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.

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

I was with Ted Turner when he came to see Kofi Annan - the Secretary-General of the UN - to announce his decision to put $1 billion to the service of UN projects and programs.

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

I believe we are going to move into a situation where the more effective conferences will be smaller, more specialized, more focused, with occasional large gatherings to get the attention of the larger world.

I am retired from all my official roles, but I am still very active. I have close relationships at the U.N. I don't have any role at the U.N, but I'm still quite cooperative with a number of U.N. activities, in particular to China and that region.

We must, from here on in, all go down the same path... There may not be another chance.
