhi’s slogan went down well not only with the political leaders of developing countries to whom it was a nice excuse for not acting on pollution control, but also for industry in the North that could conveniently say that they needed good profits for the sake of the environment.

The trouble is that today’s biggest environmental problems, biodiversity losses and climate change, are chiefly caused by the rich.

Fig 8

Regarding biodiversity, the biggest problem is habitat losses due to increased land use for agriculture, settlements, mining, energy and transport. You can estimate the acreage that is needed per person for a sustainable supply of all the daily goods and services. This is then the “ecological footprint” according to William Rees and Mathis Wackernagel, caricatured in the next picture:

Fig 9

The ecological footprints of average Chinese people are roughly one hectare. We in Western Europe have footprints four times as large, and in the US and Canada, footprints are even eight times that size. If all 6.3 billion people had US type lifestyles, we would need three to four planets Earth to accommodate all their footprints. This is obviously unsustainable.

The other big problem is global warming. Global temperatures have been rising and falling over the last 160.000 years in close correspondence with CO2 concentrations.

Fig 10
Based on the physics behind this correlation, the Intergovernmental Panel on Climate Change (IPCC) has projected temperatures to rise dramatically during our century:

Fig 11

The consequences could be alarming for water, food security and for biodiversity. You would also have to count with more devastating typhoons and, most dangerous perhaps, with a rising sea water table, indicated by the green line in the next picture.

Fig 12

The difference between high and low water tables is more than 100 metres, which means that coast lines will heavily vary. The next picture shows it for Italy. 20.000 years ago, during the last Ice Age, the Sea was lower and Italy was larger than today. But two million years ago there were no polar ice caps (and also the geological situation was different in the Mediterranean Basin) so that Italy was much smaller:

Fig 13

At present, we see a dramatic change of temperatures in the Arctic region, as has been discussed in the Arctic Climate Impact Assessment (2004). The summer freshwater coverage of Greenland has increased more than fourfold in ten years:

Fig 14

We are unable to predict the consequences of this development. But we know from historical records that ice masses can collapse or glide into the oceans in a very short period of time. This has been the case with the ice shield once covering Labrador and the Hudson Bay, which disintegrated during a few decades, perhaps even a few weeks some 7800 years ago, letting the sea water table rise by some 7 metres:

Fig 15

Imagine what such a mega-event would mean for China’s or Japan’s coastal areas, or for the Netherlands or Egypt or Florida!

What do we have to do to prevent such disasters from happening? It is plausible that at least we should try to stabilize CO2 concentrations. This, however, will require us to reduce annual CO2-emissions by 60-80 percent, according to the IPCC. Let us optimistically assume that 50 percent will do. But under the present trends, we shall get exactly the opposite. We are heading for a doubling of CO2-emissions:

Fig 16

China, India and other countries are drastically expanding their industrial outputs, their motorized transportation and their energy consuming housing and agriculture. So we shall see China and India to have emissions similar to those of the US:

Fig 17

Fig 18

The world energy pie shows that worldwide we have still an overwhelming dominance of fossil fuels.

Fig 19

In Europe, we have begun systematically to work on the reduction of CO2-emissions. The trading began in December, 2004. Initially, the prices paid per ton of CO2-emissions were at around 8 Euros. Meanwhile, prices have roughly doubled.

Fig 20

One component of our combating greenhouse gas emissions has been the increase of renewable sources of energy. In Germany, we have been quite successful in this:

Fig 21

We were very glad to see a large Chinese delegation at the Renewables 2004 conference in Bonn last year, and many said that China was about to copy the German system and is now planning another such conference this November. However, for all their merits, the renewables will not suffice to solve the problem. The energy pie is simply too large and must be reduced if we want to fight global warming and also avoid a dangerous dependence on nuclear power.

The key to the answer will be a Second Industrial Revolution focussing on the strategic increase of resource productivity. This has been the vision in the book “Factor Four. Doubling Wealth, Halving Resource Use”, which was also translated into Chinese:

Fig 22

It has been known for a long time that lower energy intensity is a sign of modernity:

Fig 23

We therefore see the Factor Four story as a true continuation of technological modernization and progress.

Let me now open a window for you to look into the new universe of eco-efficient technologies. The pictures will mostly compare existing technologies on the left hand side with new technologies on the right hand side that are some four times, or even ten or a hundred times more resource efficient than the old ones.

Fig 24

Let me start with my co-author’s Amory Lovins’ favourite idea, the “hypercar”, which allegedly does 150 miles a gallon, or needs only 1,5 litres per 100 kilometres.

Fig 25

Some remain a bit sceptical about its success but according to Amory, some 2 billion dollars have already been invested in the concept.

Fig 26

The next is Amory Lovins’ institute and home, the Rocky Mountain Institute, high up in the Rocky Mountains, which during much of the year is largely energy-self-sufficient and is easily a factor of ten better regarding energy than typical mountain.

Fig 27

The concept has been transferred ten years ago to ordinary apartment houses in Germany and elsewhere, as “passive houses” making use of solar heat and of heat exchange ventilation.

Fig 28

In my political constituency, Stuttgart, or rather in nearby Fellbach, we have a true zero-external-energy house. It has become a tourist attraction. And part of the excess energy it produces is channelled into a super-efficient car.

You all know the efficient light bulbs that need only a quarter of the electricity used in old incandescent bulbs. China has become the largest manufacturer worldwide of the efficiency bulbs. However, as most of you know, this is not yet the end of the road. Light diodes are coming up that are yet another factor of two or three better than the efficiency bulbs shown on the picture.

Fig 29

This is a small cooling chamber to replace the refrigerator that stands freely in the kitchen. Two weeks ago, I met with a Japanese gentleman who told me that even freely standing refrigerators have now been developed that are seven times more energy efficient that the old ones. The new development was probably triggered by the “Top runner programme” of Japan.

Fig 30

Fig 31

If you replace the old-fashioned filing cabinet technology by CD ROM’s you save more than a factor of ten and you have easier access to your data.

Fig 32

Water scarcity is one of the biggest problems of China. You may therefore be interested in a technology used in Germany that has reduced water consumption twelve fold in paper manufacturing, chiefly by systematically recycling and cleaning waste water.

Fig 33

My friend Professor Ryoichi Yamamoto of Tokyo once sent me the above picture showing a thin rod of steel that has the strength and capacities of otherwise ten times more resource consuming steel.

Fig 34

Video conferences are, of course, something like a factor of one hundred more energy efficient than the otherwise necessary business travel. I admit that video does not easily substitute for a business meeting on the Bahamas.

Fig 35

This is the story of modern, energy intensive agriculture. Winter tomato grown in greenhouses in Holland tend to need a hundred times more energy than they afterwards contain! With intensive cattle farming, the ratio is hardly better. Organic farming, on the other hand, is roughly by a factor of four more energy efficient.

Fig 36

This is the well-known strawberry yoghurt saga established by Stephanie Böge at the Wuppertal Institute. Lorries criss-cross Europe and drive some 8000 kilometres for the manufacturing of strawberry yoghurt. Obviously you could do at least ten times better.

So much perhaps to encourage you to think further about the upcoming technological revolution. Let me close by making a few remarks about methods to arrive there.

China is one of the countries that has established efficiency standards for cars. To meet the 2008 standards, many European and American car manufacturers have still to do considerable homework, while Toyota is well prepared.

Fig 37 [*]

In the business world we seem to see a slight competitive advantage of eco-efficient companies listed in the Dow Jones Sustainability Index over the average listed in the Dow Jones Group Index.

Fig 38

And if you compare different countries using the World Economic Forum’s Competitiveness Index you see a positive correlation with the Sustainable Development Index of countries.

Fig 39

So we seem to be on a good way. However, this is all too slow to reach the necessary factor of four. Let me in closing say a few words about instruments. I am impressed with what I heard in China about the determination with which you are creating incentives for more resource efficient technologies. Moreover, Douglas Ogden this morning mentioned the possibility of tax refunds for companies that achieve ambitious standards, and James Sweeney spoke about appropriate pricing.

Japan has gone a considerable step further with her “top runner programme” that makes the most energy efficient appliance or vehicle the top runner or standard and announces shame on those companies in a few years that still sell outdated, less efficient items. Ultimately they even have to pay a fine.

Germany and other countries have adopted an ecological tax reform to reduce the fiscal load on human labour while making natural resources more expensive.

And at the G 8 Summit that takes place in a few days, we hope countries agree on a geographical extension of climate policy beyond “Kyoto”. We hope that also China, India, Brazil etc will be invited under fair term to join international climate policy.

For this, the North has to understand that the present “grandfathering” approach is unfair to the developing countries and has to be replaced step by step by a system based on per capita allowances, – which would be good for China and India.

Mr. Chairman, ladies and gentlemen, I feel that the race is on worldwide among countries and among companies to take the lead in the Second Industrial Revolution that is driven by the second melody of progress, the melody of a revolutionary increase of resource productivity.

Thank you for your patience and attention!

The subtitle of the report of the World Commission for the Social Dimension of Globalization, which you were involved in, is “Creating opportunities for all”. It also mentions the role of companies and of the UN Global Compact, which Bosch also joined in 2004. What opportunities and initiatives should companies be taking here?

v.W.: Companies should recognize and apply the ILO’s core labour standards also within the supply chain. Companies may wish to establish assessments of climate or environmental impacts and draw their customers’ attention to them. Global Compact companies may also get involved in efforts to achieve an international i.e. competition-neutral) control of CO2 emissions and of the resource consumption. Global Compact companies could instruct their own pension funds to focus on ethical or ecological investments.

When the Kyoto protocol comes into force in February, this will mean greater climate protection. Your view is that the country that manages to disengage its economic development most efficiently from its CO2 emissions will have significant competitive advantages. How can this advantage be achieved, and with what innovations?

Japan has developed a “top runner” programme that defines an efficiency standard for energy consuming vehicles and appliances. Products failing to meet that standard will be phased out in the long run. The EU should consider joining this programme. Climate targets should be developed and agreed for the period after 2012. They should help stabilizing temperatures at a level not exceeding two degrees Celsius above pre-industrial levels. For this, CO2 concentrations should rather not exceed 500 ppm.

In renewable energies, the German export industry is one of the world market leaders. China has announced that it will be generating 12 percent of its electricity supply from renewable energies by 2020. This ambition is underlined by its organization of a global conference on renewable energy in 2005, as a follow up to the “renewables 2004” conference in Bonn. Does that mean that German companies, with their know-how, can look forward to a good future in China as far as renewable energy is concerned?

Germany seems to have established itself as China’s preferred partner for renewable energies. This could mean major market opportunities for German companies.

At the beginning of this year you are publishing a new report to the Club of Rome. In the report, you deal with the “limits to privatization,” and conclude that the balance between public and private sector that more or less existed up to 1990 has been lost, and that the economy is now leaning more toward the private sector. What do you feel are the consequences of this, and where do you see the limits to privatization?

I co-edited the book “Limits to Privatization – How to Avoid Too Much of a Good Thing” with professors Oran Young (Univ. of California) and Matthias Finger (Lausanne, Switzerland). It features some 50 examples of privatization, both successes and failures, in every relevant sector. The book observes an increasing imbalance between the public and private sectors, – to the detriment of the public sector. The private sector must be aware that there are many “public goods” that markets will never produce or maintain. Among them are primary education, the legal system, certain infrastructures, long term environmental protection, and a minimum of social justice.

Governance and Corporate Social Responsibility stand for two approaches that are intended to contribute to a new balance between government, business, and civil society. What hopes do you personally place in the voluntary assumption of responsibility by companies, and where do you feel is the most urgent need for change in management structures?

There is a need for globally valid rules for business. There should be no incentive for companies to disregard minimum standards of human or ecological decency.Voluntary rules of Corporate Social Responsibility (CSR) are helpful but not sufficient. Governance and CSR are mutually complementary. CSR pioneers may enjoy first mover advantages as ambitious international rules are gradually emerging and are gaining broader recognition.

Why Sustainable Development?

