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.

The combination of population growth and the growth in consumption is a danger that we are not prepared for and something we will need global co-operation on.

The Earth Charter is important as an expression of the commitment of people throughout the Earth to evoke their own deepest moral, spiritual and ethical principles in the task of ensuring a sustainable future for those who inhabit the Earth now and those who will follow us on the Earth.

After all, sustainability means running the global environment - Earth Inc. - like a corporation: with depreciation, amortization and maintenance accounts. In other words, keeping the asset whole, rather than undermining your natural capital.

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

Strengthening the role the United Nations can play...will require serious examination of the need to extend into the international arena the rule of law and the principle of taxation to finance agreed actions which provide the basis for governance at the national level. But this will not come about easily. Resistance to such changes is deeply entrenched. They will come about not through the embrace of full blown world government, but as a careful and pragmatic response to compelling imperatives and the inadequacies of alternatives.

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.
