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.

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.

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.