We live in a finite world. Ultimately, there is no way around production and consumption patterns that are sustainable. Ultimately, customers, engineers, managers and politicians will show a strict priority for the respect of nature and the environment.

To be sure, global competition for highest cost-benefit ratios leaves little breathing space for such long-term considerations. But at any moment in time it is legitimate to ask oneself if the time has come to now make sustainable production methods and ecologically benign products the priority for the company.

Many people in the business community believe that most of the environmental homework has been done leaving not much to do. This optimistic conviction is based on the inverted U-curve”. Countries typically start poor and clean. Then they industrialise and become rich and dirty. Once they are rich enough to afford costly pollution control, they finally become rich and clean.

Fig. 1: Countries historically started poor and clean, then got industrialised and dirty and ended up rich and clean.

The trouble is that ”rich and clean” involves per capita consumption levels of depletable resources easily twenty times the rate of the ”poor and clean” stage. In the language of William Rees and Matthis Wackernagel (1992), lifestyles in the rich and clean countries involve ”ecological footprints” of some four hectares per person. Similarly, Friedrich Schmidt-Bleek has developed the concept of ”ecological rucksacks”. Every average Japanese causes an ecological rucksack every year of some 45 tons. Germans cause even heavier rucksacks weighing some 60 tons. Heaviest, of course, are the US American rucksacks of some 80 tons annually.

All in all, we are far from a harmonious situation. In fact the daily toll of environmental damages can be seen as absolutely alarming, as Fig. 2 is summarising.

Fig. 2: The alarming daily toll of environmental destruction.

Among the most alarming effects of our footprints and of the rucksacks is the rapid loss of biodiversity. At present, we are losing some twenty, perhaps up to one hundred plant and animal species every day. This is mostly due to the destruction of natural habitats that have been the home to hundreds of thousands of biological species, some of them rather inconspicuous but nevertheless important in the interlocking webs of ecosystems. Habitat destruction mostly results from land conversion for mining, agricultural use, forest monoculture, or settlements. Even if much of the land degradation is taking place in the developing countries, it is often exports of timber, ores, fodder and fruits to the North that cause the degradation. In other words, we in the rich countries tend to export our ecological footprints to the South

One of the most disquieting aspects of environmental change is the greenhouse effect. The Intergovernmental Panel on Climate Change (IPCC) has published fears of global warming by up to 5 degrees during this century. (Fig. 3).

Fig 3: Projections of global warming until 2100 (Source: IPCC, 2001).

Global warming can be accompanied by a further rise of the sea levels. Fig. 4 shows how the coast lines of Italy reacted to different levels of the sea water table.

Fig. 4: Italy during the last Ice Age and during the Pliocene.

There is still a lot of ice on the Antarctic and on Greenland, enough to flood Holland, Bangladesh, Egypt, Florida and much of Germany.

We should by all means avoid such disasters. The IPCC has suggested that in order to stabilise carbon dioxide concentrations we should reduce carbon dioxide emissions by some 60 to 80 percent, say by 2050. On the other hand, we learn from the World Energy Council, that the demand for energy, and with it the emissions of carbon dioxide, are likely to rise steeply and are most likely to at least double within that period. So there is a gap as large as a factor of four which will have to be closed.

Nuclear energy can’t close the gap. Today, nuclear energy is a mere six percent of the world energy pie, and in most countries, even the most ardent defenders of nuclear energy have stopped ordering any new reactors. Even a neck-breaking rush towards tripling nuclear energy supplies in the world would not buy more than is an increase from six to eighteen percent of the energy pie. And if that pie is doubling, we are falling back to a mere nine percent.

The substitution of fossil fuels by renewables is a lot nicer to the environment. But then wind and solar make up only 0.5% of the present pie. Let us assume a heroic strategy of increasing it twenty fold. Then we have reached ten percent of the present pie, but a mere five percent of the double sized pie.

Let me conclude this introductory section by stating plainly that energy policies too are in a massive dilemma.

After the Industrial Revolution the Eco-Efficiency Revolution

The challenges of sustainability, of biodiversity protection and of climatic change look breathtaking. Fortunately, there is hope. Much of this hope is rooted in technological progress. But the task will be no smaller than the adventure of the Industrial Revolution. Having listened to some of the participants of this conference in advance, I am confident that the radiation curing industry can play a significant part in our new adventure of technological progress. However, I don’t claim the competence for giving you any special technological advice. Let me instead try and characterise the broader features of that new technological revolution.

In the early days of the Industrial Revolution, technology was mostly driven by the desire of economic expansion. The main emphasis was laid on the increase of labour productivity, which may have risen twenty fold during the last 150 years. This progress becomes visible in the speed of our vehicles, in the power of our machines, in the organisational miracles of industrial production lines and in the unprecedented skills of modern information technologies.

The emphasis on labour productivity was very reasonable until quite recently when human labour was indeed very inefficient and very hard too. The resources of nature seemed to be nearly unlimited. So the exploitation of nature seemed like a legitimate and natural part of the game for much of technological history.

Today we are living in a completely different world from the early 19th century. Labour today is abundant, labour productivity is very high, and the real scarce resource is nature. This means it is high time now to concentrate our efforts on the increase of resource productivity. Even purely economic — and social — reasons speak for it. Slowing down the increase of labour productivity while speeding up resource productivity should make countries richer, not poorer.

Shifting emphasis to resource productivity should be the best answer also to the challenge of sustainable development. The World Business Council for Sustainable Development now speaks of Eco-Efficiency as a new guiding term. And the Wuppertal Institute of which I have been the founding president, gives ambitious goals for the increase of resource productivity. For the use of materials, my friend Friedrich Schmidt-Bleek calls for a decupling of resource productivity. But for energy, I suggest a more modest figure of a factor of four. At any rate, we are speaking of productivity jumps equally impressive as those characteristic of the Industrial Revolution. Let us therefore speak of the Eco-Efficiency Revolution, which we shall be forced to launch very soon.

The Eco-Efficiency Revolution is perhaps the only strategy allowing a reduction in size of the ecological footprints without jeopardising employment and competitiveness.

Factor Four

The good news is that quadrupling resource productivity is technologically feasible. A 1995 Report to the Club of Rome (in English: Weizsäcker, Lovins and Lovins, 1997) features fifty examples for the potential of increasing resource productivity by a factor of four at least. Twenty examples were selected in the field of energy, twenty in material resource productivity, and ten in transportation.

Fig. 5: Factor Four was translated into twelve languages including Chinese and Japanese.

My co-author Amory Lovins lives in and works at the “Rocky Mountain Institute”, some 2000 metres above sea level in a truly cold climate. And yet his home needs almost no external energy. It is easily a factor of four more energy efficient than ordinary alpine buildings. The next picture compares the two in terms of energy productivity.

Fig. 6: The Rocky Mountain Institute is perhaps ten times more energy efficient than an ordinary alpine house.

Another very attractive Factor Four example is what my co-author Amory Lovins has dubbed the hypercar {Fig 7}. By almost entirely redesigning cars, making them light-weight and still crash-resistant, and by using modern hybrid engines, the average fuel efficiency can be pushed up to 150 miles per gallon, which is more than four times better than today’s fleets.

Fig. 7: Amory Lovins’ “Hypercar” (right) is five times as fuel efficient as ordinary cars (left).

Other examples include light bulbs, refrigerators, air conditioners, TV sets, mechanical fans, pumps and motors, computers and other office equipment.

Also renewable sources of energy will play an important role in the efficiency revolution. They may not by themselves save energy but they are at least ”carbon-efficient” and lend themselves to being combined with efficiency technologies, e.g. the use of passive solar energy in buildings can be optimised by the so-called translucent insulation technique.

A different and very important sector of energy use is nutrition. By reducing the excessive use of fertilisers and the transportation of fodder, and by slightly cutting meat consumption, energy requirements for a healthy diet can be cut by a factor of four.

The twenty examples of revolutionising material productivity range from construction and durable office furniture, to water in homes, in paper manufacturing and to high tech recyclable plastics for wrapping and catering. One fine example is the replacement of a clumsy paper-based filing cabinet by a modern CD ROM system. There you save more than a factor of ten even if you generously include the ”ecological rucksacks” of the metal contained in the disks. One example is modern steel, which can be easily four times as resource efficient per unit of results obtained (Fig. 8)

Fig. 8: Modern steel can be fabulously strong and can help saving 75% materials.

Let me present one last example from our book, the logistics of the production of strawberry yoghurt. Stefanie Böge has found out that for manufacturing a cup of strawberry yoghurt in Germany you would typically let lorries criss-cross central Europe and make 8000 kilometres, if suppliers and the suppliers of the suppliers are counted. It can easily be proven that you can do an equivalent job with only a thousand kilometres, which again is more than a factor of four. (Fig. 9)

Fig. 9: The distance of total lorry traffic for the manufacture of strawberry yoghurt today (left) and in an energy efficient future (right).

I may have opened a window for you into a distant future of technologies and everyday habits of people, There will be millions of small transformations, some of them quite inconspicuous, that make up the factor four revolution. I am perfectly confident that the revolution will be as benign as the industrial revolution, although surely there will be losers, chiefly among those who do not want or cannot keep pace. That, however, is not exactly new in the history of industry.

Profitability, long term and short term

Needless to say much of the efficiency revolution is not going to happen unless the framework for doing business is changed. Efficiency must be made profitable. Fortunately, some eco-efficiency is profitable now. (Fig. 10).

Fig. 10: A portfolio of stocks of ecological “best in class” companies had a better performance than the DJGI

A portfolio of stocks of ecological “best in class” companies had a better performance than the Dow Jones Group Index. Companies paying attention to the resource and energy flows going through the firm, tend to gain internal transparency and to enjoy better staff motivation and better customer relations. This is perhaps the most convincing explanation for their encouraging stock exchange performance.

It is to be feared, however, that the potential for making profits by eco-efficiency measures will be very limited if the present world market conditions prevail. Energy and natural resources are still too cheap because markets are rather blind with regard to long term scarcities and to such developments as the greenhouse effect.

Moreover, conventional policies in most countries have even subsidised the use of natural resources. André de Moor (de Moor and Calamai, 1997) has estimated that some 700 billion dollars are spent annually in subventions given to the four fields of energy consumption, water, agriculture and motor transport. This does not even account for all the tax advantages, free infrastructure and land given to investors. De-subsidising resource use will be an important part of ecological policy worldwide.

Another and related policy tool is ecological tax reform. In a world of growing unemployment and of scarce natural resources it just doesn’t make sense to draw the biggest part of fiscal revenues from human labour while resource use is essentially free of charges. The German government has made some first steps in that direction, as have many other European countries. Perhaps certain details were not well designed so that the programme is not exactly popular.

The EU is now introducing an international trade regime for permits of carbon dioxide emissions. Economists believe that this instrument can be more cost-effective than ecological tax reform.

This is just the beginning. I remain confident that future generations will find it easy to accept market interventions making scare resources dearer and abundant resources cheaper. That is pure economic rationality and should make countries richer, not poorer.

I hope that your innovative branch of industry with it’s fascinating advances in UV/EB and radiation curing will be part of the driving force for a more prosperous and more sustainable society world-wide!

The answer to this question should be yes and no.

Yes, we are closer than ten years ago. During all of he 1990s, an irritatingly optimistic mindset was dominating the world. The very expression of ‘saving the planet’ would not have been politically correct in these days, because it sounds ‘pessimistic’.

What caused the air of optimism of the 1990s? The Cold War was over, alright, that was a great relief because it was also the end of the fear of a Third World War. Capitalism was celebrated as the only remaining ideology, constituting the ‘end of history’, as Francis Fukuyama put it. In its radical, Anglo-Saxon version it was politically hailed as the engine of growth and thereby as a cure-all, with slogans like “rising tide lift all boats”. ‘Creative destruction’ was seen as legitimate whenever what was to be destroyed had a smell of communism. Well, markets are a growth engine and a healthy cleansing mechanism, but at least two billion people felt outright cheated and exploited. They saw their ‘boats’ sinking, not rising at all.

