In my view, there is an urgent need to communicate with the public and help to explain where there is consensus, and where are there doubts about the issues of sustainable development.

Globalization was a deep trend pushed by technology and right ideas, as much as anything else.

The idea that UN commitments should be followed by action is indeed a radical one, especially for the United States, where wilful neglect of its own commitments is the rule.

It's quite possible to arrive in the year 2030 where people are no longer dying of poverty. We could actually help lead a global end-not a reduction, but an end-to absolute poverty...I have always found that a committed, powerful group of leaders, can make a huge difference.

There's a lot of strength in the U.S., but there's a lot of froth also. The froth will blow off. We're going to have to face up to some realities that we're not fully facing up to right now.

The longer you wait, the less fun. If you wait until the bitter end, the whole economy can be destroyed.

I believe myself that there's a great deal more interest and engagement among Americans than our politicians recognize.
