I am a socialist in ideology, a capitalist in methodology.

Don't accept that you can't make a difference. Because if you can't make a difference, you won't make a difference, and if you put a multiplier on that we will continue on an unsustainable pathway.

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

I learn something from criticism because when it comes from sources you respect you always examine it and learn.

One of the things that Ive always thought I would like to do is to develop an environmental index. Then people can measure their own environmental performance on an index as they do in other ways.

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?

I've developed a huge regard for Toyota for its environmental awareness, for its immense commitment to research and development in this field, and for its leadership in developing hybrids which others are now following.