Stock exchange quotations were another cause of optimism, as they seemed to rise without limits. That was a deception, too, as the collapse of the ‘dot com’ bubble showed in 2000. Concerning the environment, the prevailing paradigm was the optimistic Kuznets curve of pollution, meaning that once countries turn rich they will spend enough money on pollution control, and countries end up rich and clean. In terms of local pollution, the Kuznets curve was a reality, but for global warming and biodiversity losses the paradigm was dead wrong.

I must say, I was in a state of alarm during the late 1990s about the careless optimism and the uncompromising arrogance behind it. I felt rather helpless raising my voice against it.

So I see with a degree of relief that the days of the blatant type of arrogance are over and that it has become almost mainstream once again to address the real problems. What made this sea change happen? There were many different factors. The billions of people in their ‘sinking boats’ are no longer silent. The world community has addressed their situation in the Millennium Development Goals (MDG), acknowledging that markets will not do the trick. The end of the dot com bubble was a wake up call to some but the broader public did not hear the signals until the sub-prime mortgage crisis of 2007, originating in America but spreading worldwide. Some of the once celebrated investment gurus and their institutions got unmasked as irresponsible speculators using the money of credulous clients.

In the political arena, the military and ideological answer to the insidious attacks on the World Trade Center and other targets (‘9/11’), the “War on Terror”, more and more became a nightmare for all parties involved. The arrogant US unilateralism once impersonated by the Rumsfeld-Wolfowitz Pentagon lost its support even in the White House, let alone the US Congress after its mid term elections.

The environment is back on stage, after a quarter century of denial among the leading classes in the USA, and under the weight of evidence from the Intergovernmental Panel on Climate Change and the devastating pollution in the industrial centres of the high growth countries, notably China. The EU has taken the lead in politically addressing global warming, setting up the ETS, the European Trading System for carbon dioxide emissions. The two remaining candidates for the US presidency have expressed a clear commitment on mitigating global warming. China has become very serious about addressing pollution, climate, and energy efficiency. Renewable sources of energy constitute a dynamic growth sector. The Convention on Biological Diversity (CBD) is enjoying increasing visibility in the signatory states, i.e. nearly all states except the USA.

It is fair to summarise, then, that the last ten years have seen a tidal change in appreciation of the real problems the world community. Overcoming the arrogant optimism of the 1990 has been a huge and necessary progress.

It was necessary, but is surely not sufficient for an agenda of saving the planet. This is the core of the No answer.

Global warming got worse throughout the past ten years. New figures and extrapolations, e.g. from NASA’s James Hanson seem to show that stabilising atmospheric carbon dioxide at 450 ppm is far from sufficient and that we should rather aim at 350 ppm, which is still well above the pre-industrial levels of 280 ppm.

Biodiversity losses have accelerated, notably in the tropical countries. Fish stock depletion went on and partly accelerated. China aggressively began to access mineral and energy resources in Africa and elsewhere so as to continue its steep increase of resource consumption. India, Brazil, South Africa, Angola and a few other countries enjoy tremendous growth rates, all based on accelerated resource extraction, at a comfortably high price level. No end of the trend is in sight, not even a flattening of the curves. All countries of the world seem to work under the assumption that they have a right to the same kind of prosperity as the USA. And after many years of brainwashing that the American way of life was the best one could aim at, this assumption is hard to deny. But six or eventually ten billion people living by US American life styles is just not possible. We would need four or five planets Earth to accommodate their ecological footprints, according to the Global Footprints Network.

Thus in terms of climate and the ecological situation, the picture has become quite a bit grimmer, not better.

How can we now deal with this odd combination of the Yes and No answers? I submit that we can break out of the vicious circle of seeking wealth in material growth alone. I suppose we can decouple wealth creation from energy and material consumption very much like we decoupled wealth creation from the number of hours of human labour. The latter was the achievement of the Industrial Revolution. Labour productivity rose easily twenty fold in the course of 150 years of industrialisation. In other words, from one hour of human labour we learned to extract twenty times more wealth. Now is the time to do the same for energy and materials. We can learn and must learn to extract four times, ten times, and eventually twenty times as much wealth from one barrel of oil or from one ton of bauxite as we do today. Technologically speaking, this should not be more difficult than the rise of labour productivity. Resource productivity should become the core melody of the next industrial revolution.

Labour productivity rose in parallel with wages. Rising wages were justified by rising labour productivity, and rising labour cost stimulated ever further increases of labour productivity. Energy prices, on the other hand saw a secular decline (in constant dollars) over 200 years. The latest price hikes have not even brought us back to the price levels of some thirty years ago. Tragically, the political zeal has always been to keep energy prices as low as possible, thereby frustrating most attempts at increasing energy productivity. Energy price elasticity is very much a long term, not a short term affair. Infrastructure investments, which are crucial for an energy efficient society, take a lot of time.

What our societies ought to learn now is creating a long term trajectory of energy prices slowly but steadily and predictably rising in parallel with energy productivity. By definition, this would not cause any hardship, on average. But it would set a clear signal to investors and infrastructure planners that energy efficiency and productivity will become ever more profitable and necessary. It is bound to become more profitable and sexier even than the renewable energies.

If our societies, starting perhaps with the EU, embrace this new agenda of technological progress, and if later historians see the period between 1998 and 2008 the kick-off period for this new technological revolution, I suppose that those historians will agree that this time span has brought us closer to saving the planet.

Introduction

I feel greatly honoured being invited as your tenth speaker in the Business Leaders Conference on Environment and Development. Nihon Keizai Shimbun started the series in the year of the Earth Summit of Rio de Janeiro, the UN Conference on Environment and Development. 1992 was the year of culmination for the topics of environment and development. Since that year, public attention worldwide has to an alarming extent deserted both topics.

I shall briefly offer some unconventional views on Japan and then move on to discuss the megatrend of globalisation which I see as the main reason for the massive neglect of the environment. I shall conclude with an attempt at establishing a new sense of direction for technology, civilisation and investments.

Is Japan ill? I rather think the opposite

So let me begin with my personal views on your country. Foreign commentators tend to depict Japan as stagnating and ill. Increasingly, even the Japanese seem to believe in this negative assessment.

Of course, in a world in which growth is the yardstick of success, you cannot be too happy. Of course, one feels worried by non-performing loans worth 40 trillian Yen and by a national debt of 400 million Yen.

And, of course, everybody right in his mind has to support your Prime Minister Jun-ichiro Koizumi’s bold reform policies including the privatization of some of the tokushu-hou-jin (Special Public Corporation). He also addresses new competitive frontiers which are to be explored chiefly by the private sector.

However, let me as a guest and an outsider say a few words of reassurance to you. I have the privilege of visiting Japan rather regularly. What I see is a strong and prospering country proud of its history, full of high technology industry, pioneering in exquisite services. I visit top class universities, see happy school children in pretty school uniforms and enjoy clean and well-functioning public transport. I feel safe in the absence of crime and violence. Best of all, the people you meet on the streets look happy and respond with exquisite politeness to any question of a foreigner. Compare Japan to the violence situation in US American cities, in Colombia or in South Africa! Compare Japan with the poverty situation in most developing countries. Compare Japanese tolerance with the religious or political intolerance and fighting in half of the countries of the world! No, I find it squarely scandalous of journalists and economic analysts to call Japan a sick country.

One of your and of PM Koizumi’s worries is the lack of economic growth. But then let us reflect for a moment. What is the meaning of zero growth in a situation of a stable population and of high prosperity? It still means a huge turn-over; it can mean an increasing stock of wealth. It only means that the flow, covering both increase and maintenance of wealth is not bigger than it was in the preceding year. As a matter of fact, private financial assets are nearly four times as high as your state deficit meaning that your country as a whole is not indebted.

There are only two worrying facts associated with zero growth. One is that some competitors may eventually outgrow you. And the other is that technological advances produce higher labour productivity, which means an increase of unemployment, a phenomenon unknown to Japan for many happy decades.

I shall address both troublesome facts later. As I said before, I am not suggesting that Japan cannot be improved. I share the view in particular that Japanese consumers would do a good thing returning to an optimistic habit of spending. But I am suggesting that all measures of improvement including the Koizumi reforms would greatly benefit if the country would enjoy a new and clear sense of direction.

A clear sense of direction means that investors know where to invest. Banks trust that the investments make sense. And consumers want to be “with it” and re-discover the joys of owning the right things.

Blind markets

Markets in our days hardly create a new sense of direction. They did so in the past when essentially all goods and services were in short supply. Industry was only too happy to produce all that was needed. During this happy period the increase of labour productivity was only too welcome. It meant that ever more could be produced and that wages could steadily rise. Japan surely had a strong state dominating the economy. But the business community didn’t mind. “Japan Incorporated” benefited all during that period.

Let me repeat and highlight one aspect of this period. It is the dominance of the state over the private sector. Fig. 1 symbolises this situation, — in a caricature fashion.

Fig. 1: The state dominates but business is happy.

What was true for Japan, could similarly be found in West Germany, in Canada and essentially in all OECD countries. In the USA, in particular, the strong leadership of the state, the serious quest for social justice and the relatively humble role of the private sector, could be observed since the days of John F. Kennedy — not to mention Franklin D. Roosevelt a generation earlier.

But then, after the turbulences of the oil crisis and in its wake the novel arrogance of Islamic fundamentalism, first culminating in the Iran hostage crisis, the USA underwent profound changes. Ronald Reagan enjoying a landslide victory in 1980 pulled out of the welfare state and in foreign policy steered the country into harsh confrontation against what he called the “evil empire”. He promised to reduce taxes for the achievers and invited private business to take its profits home. In effect you could see the state on retreat.

Fig. 2: The 1980s: The state on retreat.

Similar developments could be observed in Britain, Germany and several other countries. At the time, I believe, it was good for these countries that the private sector assumed additional responsibilities and introduced efficiencies unknown to some state owned agencies. But in some cases such as the privatization of the British rail it went all wrong. Anyway what I am suggesting is for each country to maintain a healthy balance between public and private.

Globalisation

In many parts of the world we seem to have lost that balance. When the Soviet bloc collapsed, many nation states in the West and in the developing world all of a sudden lost much of their bargaining position towards the international capital markets. This bargaining position had been rooted to a large extent in the very existence of the communist threat. It forced capital owners to accept progressive income taxes, social security and environmental regulation. This was simply because the socially inclusive market economy was still better for capital owners than any kind inclination of a country to go communist.

Now, after 1990, that comfortable bargaining position of the nation state was gone. What now happened, was called globalisation and was characterised by the dominance over the smaller nation states of international capital markets.

Fig. 3: Globalisation means the dominance of the private sector.

This is our situation today. First, the world (and not only business) was celebrating it. The spectre of a third world war had disappeared. . Hundreds of million of people were liberated from dull, authoritarian and inefficient regimes. Huge peace dividends were expected to arrive. The stock markets soared. Francis Fukuyama in America called it the end of history, i.e. the end of ideological quarrels. Markets were believed to give guidance towards ever increasing prosperity. Nobody dared to question whether we had a reliable sense of direction.

Nobody dared to raise doubts about the legitimacy of the dominance of the private sector because the dominance of the state had conspicuously lost its legitimacy.

However, the euphoria didn’t last very long. Soon people began to realise that the gap between the rich and the poor was steadily widening. The income gap between the richest and the poorest twenty percent of the world population rose to a shocking factor of 75 during the 1990’s.

Fig. 4: The widening gap of income world wide.

Environmental policy became a nightmarish task because everybody’s immediate concern was now to survive in the unforgiving struggles of globalisation.

Even in their home turf, financial markets performed a lot poorer than expected In rapid succession, currencies from Eastern Europe, Western Europe, Mexico, the Asian emerging markets, Turkey and Argentina were subject to extremely damaging turbulences. Worst of all, the “new economy bubble” imploded and with it the entire euphoria of the global stock market.

The states, guardians of the public goods, suffered from stagnating revenues, in part self-inflicted through a rat-race for ever decreasing corporate taxation.

