The ability of communities to meet their most basic needs - food, water, energy, sanitation - is threatened by climate change.

National governments alone cannot deliver lasting prosperity without a transformation of social and economic development that seeks to minimise risk and seize the opportunity we have.

A lot of U.S. businesses are really going into the agenda of sustainability, and some are making their own commitments in emissions reductions in their own operations.

We need to really get very serious about a transition toward new and renewable sources of energy.

The risk to cities from climate impacts carries great social and economic cost and, of course, the loss of human lives.

Actually, climate change is really about the wellbeing of people. It is not a very vague concept or a vague problem that is out of our everyday lives. It is actually affecting our everyday lives, and this is the fundamental fact that everybody should keep in mind while working toward a low-carbon society.
