What pleases me most is that sustainable development is on almost everybody's agenda now.

We're either going to save the world or no one will be saved.

We owe at least this much to future generations, from whom we have borrowed a fragile planet called Earth.

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.

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.

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.

I am on the board of corporations who contribute both to environmental problems and their solutions. And I am on the NGO side: the Earth Council and other organizations.