Fig. 5: Diminishing corporate tax rates in OECD and EU member states.

Ordinary people got increasingly worried and angry about the arrogance of the dominant market ideology. In Seattle, Gothenburg, Genoa you could see them marching and protesting. Protesters mostly represented the losers of globalisation. They also represented in a great variety of ways public goods such as the environment, human rights, social equity, farmers rights, cultural diversity, or the rights of indigenous people. You can ask any of these people if they see a purely monetarised globalisation as damaging to the public goods they defend. And their answer will clearly be “YES”.

Fig. 6: ¥€$.

Let us take stock for a moment. The victory of what we all considered the superior systems namely the democracy-based market economy, appears to be in the doldrums. People worldwide seek for a sense of direction, but in vain. Except, perhaps in China and America. In China they still enjoy the clear sense of direction of just increasing economic output. And in the US they don’t allow any critical questions about what their great country has been fighting for ages. They prefer to put the blame on the outside world, that is Islamic fundamentalism, coward Europeans, or a stagnating Japanese economy.

The unsustainable American way of life

I fear that we won’t arrive at a new and reliable sense of direction unless we dare to question – against all political correctness – the viability of the US model of economic growth or, what is usually called the American way of life.

In doing so, we have to focus our attention on the topic of our conference, environment and development. Let me submit that the American way of life is squarely unsustainable.

Of course, our friends from America don’t see it that way. To them, the USA represent the far end of what is often called the environmental Kusnets curve.

Fig. 7: The inverted U-curve of pollution.

The curve shows the history of the Industrial Revolution. Countries typically start off poor and clean. In the course of industrialisation they become rich and dirty. And finally they become so rich that they can afford expensive pollution control making them rich and clean. Japan, like the USA or Germany, is perfect example of this development. The curve justified in a sense what Indira Gandhi said 30 years ago, namely that “poverty is the biggest polluter”.

The trouble is that the situation of “rich and clean” is not automatically “sustainable”. Facing today’s major environmental problems, we should even call economic wealth the biggest polluter, although this time pollution is not perhaps the right term for the environmental damages. Fig 8 sums it up:

Fig. 8: The daily toll of environmental destruction.

Here we see the daily toll of global environmental destruction. We seem to be losing up to 100 animal or plant species every day. We blow 60 million tons of carbon dioxide into the air, thus changing the atmosphere. Over-fishing and deforestation go on almost unmitigated. Much of the damages stem from excessive land-use, material turnovers and energy consumption in the rich and clean countries. The USA is clearly leading this unsustainable direction of development.

Greenhouse effect and other ecological troubles

In assessing the problems and opportunities let me concentrate on the greenhouse effect, but I assure you that the assessment of land use and of material turnovers would lead to very similar considerations.

Carbon dioxide concentrations are on the rise since the early days of industrialisation. The next picture shows the trend for the last couple of decades:

Fig. 9: The steady increase of CO2 concentrations.

The trouble comes when you look at the correlation between CO2 concentrations and global temperatures.

Fig. 10: The “Vostok” expedition found a close correlation between CO2-concentrations and atmospheric temperatures during the last 160.000 years.

We can also see that in the industrial age the blue curve of CO2 is mounting steeply upward. Climatologists expect temperatures to rise correspondingly, and we are already seeing it happen. Nearly each year during the last 15 years has been the hottest year since scientific weather recordings started. During the last 4 years alone we have had twelve or more gigantic natural disasters due to weather in various places on earth including Asia and Europe.

In 2001, the Intergovernmental Panel on Climate Change projected a dramatic increase of global temperatures to occur until the end of this century.

Fig. 11: IPCC’s projection of temperatures until 2100.

Massive changes in the face of the planet could result. Temperatures alone and a few local disasters might not by themselves be the core of the drama. A hotter candidate for the core of the problem is the sea water table (Fig. 12).

Fig. 12: The sea water table goes with atmospheric temperatures.

In this picture I have added as a green line the sea water table during the last 160.000 years. I invite you to have a look at the difference between a high and low sea-levels. It is more than 100 metres! This formidable variance has a major impact on the coast lines, as can be seen on the next slide:

Fig. 13: Italian coast lines during the last Ice Age and during the Pliocene.

This is Italy some 20.000 years ago, during the last Ice Age. But now look at the coast line some 2 million years ago, during a truly hot age. Imagine, ladies and gentlemen, what this picture would mean for the Tokyo and Kansai areas or for Bangladesh, the Netherlands or for Egypt. What may cause more anxiety still is the potential dynamics of change.

Fig. 14: The collapse, 7700 years ago, of the ice shield covering Labrador and the Hudson Bay.

Studying the British coast line and flood marks left at the rocks rising from the sea, Professor Michael Tooley found that about 7,700 years ago global sea-levels must have risen by 7-8 metres within a few decades or even within a few weeks. His explanation is that the ice shield then covering Labrador and the Hudson Bay were breaking off into the sea within a short period of time. I assume that this was the historical backdrop for the Atlantis and the Biblical Deluge sagas.

If we now go on heating up the atmosphere, major parts of the Antarctic or of Greenland can break off at some unpredictable moment during the next 200 years.

If we want to avoid such disasters, we would be well advised at least to stabilise CO2-concentrations. In order to achieve that, we would have to reduce annual emissions by 60%-80%, according to the Intergovernmental Panel on Climate Change. Let us say – optimistically – that we need only a 50% reduction. This is as far higher ambition than laid down in the Kyoto Protocol. However, halving CO2-emissions may be extremely difficult to achieve because energy experts tell us that we shall rather incur a doubling of CO2 concentrations within a few decades.

Fig. 15: CO2-emissions should be halved to achieve stabilisation of CO2-concentrations, but energy demand is more than doubling.

The reason is that developing countries so far have much lower CO2-emissions per capita than the rich countries. China, Brazil and Ethiopia have every reason now to do exactly what we have demonstrated to them as the core of our industrial success story, namely high energy consumption accompanied by high CO2 emissions.

Factor Four

A gap is opening before us which is at least as large as a factor of four.

Some people both in Japan and Germany believe that the gap can be closed using nuclear power. Without going into any detail of this controversial issue let me only say that after 11th September 2001, safety assessments of nuclear installations have to be re-written from the scratch — with an essentially uncertain outcome. Nikkei President Tsuruta was kind enough to ask me how Germany was handling its decision of phasing out nuclear power while still subscribing to the Kyoto Protocol. One part of the answer is renewable sources of energy. However, we have to admit that there are also limits lying in their costs and in their modest energy densities.

The best solution, I suggest, is a strategy of systematically increasing energy productivity. The textbook for this has the title “Factor Four: Doubling Wealth, Halving Resource Use” which I co-authored with my American friend Amory Lovins and his wife Hunter Lovins.

Fig. 16: Factor Four: translated into many languages.

The book heralds a new industrial revolution. It thereby also conveys a new sense of direction for technological progress. It may encourage investors to go for new investments and for new technologies.

Quadrupling resource productivity, eventually even increasing it by a factor of ten, as my friend Friedrich Schmidt-Bleek is suggesting, is a gigantic challenge requiring the commitment of the brightest engineers and the boldest business people. It is my sincere hope that both Japan and Germany will play major roles in bringing that new technological revolution about.

Let me make the analogy to the industrial revolution more explicit. During the first fifty or seventy years of the industrial revolution, the world has seen a fourfold increase of labour productivity. Later, labour productivity increases even accelerated, owing to better technological communication and ever increasing costs of human labour.

Today, albeit expensive, labour is no longer a scarce factor. According to statistics of the International Labour Organisation (ILO), over 800 million people are unemployed or have only access to marginal work. In this day and age, it somehow doesn’t make much sense for the world economy to go on and maximise robotics and other labour saving technologies while neglecting productivity of the really scarce factor of our days, natural resources.

The mentioned book, Factor Four, which also was translated into Japanese, features 50 examples showing the potential of improving resource productivity at least by a factor of four. Twenty examples relate to energy productivity, twenty to solid material productivity, and ten to the transport sector.

Let me briefly introduce you to the new universe of factor four technologies. For this I shall show you some pictures beginning with Amory Lovins’ present favourite example, “Hypercar”:

Fig. 17: Hypercar is four times more fuel efficient than normal automobiles.

Hypercar, seen on the right hand side, is designed to use only one-and-a-half litres per hundred kilometres. I won’t go into technical details of this ultra-light vehicle.

The second example is what we refer to as the “passive house” which in Germany’s cold climate needs hardly any external heating except for some passive solar energy.

Fig. 18: Passive house, a concept to save 90% of the typical heating costs.

It is very well insulated. It needs no radiators and thus saves space and money making it commercially competitive with ordinary constructions. It is not only insulation and energy management that counts. Nearly equally important is the materials of construction. Wood is among the best, of course, in particular if we consider the carbon balance.

Fig. 19: Wooden construction saves energy and CO2.

Very familiar to you all are light bulbs and their modern efficiency substitutes.

Fig. 20: Fluorescent light bulbs are four times more efficient than incandescent bulbs.

A more recent development is light diodes which are still a factor of two better than fluorescent lamps.

Lets us now turn to household appliances. When you replace your free-standing refrigerator with a cold-storage room built into the north wall of the house, you can also save approximately a factor of four both in terms of energy and materials.

Fig. 21: FRIA, the non-mobile refrigerator.

In tropical countries, but also during the summer in Japan, the biggest energy eater in office and apartment buildings is air-conditioning. In Singapore, we found an engineer, Mr Lee Eng Lock, who builds air-conditioning systems that need some 70% less power than conventional ones. Imagine the savings for office towers and tourist hotels all around the hot belt of this planet.

When you replace an old filing cabinet with a CD-ROM system, you have a Factor 10 or more in material and resource productivity and you have much swifter access to your data.

Water is now one of the scarcest resources in the world. Several examples in our book deal with factor four water efficiency in agriculture, industry and households.

One important industry for water consumption is textiles. We found a small German manufacturer, Hess Natur, advertising clothes that overall need roughly one quarter of the natural resources including fresh water needed in ordinary products.

Fig. 22: Textiles with a cradle-to-grave resource use four times lower than average.

Another strategy of saving materials and energy is improving mechanical properties of such simple materials as steel. I recently learned about exciting advances in the Japanese steel industry.

Fig. 23: Innovative steel from Japan.

Instead of being a clumsy and heavy material, this extraordinary steel rod is incredibly light and elegant and yet extremely robust.

Let me finally turn to food. When you eat tomatoes from the Netherlands during the winter season, it could be that around 100 Kcal have been invested so that you can afterwards eat a Kcal tomato. In the case of European intensive husbandry beef each Kcal of beef requires some 20 Kcal of extended energy inputs. Ocean fishing, I am sorry to say, isn’t much better. With a diet, which is a little more seasonal, containing somewhat less meat and fish and stemming from organic farming or aquaculture you can easily save a Factor 4 in energy consumption, as the next picture indicates:

Fig. 24: Food can “eat” a lot of energy — but need not.

Stefanie Böge of the Wuppertal Institute has looked into the transport intensity involved in the production of strawberry yoghurt in Germany.

Fig. 25: 8.000 kilometres for strawberry yoghurt? It is too much!

She found that lorries are criss-crossing Europe at a total of around 8,000 km for the production of a cup of strawberry yoghurt. Clearly, this is not necessary.

Not only yoghurt journeys can be rationalised. Many business trips can be saved using videoconferences. And letters and manuscripts don’t always need airmail from Japan to Europe. Much can be sent by e-mail, saving a factor of 100 or 1000 in resource use. I am fully aware that substituting electronic dispatch for air transport in the case of tourism and Business Leaders Conferences is not quite so simple. Besides, people like to visit Tokyo for sight-seeing. However, in each case it is worth reflecting if a trip is really necessary.

In many cases the magical factor of four is not attained in one go. German chemical industry for instance managed to increase its overall energy productivity by a factor of four during a period of thirty years. Hundreds if not thousands of little inventions and process improvements were instrumental in bringing this success story about. You may not get much acclaim for this complex and incremental factor four story. But the effect is all the same.

