The G8 nations, together with the five major emerging economies of China, India, South Africa, Brazil, Mexico, use almost three-quarters of the Earth's biocapacity - the capacity of the world's ecosystems to produce natural resources and to reduce harmful substances.

What we have at present is a system of loss socialism. Whatever goes wrong is shouldered by the general public and anything that works is privatised. Worshippers of market freedom have suspended the most important economic principle: Risk and liability go hand in hand.

Madame Merkel knows very well that her conservative Christian Democratic Union or CDU, and the CSU, the Bavarian sister party to the CDU, with which it shares power nationally, must change their European policies. The FDP's nationalist-liberal position on Europe is presumably one of the reasons the attempt failed to form a Jamaica coalition government which would have seen the CDU, FDP and Green Party govern together.

Besides Germany, the only countries that don't have speed limits are places like Nepal, where road conditions are so bad that a limit would be beside the point. In other words, it's a little crazy that this is even a topic for debate in Germany.

Countries that work with Europe should feel safer than they would if they worked with non-democratic regimes. Why isn't Europe building infrastructure in Africa instead of leaving it to the Chinese? Why haven't we succeeded in promoting the economic development of our neighbors in the Balkans, instead conceding these countries to growing Russian influence? In an uncomfortable world, we Europeans can no longer sit back and wait for the U.S.A.

But, as environment minister, I am very interested in a thriving German automobile industry, because I can only pay for the rising costs of environmental protection at home and abroad if there are people in Germany with jobs and who pay taxes.

I am certain that the United States next year, under a new president - regardless whether it's Obama or McCain - will present an ambitious program promoting renewable energies and energy efficiency. Europe could quickly fall behind.
