Toyota was the first to put a commercial fuel cell powered car on the road, and I have no doubt that Toyota will continue to be in the front lines in the development of competitive fuel cell vehicles.

What if a small group of world leaders were to conclude that the principal risk to the Earth comes from the actions of the rich countries?... In order to save the planet, the group decides: Isn't the only hope for the planet that the industrialized civilizations collapse? Isn't it our responsibility to bring that about?

A citizen of an advanced industrialized nation consumes in six months the energy and raw materials that have to last the citizen of a developing country his entire lifetime.

Anyone who is seriously interested in me would usually do a little more homework and realise that the extreme criticisms are almost exclusively ideologically based.

The concept of national sovereignty has been an immutable, indeed sacred, principle of international relations. It is a principle which will yield only slowly and reluctantly to the new imperatives of global environmental cooperation. It is simply not feasible for sovereignty to be exercised unilaterally by individual nation states, however powerful. The global community must be assured of environmental security.

Nevertheless, the concept of sustainable development is now known - even amongst those who haven't accepted it - and it's recognized, debated and followed by an increasing number of businesses.

My belief is that the purpose of economic life is to meet the social needs of people.