Making it profitable

After having sketched out the shape of the new universe of factor four technologies I should like to turn to some economic and political questions. What can we do to make this technology shift profitable? Fortunately a reasonably large part of the eco-efficiency measures are already profitable. This is particularly true in developing countries. At my last journey to China, I read a brochure from a German consultancy working on strategies to reduce CO2 in China. And this is what they found:

Fig. 26: Fichtner found that CO2 reduction can be done at a profit in China.

I was actually surprised to see how cheap it was to reduce CO2 using wind or solar energy. But the real surprise was that just industrial modernisation would produce CO2 reductions as a windfall product. Best of all, strategic energy efficiency will earn the investor twenty dollars per ton of CO2 avoided. This is surely the basis for the astonishing fact that according to official statistics, China has reduced it CO2-emissions during the last three consecutive years while maintaining an impressive economic growth of up to 7% per annum.

Even if not every step of efficiency gains is profitable, the general attitude of eco-efficiency seems to pay. A Swiss-American partnership had lead to the establishment of the Dow Jones Sustainability Index representing the top firms worldwide which have a successful policy of improving eco-efficiency. Look how that paid off on the unforgiving international stock markets. The Sustainability Index had actually a better performance than the benchmark Dow Jones Index:

Fig. 27: Dow Jones Sustainability Index beats the ordinary Dow Jones.

Is that not a very encouraging piece of news? Unfortunately, the scope for profitable eco-efficiency is still rather limited. If we aim at a factor of four, we have to alter the frame conditions so as to make strategic efficiency increases still more profitable.

It can be seen as a perfectly legitimate objective for the state and for the international community to create an atmosphere that is favourable for creating the new industrial revolution. The basic idea is to make resource rationalisation more profitable than labour rationalisation. This has been the philosophy behind the ecological tax reform which has been introduced in most European countries, including Germany. The ideal scenario is one in which prices for energy, water and raw materials increase slowly (e.g. by 3 – 4% annually) so that technical progress can approximately keep pace. Imagine petrol prices increasing by 4% every year and the car fleet becoming 3% – 4% more efficient every year until. Then the fuel price per kilometre will remain almost stable. And your country would have to import much less oil.

Many other measures can be conceived to make resource productivity more profitable. Eco-audits have become very popular in Germany, Japan and elsewhere. The Netherlands through their former government have introduced a rule that pension benefits are tax free as long as the benefits are coming from certified stock portfolios of ecologically committed firms.

In the end I believe that one of the most important driving forces of technological progress is a new vision of how technology could look like in the future. I hope I was able in a very humble way to contribute to this goal.

Back to the alleged Japanese crisis

Let me return to the considerations made at the beginning. The eco-efficiency revolution can theoretically serve as a guideline for Japanese and European industry to return to investment optimism. In this field, it is both responsible and reasonable to go for innovations and massive investments that can shape the technological face of the world.

I also suggest to strengthen the advocates of the public sector again. The weakness of the state is likely to remain. But new allies have appeared on the scene to help the state defend public goods including the environment. It is the civil society NGOs. My last picture shows you in the former caricature form how I see the re-balancing of powers between private goods and public interest.

Fig. 28: NGOs can help the state re-establish the balance between public and private goods.

Let us hope that enlightened business leaders join in re-establishing both that said balance and the optimism that may also help overcome the economic stagnation some of you feel as a heavy burden on your companies and on your country.

Let me at the outset distinguish two different tasks of environmental policy.

• One is pollution control which is predominantly a local and a national activity. The first twenty years of environmental policy in advanced industrial countries were almost exclusively devoted to pollution control and to set standards. Since that time, most environmental professionals both in the public and private sectors deal with pollution control.
• The other task of environmental policy relates to global and long-term challenges such as climate change, biodiversity losses and unsustainable lifestyles. This is rather a new field of concern and is still in its conceptual phase regarding policy making.

Environmental fiscal reforms can work in both arenas. But if one fiscal instrument is successful in one of the two, it does not necessarily follow that it is applicable to the other as well.

For pollution control, pricing instruments abound and have greatly helped cleaning up the environment. A typical case has been the waste water charge the revenues of which were used to finance water purification installations. This system of charges is in use in most OECD countries and has been highly successful environmentally. It never was very controversial. It fully conformed with the polluter pays principle and it had the attraction that he who applied prevention measures in his factory was freed from the charge.

In a wider sense the same applies to user fees, refund systems, violation penalties and tradable emission permits for classical pollutants such as SO2 or NOx They too met with rather little public resistance when introduced.

Let me not lose more time on this subject because we would all agree very soon that prices work well to reduce classical pollution. It remains doubtful if charges on pollutants can be seen as “environmental fiscal reform”.

Let me instead turn the attraction to the other subject, of long term and global environmental problems, notably the greenhouse effect and life style changes. Here, I suggest, is the most important field for environmental fiscal reform.

Let me at this juncture mention one major difference between the two fields of concern. For classical pollution control you could say it is good to be rich so that one can afford costly pollution control. Or, with a slightly modified meaning you can quote Indira Gandhi that “poverty is the biggest polluter”. This famous statement goes down extremely well with developing countries, but equally well with traditional business people and other people in the North because it justifies them to go on with traditional growth strategies and claim that this is good for the environment.

The opposite, or nearly, can be observed when we address the greenhouse effect, biodiversity and sustainable life styles. Here clearly prosperity is the biggest polluter.

This is so embarrassing a phenomenon that economists and politicians prefer not to recognise its truth. They hastily invoke the sustainable development triangle which says that economic and social well-being are equally important as a healthy environment. And very soon they return to the comfortable and familiar paradigm of pollution control where economic prosperity was not at all suspicious. You will discover that in their argumentation the environmental corner of the triangle is always classical pollution control. I am afraid, for the time being I have to invite you to be extremely cautious, if you are an environmentalist, when that triangle of sustainability is put forward.

Now comes the shock for us advocates of pricing instruments: In a domain where prosperity is the biggest polluter, all of a sudden, you have to admit that prices are meant to reduce “prosperity”, — at least the kind of prosperity that is causing so much CO2 emissions, land use, traffic and avalanches of materials. If you want to reduce urban sprawl, you have to say that people shouldn’t live in one family homes and commute to work with their cars. You want them to cut their energy and water consumption. You want them to stop buying lots of unnecessary trash goods and having weekend trips to Egypt or Paris and Christmas trips to the Seychelles. Don’t expect anybody, let alone democratic majorities to agree with these objectives.

And yet, having said all this, I remain a staunch defender of ecological fiscal reform for the second set of problems. How can that be?

Well, it is because I am confident that, fortunately for the environment, different modes of prosperity are available. The core of that “sustainable prosperity” is a new universe of eco-efficient technologies. At the Wuppertal Institute for Climate, Environment and Energy we have sketched out the landscape of that new universe. In a book which I wrote together with Amory Lovins, I gave it the simple title “Factor Four”, with the subtitle “Doubling Wealth, Halving Resource Use”.

The book features fifty examples, from automobiles to household appliances, from buildings to logistics, from industrial processes to farming methods, all demonstrating that a factor of four is available in energy or material efficiency.

The factor four universe can be seen as the Promised Land to those who deal with climate change, urban sprawl and biodiversity losses.

But there is a difference again with classical pollution technologies. Waste water treatment technology can be introduced in a matter of five or ten years, depending on the life cycle of the economy’s capital stock. In buildings, it may take fifty years to refurbish the entire stock of houses. The complete renewal of the car fleet may take thirty years. And a reasonable and comfortable reduction of urban sprawl may take a hundred or two hundred years.

“Factor Four” can be seen as the solid rock of technological insights which we need when talking about ecological fiscal reform that works on the second category of problems. If we want to maintain prosperity we should be patient with the existing capital stock.

The long time frame can also be expressed in terms of price elasticity. You would not expect the car fleet to react to a small but sudden price signal. The immediate price elasticity is very low. However, if society knows that energy and other resource prices will go up slowly but for a long time with no hope of their coming down again, companies will strategically invest in resource efficient technologies. Consumer education will make resource efficient behaviour a prime objective. Academic engineers and scientists will target the basics of resource productivity. And public planning will shift priorities towards convenient mass transport, agreeable high-density urban planning and high resource efficiency in public buildings, transport systems and disposal concepts. As a result, the factor of four becomes a realistic perspective for all sectors. In other words, we can expect a high price elasticity in the long run.

Long term price elasticity means that price signals should be mild but predictable. The best of all worlds would be a political all-party agreement over thirty or fifty years to raise prices for scarce resources in very small and predictable steps, preferably in steps so small that technological progress can keep pace.

Please note that I am talking about a price corridor, not a taxation corridor. Taxes or other instruments would be used to stay inside the price corridor. In this ideal case, the monthly bills for petrol, electric power, water, space or even virgin raw materials remain stable. On average, the population would not suffer any losses in their lifestyles.

If the fiscal revenues from this operation go into reducing indirect labour cost, you would expect positive effects on the labour markets. And compared to business as usual scenarios, you would see human labour services becoming gradually cheaper, i. e. more affordable for the clients of that labour.

So much for the ideal world. I felt it was necessary to talk about the ideal world in order to provide orientation in this conflictual theme of price signals on the basic commodities of modern life.

Let me now very briefly address some of the practical problems.

At a conference in Brussels, four weeks ago, the European Environmental Bureau (EEB) presented an EU-wide campaign on fiscal measures for the environment. At its core, the demand was to have ten percent of all taxes to be environmental and to make the operation fiscally neutral, ie not to increase the overall tax burden.

The EEB’s campaign also asked rapidly to abandon all perverse subsidies. These subsidies, however, are consistently targeted at politically influential parts of the electorate. Transport subsidies in particular enjoy extremely strong support not only from the immediate beneficiaries but also from the automobile and aircraft lobbies. Hence, one would not expect subsidies to disappear soon.

Let me say a practical or political word about the price corridor that I am asking for. It is, let me admit it, highly unrealistic in our days. It requires two unusual things at once: a fiscal policy that flexibly responds to world market signals, and an all-party consensus in one area, which is perhaps the favourite battlefield for political parties. Also, it should be said that the price corridor it not easily attained with emission trading and other pure market instruments. An adjustment mechanism may have to be introduced to avoid brutal jumps that can occur in the course of free market fluctuations.

During the Brussels conference, Dr. Iannis Paleocrassas mentioned that as Greek Minister of Finance he had introduced a fuel tax flexibly responding to world market fluctuations. This is an extremely encouraging example.

A few days after the conference, the coalition agreement was adopted between SPD and Greens in Germany. It reaffirmed the existing energy tax escalator and foresees a general review by 2004 of the green fiscal reform, with a view to potentially develop it further and more comprehensively. A few steps to reduce tax rebates for fiscal year 2003 are now in the pipeline and will hopefully be adopted next week.

If the public is convinced that this gentle price corridor is a fair deal and the best guide rail to the Promised Land, it becomes increasingly more plausible for political parties to go for it.

This then brings me to my concluding remark. It is essential that we create a strong vision of what is necessary to avoid disasters from fossil and nuclear energy use, from rapid biodiversity losses and from resources. If that vision also contains a realistic and agreeable strategy of how to get from here to there, you will have the people behind you.

Let me at the outset distinguish two different tasks of environmental policy.

• One is pollution control which is predominantly a local and a national activity. The first twenty years of environmental policy in European countries were almost exclusively devoted to pollution control, and the role of the European Community – later Union – was chiefly to set standards that aimed at harmonising national pollution control legislation, and that more of environmental professionals both in the public and private sectors deal with pollution control.
• The other task of environmental policy relates to global and long-term challenges such as climate change, biodiversity losses and unsustainable lifestyles. This is rather a new field of concern and is still in its conceptual phase regarding policy making.

Prices can work for the environment in both arenas. But if one pricing instrument is successful in one of the two, it does not necessarily follow that it is applicable for the other as well.

For pollution control, pricing instruments abound and have greatly helped cleaning up the environment. A typical case has been the waste water charge the revenues of which were used to finance water purification installations. This system of charges most widely used in the Netherlands but also in all other EU countries was highly successful environmentally. It never was very controversial. It fully conformed with the polluter pays principle and it had the attraction that he who applied prevention measures in his factory was freed from the charge.

In a wider sense the same applies to user fees, refund systems, violation penalties and tradable emission permits for classical pollutants such as SO2 or NOx They too met with rather little public resistance when introduced.

Let me not lose more time on this subject because we would all agree very soon that prices work well to reduce classical pollution. Nevertheless, if the EEB wants to document the findings of this conference, I suggest to add an expert paper by an environmental economist on many successes and a few failures.

Let me instead turn the attraction to the other subject, of long term and global environmental problems, notably the greenhouse effect and life style changes.

Let me at this juncture mention one major difference between the two fields of concern. For classical pollution control you could say it is good to be rich so that one can afford costly pollution control. Or, with a slightly modified meaning you can quote Indira Gandhi that “poverty is the biggest polluter”. This famous statement goes down extremely well with developing countries, but equally well with traditional business people and other people in the North because it justifies them to go on with traditional growth strategies and claim that this is good for the environment.

The opposite, or nearly, can be observed when we address the greenhouse effect, biodiversity and sustainable life styles. Here clearly prosperity is the biggest polluter.

This is so embarrassing a phenomenon that economists and politicians prefer not to recognise its truth. They hastily invoke the sustainable development triangle which says that economic and social well-being are equally important as a healthy environment. And very soon they return to the comfortable and familiar paradigm of pollution control where economic prosperity was not at all suspicious. You will discover that in their argumentation the environmental corner of the triangle is always classical pollution control. I am afraid, for the time being I have to invite you to be extremely cautious, if you are an environmentalist, when that triangle of sustainability is put forward.

But now comes the shock for us advocates of pricing instruments: In a domain where prosperity is the biggest polluter, all of a sudden, you have to admit that prices are meant to reduce “prosperity”, – at least the kind of prosperity that is causing so much CO2 emissions, land use, traffic and avalanches of materials. If you want to reduce urban sprawl, you have to say that people shouldn’t live in one family homes and commute to work with their cars. You want them to cut their energy and water consumption. You want them to stop buying lots of unnecessary trash goods and having weekend trips to Malaga and Christmas trips to the Seychelles. Don’t expect anybody, let alone democratic majorities to agree with these objectives.

And yet, having said all this, I remain a staunch defender of pricing instruments also for the second set of problems. How can that be?

Well, it is because I am confident that, fortunately for the environment, different modes of prosperity are available. The core of that “sustainable prosperity” is a new universe of eco-efficient technologies. At the Wuppertal Institute for Climate, Environment and Energy we have sketched out the landscape of that new universe. In a book which I wrote together with Amory Lovins, I gave it the simple title “Factor Four”, with the subtitle “Doubling Wealth, Halving Resource Use”.

The book features fifty examples, from automobiles to household appliances, from buildings to logistics, from industrial processes to farming methods, all demonstrating that a factor of four is available in energy or material efficiency.

The factor four universe can be seen as the Promised Land to those who deal with climate change, urban sprawl and biodiversity losses.

But there is a difference again with classical pollution technologies. Waste water treatment technology can be introduced in a matter of five or ten years, depending on the life cycle of the economy’s capital stock. In buildings, it may take fifty years to refurbish the entire stock of houses. The complete renewal of the car fleet may take thirty years. And a reasonable and comfortable reduction of urban sprawl may take a hundred or two hundred years.

“Factor Four” can be seen as the solid rock of technological insights which we need when talking about pricing instruments that work on the second category of problems. If we want to avoid attacking prosperity we should be patient with the existing capital stock.

The long time frame can also be expressed in terms of price elasticity. You would not expect the car fleet to react to an abrupt price signal, unless it is a brutal signal. However, if society knows that energy and other resource prices will go up for a long time with no hope of their coming down again, companies will strategically invest in resource efficient technologies. Consumer education will make resource efficient behaviour a prime objective. Academic engineers and scientists will target the basics of resource productivity. And public planning will shift priorities towards convenient mass transport, agreeable high-density urban planning and high resource efficiency in public buildings, transport systems and disposal concepts. As a result, the factor of four becomes a realistic perspective for all sectors.

Long term price elasticity means that price signals should be mild but predictable. The best of all worlds would be a political all-party agreement over thirty or fifty years to raise prices for scarce resources in very small and predictable steps, preferably in steps so small that technological progress can keep pace.

Please note that I am talking about a price corridor, not a taxation corridor. Taxes or other instruments would be used to reach the price corridor. In this ideal case, the monthly bills for petrol, electric power, water, space, virgin raw materials remain stable and on average the population is not suffering any losses in their lifestyles.

If the fiscal revenues from this operation go into reducing indirect labour cost, you would expect positive effects on the labour markets. And compared to business as usual scenarios, you would see human labour services becoming gradually cheaper, i. e. more affordable for the beneficiaries of that labour.

So much for the ideal world. I felt it was necessary to talk about the ideal world in order to provide orientation in this conflictual theme of price signals on the basic commodities of modern life.

Let me at the end very briefly address some of the practical problems.

First, with reference to the EEB’s campaign motives and targets, let me clearly say that I support them. It will be, however, extremely difficult with regard to reducing internal farm subsidies; it may be possible, however, to reduce export subsidies of farm products. It is reasonable to demand ten percent of all taxes to be environmental and to make the operation fiscally neutral, ie not to increase the overall tax burden.

Regarding the time frame, it is EEB’s right to ask for rapid results, but as a politician I can tell you that our machinery works rather a bit slower. Perverse subsidies too are difficult to remove. They are consistently targeted at politically influential parts of the electorate. Transport subsidies in particular enjoy extremely strong support not only from the immediate beneficiaries but also from the automobile and aircraft lobbies. Moreover, they tend to increase economic turnover which politicians call growth even if it does not contribute to any quality of life. But it is turnover, not quality of life that creates jobs.

Let me say a practical or political word about the price corridor that I am asking for. It is, let me admit it, highly unrealistic in our days. It requires two unusual things at once: a fiscal policy that flexibly responds to world market signals, and an all-party consensus in one area, which is perhaps the favourite battlefield for political parties. Also, it should be said that the price corridor it not easily attained with emission trading and other pure market instruments. An adjustment mechanism may have to be introduced to avoid brutal jumps that can occur in the course of free market fluctuations.

On the other hand, if the public is convinced that this gentle price corridor is a fair deal and the best guide rail to the Promised Land, it becomes increasingly more plausible for political parties to go for it.

This then brings me to my concluding remark. It is essential that we create a strong vision of what is necessary to avoid disasters from fossil and nuclear energy use, from rapid biodiversity losses and from resources. If that vision also contains a realistic and agreeable strategy of how to get from here to there, you will have the people behind you.

Further information about the Conference and the EEB can be found on the EEB’s website.

The World Summit on Sustainable Development (WSSD) is the third event in a row.

The first was the UN Conference on the Human Environment, Stockholm, 1972. In its wake, the UN Environment Programme, UNEP, was founded in Nairobi, and some UN agencies made some moves towards an ecological significance of their programmes. Ten years later, a meeting was held to assess progress since Stockholm and ended in disappointment. Continuing deterioration of the environment was reported chiefly in the developing countries. As one consequence, the World Commission on Environment and Development was created to study the reasons for that lamentable state of affairs, and Dr. Gro Harlem Brundtland, the Norvegian Prime Minister was appointed Chairperson. After three years of intensive work, the Commission published its report which was submitted for discussion at the UN General Assembly in 1997. As a result, the UN decided to convene another UN Conference, this time on Environment and Development, to be held in Rio de Janeiro in 1992.

The Rio de Janeiro “Earth Summit” was the second in the series of UN conferences. It had three major results: The Framework Convention on Climate Change (FCCC), the Convention Biological Diversity (CBD) and Agenda 21 with its fourty chapters. Agenda 21 was seen by many observers as a prescription leading – if properly applied – to sustainable development, a term already found in the Brundtland Report. Another five years later, the UN General Assembly held a special session in New York with a view to look back and assess progress made since Rio. Once again, the assessment was rather depressing from the point of view of the environment, and once again the UN decided to hold major conference, this time called World Summit on Sustainable Development, in Johannesburg, South Africa, in September 2002.

It is difficult to avoid the impression that UN conferences and reports have not been able to slow down let alone stop or revert the destructive trends. To be sure, pollution control has made major progress in the OECD countries. But then pollution is no longer the main ecological concern.

• Global warming seems to go on unmitigated. The Intergovernmental Panel on Climate Change fears that the added greenhouse effect might lead to a rise in average temperatures by some 1.4°C to 5.8°C during the 21st century. This could theoretically have disastrous effects on world agriculture and potentially on the global sea water table. If we want to halt this trend, it would be wise to stabilise CO2 concentrations at preindustrial or, less ambitious, at 1990 levels. This, however, would mean to reduce world wide CO2 emissions by at least 50 percent. Development aspirations, however, rather point at a doubling of CO2 emissions.
• Biodiversity losses have hardly slowed down; some 50 plant or animal species are said to become extinct every day! The major cause seems to be land conversion for civilisational use. One way of measuring this land use was given by William Rees and Matthis Wackernagel as the “ecological footprint”. It represents the direct and indirect land use for living, farming, clothing, transport, industry, recreation, energy etc. OECD countries have typical per capita footprints sized 4 hectares. This leaves most OECD countries too small to accommodate all of their footprints. They therefore have to export much of those footprints to less populated and less area-demanding countries. To accommodate six billion OECD type footprints we would need at least two planets earth. As we have only one, we should reduce OECD footprints at least by a factor of 2, — under the plausible assumption that developing countries have equivalent rights and aspirations regarding wealth and well-being.

Both trends and challenges have a massive bearing on Agenda 21 and the perspectives of sustainable development. If we need to reduce both CO2 emissions and ecological footprints by a factor of two at least while simultaneously aspiring at least to double world-wide wealth, we seem to be confronted with the need to perform at least four times more efficiently with the use of natural resources.

Fortunately, this goal it not as outlandish as it may sound at first. Amory and Hunter Lovins have coauthored a book with me, “Factor Four” which features fifty examples of a fourfold resource productivity. Automobiles can do 150mpg, cooling systems can do with 25% of today’s typical electricity consumption. Buildings can be designed for close to zero external energy input. Farm produce can be made with one quarter of the typical European energy inputs. Materials can be saved by large factors using re-manufacturing techniques. Water can be used four times more efficiently than today in many industrial, agricultural and private uses.

In addition, energy and materials used can be ecologically optimised as is already happening in several countries. Renewable sources of energy are a booming industry in many European countries. And materials can be selected to be perfectly recyclable.

Prices for the use of environmentally scarce resources should be gradually moved upwards so as to create an incentive for introducing “factor four-technologies”. An ecological tax reform or tradeable permits for resource use should be seen as chief candidates for instruments leading to that goal. Both can be designed in a socially and economically acceptable way. Tax-caused price increases can be tied to the pace of progress in average resource productivity.

Aggressive strategies to invcrease resource productivity may show the way for a true harmonisation of environmental and developmental goals thus ending the ecological frustrations we have experienced since the 1972 Stockholm Conference.

On the other hand, we are already now overexploiting the earth. Just to stabilise carbon dioxide concentrations, we would need a reduction of annual carbon dioxide emissions by more than fifty percent. Similarly, ocean fishing should be cut in half. We seem to loose some fifty animal and plant species every day. To stop this trend, we ought to radically reduce land conversion. It is fair to say that we should reduce the consumption of natural resources by roughly a factor of two.

Fig. 1: The daily toll of environmental destruction.

Doubling wealth while halving resource use, that is quite a challenge. The answer could be quadrupling resource productivity. In a book co-authored by Amory Lovins and Hunter Lovins, “Factor Four” (Earthscan, London 1997) fifty examples of quadrupled resource productivity are featured.

Fig. 2: Factor Four was translated in many languages.

My friend Friedrich Schmidt-Bleek goes considerably further and suggests to increase resource productivity tenfold: Factor 10 Institute.

If you are interested in the factor four agenda, have a look at some of my papers in this field. You may as well visit the Wuppertal Institute’s factor four homepage, administered by Raimund Bleischwitz.

My environmental interest go beyond the factor four agenda. In October 2002 I was appointed Chairman of the Bundestag’s Environment Committee. Here we are working on

• The adaptation to German laws of EU environmental directives,
• The interface of environment and agriculture,
• The promotion of renewable sources of energy,
• International environmental agreements,
• Commenting draft legislation from other policy fields.

Introduction

This piece was written by a European and an American both deeply engaged in efforts to moderate global warming, and each of whom has lived in both Europe and the United States. We give a perspective on the present situation regarding climate change in Europe; a parallel perspective on the situation in the U.S.; and then close with a series of recommendations and policy opportunities that should be on the agenda of the transatlantic partnership, but which reflect the reality that Europe is the leading geopolitical unit today in defining and mobilizing global progress toward a regime of carbon limits that holds out the possibility of avoiding the most catastrophic consequences of global warming.

I: Grim facts on climate change

It has become clear to climate scientists that the carbon emission targets set by the Kyoto Protocol were not nearly ambitious enough to “prevent dangerous anthropogenic interference with the climate system”, as stated in Article 2 of the UN Framework Convention on Climate Change (FCCC).

The Arctic Climate Impact Assessment (2004) was perhaps the most powerful wake-up call of the past few years. It showed a picture of Greenland’s fresh water cover in summers 1992 and 2002 with the area of the latter being easily four times larger than the former and being nearly half the size of Greenland itself. Mighty vertical water currents tunnel down into the ice and appear to be lubricating the rocks on which the ice masses are sitting, thus accelerating the rate at which they move towards the sea beyond that which had been previously estimated.

Fig. 1: Freshwater lakes on Greenland during Summers 1992 and 2002.

This Assessment and other facts served as the scientific basis for the November, 2006 Review on the economic consequences of addressing or failing to act on climate change published by Sir Nicholas Stern, former chief economist of the World Bank. This report had been commissioned by British Prime Minister Tony Blair and Chancellor of the Exchequer Gordon Brown.

The Review suggests that early action to reduce greenhouse gas emissions would be much cheaper than originally assumed, and that delaying action will risk horrendous damage that could amount to as much as 20 percent of world GDP.

Climatologists tend to converge around the conclusion that global warming of an average of 2°C above pre-industrial levels should be seen as the threshold beyond which the anthropogenic interference with the climate system would become “dangerous”, to quote Article 2 of the FCCC.

All this information was available at the FCCC’s 12th Conference of the Parties in Nairobi in November, 2006. One had hoped that a post-Kyoto architecture could be negotiated but nothing of the kind happened. Nairobi was basically a bureaucratic gathering with no visible political initiative, although some progress was made on policies aimed at discouraging deforestation and laying the groundwork to bring emissions from deforestation under the post-Kyoto framework.

The EU had nothing to contribute to the coming debate on post Kyoto.

II: The EU’s bumpy learning phase

Nevertheless, the EU considers itself in the vanguard of climate policy. It was instrumental in launching the FCCC, which was adopted in Rio de Janeiro. Five years later, at the third Conference of the Parties of FCCC in Kyoto, the EU was one of the major players and ultimately the decisive one, in urging adoption of the Kyoto Protocol.

And finally, it was the EU which adopted the first international regime of carbon trading, through its Emissions Trading Scheme, ETS (Directive 2003/87/EC).

The first phase of the ETS, from 2005 to 2007, intended as the “learning phase”, ends this year. Some lessons can certainly be drawn from this learning phase. The EU had seen economic growth and growth in carbon emissions since Kyoto’s adoption, leading to demand for higher volumes of carbon allowances than appeared available in 2003. Therefore despite the political decision, taken under heavy influence from the major emitters, to allocate the allowances free of charge, allowances had a positive price from the start.

Fig. 2 shows the development of the price per ton of CO₂ emissions. The market price underwent a conspicuous collapse in May, 2006, due to the leaking of research data that major emitters were sitting on large quantities of unused allowances. At the time of the initial allocation they had claimed many more allowances than they actually needed.

Fig. 2: ICE-ECX Carbon Financial Instrument Futures Contract

What was more irritating than permit hoarding, not least to end-use consumers, was that some power utilities, notably in Germany, raised electricity prices in proportion to the market value of the allowances that they had obtained free of charge in the first place.

The power utilities argued that for every marginal kilowatt-hour generated above earlier production levels, additional costs would accrue in proportion to the permit prices. This led to calculations of horrendous marginal consumer prices above 1.000 Euros per ton of CO₂ emitted (Schlemmermeier and Schwintowski, 2006).

Ironically, most of the major emitters flourished tremendously after the introduction of the ETS, although the causes of this prosperity are complex. Electric utilities benefited from acquiring an oligopoly position a few years after market liberalization, while non-ferrous metals producers benefited from rising commodity prices.

Another irritating effect came in in recent months. Under the Kyoto Clean Development Mechanism (CDM), emitters were allowed to trade some of their obligations outside Europe. Their favourite place were China and India, discovering that reducing Chlorofluorocarbons (CFC’s) was valued very high on the scale of greenhouse gas emissions because their Global Warming Potential (GWP) is several thousands times higher per kilogram than that of CO₂.

To meet the phase out date of 2010 under the Montreal Protocol, developing countries are quite willing to reduce their production and stocks for good money from Europe. As the reduction of such substances is much cheaper per unit of GWP than CO₂ emissions reduction this trade is profitable both for the developing countries and the EU firms in need of reducing greenhouse gas emissions. This bargain is the main reason for the continued fall of prices for carbon emissions permits, as seen in fig 2. The bargain is nevertheless irritating because it weakens the incentive to reduce coal, oil and gas intensity in Europe, while China and India swiftly substitute phased out CFS’s with HCFC’s, notably with HCFC-22, the production of which results in emissions of trifluoromethane (HFC23), as an unwanted by-product that is a super greenhouse gas with a GWP 11,700 times more than CO₂.

The general impression in the European public is that not all went well with the “learning period” of the ETS. It will be politically difficult to repeat the free allocation of emission permits next time, and more voices are already being heard suggesting an auction of the allowances for the next phase.

The second phase of the ETS runs from 2008 to 2012, coterminous with the Kyoto Protocol. The EU intends to deliver the commitments assumed in the Kyoto Protocol.

Although it seems uncertain whether the ultimate target of an eight percent emissions reduction from levels in 1990 will be reached, the EU has performed far better in curbing greenhouse gas emissions than nearly all other Kyoto signatories. EU performance has also outpaced the US and Australia who have not ratified Kyoto and have had drastic increases in greenhouse gas emissions since 1997.

Post-Kyoto initiatives of the EU

It is clear now that Kyoto was just the first step toward a robust, global regime of carbon limits.

Everybody seems to agree that the post-Kyoto regime will have to be a lot more ambitious than Kyoto itself.

Greenhouse gas emissions will have to be reduced to at least 50% of expected business-as-usual levels if greenhouse gas concentrations are to be stabilised at a level low enough to keep global warming within roughly 2°C. Recent work (Vattenfall & McKinsey) suggests that stabilizing the climate at 450 ppm CO₂ by 2030 is doable and affordable if we start very soon. This goal is roughly compatible with holding the warming increase to 2O°C.

Many believe that eventually we will have to get beyond that goal and reduce emissions to 80% below today’s level.

What can be done on the European side to reach this goal? Essentially three strategies are available and have to be combined:

• Increasing energy efficiency;
• Increasing the use of fossil-free energy; and
• Reducing the amount of carbon dioxide being released into the atmosphere.

The EU has been fairly cautious on energy efficiency.

The energy efficiency directive, 2006/32/EC (16 May 2006), requires member states to draw up national action plans to achieve 1% yearly energy savings in the retail, supply and distribution of electricity, natural gas, urban heating, and other energy products including transport fuels. The 1% target, however, is only indicative. The national action plans will need approval from the Commission and will be reviewed every three years, but there are no sanctions whatsoever. The process will be spread over nine years, starting in January 2008, although the first national efficiency action plans are due for submission on 30 June, 2007. The European Parliament had demanded binding targets but member states killed that proposal during a Council meeting in 2005.

On renewable energies, the EU is more progressive.

Its 1997 White Paper contained a commitment to double renewable energy supplies to 12% by 2010 from 6% in 1998. The EU seems to be nearly on track to reach this goal, not least because of the pioneering roles of Denmark, Austria and Germany and the adoption in Spain of the German model of feed-in tariffs for electricity from renewables that is piped into the power grid.

In January, 2007, the Commission published “An Energy Policy for Europe” (COM (2007) 1 final). Its most specific change against earlier policies is the proposal for a binding target for biofuels to reach 10% of vehicles fuel by 2020, twice as much as proposed in earlier documents. This ambitious goal seems like an attempt also to join the USA in reducing dependence on imported oil. However, it immediately met with fierce opposition by ecological and North-South NGO’s hinting at big dangers resulting from diverting land from food and from the last remaining nature reserves.

The big contribution towards an ambitious climate policy seems to be intended to come from a new initiative to aggressively promote and spread “Clean Coal Technologies”.

Important steps were the increase of plant efficiency, chiefly by combined- cycle coal and gas technologies, some CHP (combined heat and power) and, according to a new EU Communication, a massive drive towards CO₂ capture and storage (CCS) in coal-based power generation. Bringing CCS to commercial viability in coal-fired power generation would pave the way to possible applications in combustion processes using other fossil fuels, notably gas. The new name of this game is “Sustainable Fossil Fuels” in power generation.

CO₂ capture and storage is perhaps the strongest incentive for speeding up the introduction of the Integrated Gasification Combined Cycle (IGCC) because that technology involves the automated separation of CO₂ as well as of sulfur and also allows the “syngas” from the gasification process to be used as feedstock for the hydrogen economy. However, all this comes at a cost, and many utilities, chiefly in non- Kyoto states such as the US, say that present market conditions leave IGCC non-competitive with conventional coal burning power plants.

Nevertheless, in light of the reality that coal is going to be burned one way or the other in China, India, other developing countries, and the U.S., and in the absence of an aggressive strategy on efficiency and renewables, CCS and IGCC may turn out to be lifelines for Europe and the world in curbing the release into the atmosphere of carbon dioxide.

Efficiency is more promising

It would be a lot more attractive, however, to have a well- orchestrated strategy to increase energy productivity.

On a macroeconomic scale, it is generally possible to extract at least four times, and in many sectors ten times, as much added value from one unit of energy than is presently achieved, be that unit kilowatt-hours, barrels of oil or gigajoules (Weizsäcker et al, 1997, Lovins et al 2005). The process may take 40 years but that is also the typical life-span of power plants. In addition, we are facing a new wave of decisions on the next generation of power supplies in Europe. Building too many dinosaurs now will make it virtually impossible for the next generation of politicians to shut them down or convert them without huge economic disruption.

The German grand coalition government has made energy efficiency its top priority and is trying during the twin Presidencies of the EU and G8 to popularize the concept.

III: The US and Climate Change

After years of dragging their feet, 2006 – 2007 will be seen as the years when Americans finally made up their mind that global warming was a serious crisis that required action.

American science helped to identify and highlight this issue in the 1980’s and 1990’s, and American NGO’s formulated the basic cap-andtrade policy model that underlies Kyoto and the ETS. American political timidity in the 1990’s and then outright obstructionism under the second President Bush slowed global progress on this issue. Fortunately, Europe took the lead – and did so relatively vigorously, sensibly, and with a careful eye to keeping the door open for the U.S. to rejoin the international process when it could.

That day is now near, and it will become a lot nearer when the US Congress enacts its own national cap-and-trade system.

There is a good chance that this will happen during this Congressional session, which means in the 18 months before the next Presidential campaign begins to paralyze the rest of the political process; and there is a good likelihood that if the law that is enacted is centrist and solid, President Bush will not veto it.

What has happened in the US to make this possibility imminent? Several things at once:

• The science became stronger, more visible, and more urgent.
• Business leaders, particularly the multinationals, came to understand that action on global warming was an imperative and began to remove the silent veto they exercise in American politics. General Electric, Wal-Mart, DuPont and others reflected a broad, silent change in mainstream American business attitudes toward global warming when they came out in favour of a mandatory national carbon cap.
• Thoughtful Americans noted that almost all of its allies with the quixotic exception of Australia, whose stance on this issue was quaint but not politically significant, were marching in the opposite direction.
• Many conservative evangelical Christian leaders decided that action on global warming was not only congruent with, but required by, their doctrinal beliefs.
• Former Vice-President Al Gore’s powerful movie, An Inconvenient Truth, ratcheted up the sense of urgency among those American opinion leaders already concerned about global warming. Intensity and urgency were the critical elements that had been missing in the American political discourse on global warming.
• The Democrats taking control of Congress by a thin margin now forces all stakeholders to reconsider their assessment of what may or may not be possible in the new Congress. That reassessment is by no means complete.

IV: The Impact on the Transatlantic Relationship

There are two pre-eminent reasons why climate change is both a critical and a formative issue for the most important geopolitical relationship in the world – that between Europe and the U.S.

The first reason climate change is a critical issue in the transatlantic partnership is because attitudes toward global warming specifically and environmental issues generally have their roots in fundamental values, life-styles, consumer habits and political outlooks.

It is one thing to share a broad consensus on democratic values and the market system, modulated to different degrees by state regulation or intervention; we grumble about each others’ political institutions and economic policies, but we do not differ fundamentally. But it is quite another thing for the European end of the transatlantic partnership to feel that environmental concerns are a bedrock and enduring priority for its own governments and a standard by which to judge the American government; and for Americans to feel vaguely that environmental issues constitute only one of many desirable agendas that need to be taken into account, and that on “green issues” the Europeans are “over the edge”. This rift becomes more serious as both ends of the partnership begin to understand that the “the environment” is really about “the economy, stupid.”

The second reason climate change is a critical and formative issue in the transatlantic relationship is because ultimately global warming requires that the Western industrial pattern, now imitated or imposed in virtually every part of the globe, undergo a carefully managed, full-scale, and relatively rapid transition to a low-carbon economy.

The process of decarbonizing our energy generation, our goods production, and our transportation systems on this planet is a task that is both daunting and imperative. It is one that will remain high, perhaps paramount, on our agenda and our children’s agenda for as long as they and we are alive.

What America must do is reasonably clear.

The US must pass a national carbon cap, with no “escape hatches” or other vitiating gimmicks.

It must then join Europe’s preliminary and fragile dialogue with China and the other giant economies of the South to build a bridge over which the US, China, Brazil, India and others can walk to join the young international regime of carbon limits.

In addition to these basic steps the US should, in concert with Europe, work on a plan of “carrots and sticks” in the trade area that will encourage other countries to join an eventual global carbon-reduction regime.

Such a plan should be linked to the evolving world trade system — for example, after a certain date requiring countries that have not taken a cap and joined the global carbon-reduction regime to accompany exports with certified carbon allowances to offset the CO₂ emissions involved in their manufacture. Measures of this type will in any case be necessary for domestic political purposes in the US and Europe if they are to support a serious global regime with the ambitious measures necessary to avoid the worst consequences of global warming.

These steps are simple to describe but not easy politically for the US to adopt. Following this course will, however, allow the US to participate constructively in the formation of a successor to the Kyoto Protocol, and will also serve to align once more the stances of the two partners in the transatlantic partnership in regard to climate change.

We suggest that Europe, as the transatlantic partner that in fact presently leads this process, should consider even bolder steps.

What might an American who has lived in and admires Europe advise Europe to do in this context? The following ideas will strike some European observers (though surely not the European co-author of this piece!) as unnecessarily bold. The opposite is true; if anything, they are not bold enough.

• Europe should continue to advance and improve the European Trading System. This is the world’s only full-fledged carbon capand- trade system. If it is weakened rather than strengthened; if it does not develop strong and impartial enforcement mechanisms; if it becomes a political horse-trading where favoured industries can get cushiony allowances; or on the other hand if it pushes too far too fast and causes unnecessary job loss and economic dislocation – any of these “ifs” could slow down or imperil the development of a wider post-Kyoto global carbon-limits regime. The ETS must grow in rigor and solidity. It need not set quantitatively more ambitious CO₂ reduction targets at this time. Both business and the public must be able to look at the ETS and say: “Yes, it is working, it is getting stronger, and we can live with it. This is the path of the future.”
• Europe should expand and intensify its dialogue with China. In the end only China’s self-interest will draw it into a global agreement. But the forces in China that want to do that need the exposure, the experience, and the analytic information necessary to make their political case domestically. An early objective should be discussion between the EU and China about an EU-supported financing scheme to make China’s next 100 coal plants “carbon-neutral”, with continuation of the scheme beyond 2012 conditional upon China joining the international system of carbon-restraints (which of course it will influence in large measure). Tony Blair, to his credit, started this process. Germany will now have to play a lead role in continuing and expanding it.
• The EU should take the bold and innovative step of inviting selected sub-national American political jurisdictions to join the ETS on a limited basis. That would include the state of California; the New England states that have limited CO₂ emissions from utilities; a forthcoming initiative of five Western US states to establish a regional carbon cap; and a growing number of other states or regional groupings that are now considering carbon limitations of various kinds. The participation should be limited in the amount of trading allowed so that it does not distort the European system, and the talks preparing this will necessarily be difficult because of the thorny American legal issues it will raise. But moving in this direction is important for creation of an international system, and its effect on American politics will be positive. The worst thing would be for Europeans to conclude that in order to “keep America in the game” they must move more slowly. On the contrary, the only thing that will “get America in the game” is to keep the pace of movement steady and serious.

• While one of the greatest virtues of cap-and-trade systems is that it treats all emissions as equal and drives economic actors to “hunt” vigorously for the lowest-cost, most efficient ways of reducing carbon, the world-wide stampede to build dirty coal plants is so large, and promises to lock in such a high level of carbon emissions, that special attention is required. The present EU discussion on when and how to seek carbon-neutral fossil fuel energy generation is the single most important debate on this issue, and if Europeans can drive it to a bold and successful conclusion, this will have enormous impact on both the U.S. and China. Recent work in many quarters, including a notable study on the costs of global abatement by Vattenfall and McKinsey, concludes that “dirty coal” can be tamed in terms of global warming if we move firmly and soon. Only Europe is now capable of defining and implementing that vital new direction.

V: The Transatlantic Partnership to Combat Climate Change

We divide our list of policy choices and opportunities that now lie before the transatlantic partnership in the area of climate change into three categories.

The first category consists of directions and adjustments that will help make it attractive for those countries now outside the system of Kyoto carbon reductions to participate in such a system. We call this category “carbon diplomacy”.

The second category, “slow and steady”, contains policies that contribute to climate stabilization, and which must be pursued steadily so that the costs of low-carbon systems come down and new technologies are refined, but in such a way that the they do not drive a country’s or region’s marginal cost of energy generation or goods production far outside the relevant global marginal cost curves. These policies, however, both help lay the ground for, and contain the potential for rapid acceleration within, a successor global carbon-limit regime once that is put into place.

The third and final category we call “win/win”: they are policies that both contribute to climate stabilization and increase the global economic competitiveness of whichever countries adopt them.

Generally, the faster these options are adopted and pursued, the greater the gain, both in greenhouse gas emission reductions and in economic performance. At the present time, Europe and Japan are broadly best positioned to pursue them.

a) “Carbon Diplomacy”

• Modify the ETS to provide quantity-limited “docking stations” so that sub-national jurisdictions such as American, Brazilian, Indian or Australian states and Chinese provinces that “take a cap” could trade a limited amount of allowances on the European carbon market.
• Europe should get on board wholeheartedly with the global effort to develop a system of “Compensated Reductions” under which the rainforest nations can receive credits in the international trading system if they arrest deforestation. (Deforestation accounts for roughly 20% of global greenhouse gas emissions.)
• Europe should expand its dialogue with China on climate and energy security to include:
  • Exploration of a “low-carbon zone” that would provide advantageous financing and low-barrier IP arrangements for the globe’s largest consumer market and its largest provider of goods.
  • Exploration of ways in which Europe could provide financing to cover the marginal debt service costs of making China’s next generation of coal plants carbon-neutral as long as China joins and remains part of a global system of carbon caps.

b) “Slow and steady” options:

• Set energy portfolio standards that require more renewables.
• Make Carbon Capture and Sequestration safe and affordable, and thereby break the back of the coal problem. Europe is presently in a strong position to extend its technological and IP lead in this area. The present internal debate in Europe over whether to require carbon neutrality for all fossil fuel plants by 2020 is one of the most important and exciting discussions currently ongoing in the climate arena, and its outcome will have enormous impact around the world.
• Set more demanding but reasonable carbon reduction targets within the framework of the ETS, but this time with the long time horizons necessary to affect capital investment decisions.

c) Win/win options:

• Sharply accelerating the drive for energy efficiency. Europe is in a position to ramp up its efficiency targets now. The U.S. cannot do so easily on an economic basis without either a national carbon cap or financial incentives that encourage utilities to “sell” efficiency to their customers [2], or both, in place.
• Begin to shift agricultural subsidies from payments for surplus or non-production to payments for carbon sequestration. Agricultural sequestration will be necessary as a “bridging” device over the next quarter century for offsetting carbon emissions from traditional sources until they can be replaced with low-carbon sources. The US and Europe between them pay their farmers several hundred billion dollars per year in counter-productive subsidies for various forms of economically useless behaviour or inactivity. It will be far easier to redirect these politically sensitive subsidy systems than to dismantle them. China, India, the US, Europe, Canada, Brazil and others will all, before we are done, be supporting “carbon farmers” of one sort or another. Designing the terms, institutions and enforcement systems of such a system needs to begin now. Either Europe or the U.S. could take the lead, or they could launch the first “study” phase together as an adjunct to the Doha Round now underway. (As this article goes to press, Europe and the US are working feverishly to find ways to “save” the Doha Round.)
• Begin to set efficiency standards for vehicles and aircraft which sharply increase mileage efficiency, achieve significant net carbon emission reductions, and sharply decrease reliance on imported fuel. (It is possible to have vehicles that will get as much as 500 miles per gallon of imported hydrocarbons). It will be possible with a single set of aggressive transportation policies to modernize the automotive sector, trigger development of a new generation of aircraft that are more efficient and emit less greenhouse gases, and provide increased income for the agricultural sector through national production of low-carbon fuels. Almost all of the world’s major auto companies are multinational, and it makes most sense if Europe, the U.S. and Japan start down this path together. However, any one of the three could begin alone.

Conclusion

In the trade-off between the aggressiveness of the steps required, and the time remaining in which to take them, it is clearly in the interest of humanity to start early and carefully, rather than late and drastically. Europe has grasped this; as of this writing the US is just beginning to awaken to that fact.

Every previous experiment with market-based systems suggests that once we adopt the system and unleash human ingenuity, commercial inertia, financial greed and naked ambition in the service of avoiding climate meltdown, it will happen faster, more easily, and more cheaply than even the shrewdest economists and pundits predict.

However, a difficult and fateful conversation with the large and growing economies of the South remains in front of us.

The one issue on which the US and Europe have no time to lose, then, is to get themselves facing in the same direction and working together once again on this vital issue.

Only in this manner will they be strong enough to insist wisely but firmly upon a set of incentives and constraints likely to make it in the self-interest of the developing countries to join a carbon-reduction framework that will, at last, be truly global. Let us remember that unlike past problems, the brutal reality that underlies the threat of global warming is that either we all succeed in avoiding the worst, or none of us will.
