"We've invested heavily in clean energy research. We believe very strongly that we've improved efficiencies and a whole step range of steps that we can meet and the commitments that we made in Copenhagen and Cancun. And as we move forward over the next several years, my hope is, is that the United States, as one of several countries with a big carbon footprint, can find further ways to reduce our carbon emissions. I think that's good for the world. I actually think, over the long term, it's good for our economies as well, because it's my strong belief that industries, utilities, individual consumers -- we're all going to have to adapt how we use energy and how we think about carbon.
"Now, another belief that I think the Prime Minister and I share is that the advanced economies can't do this alone. So part of our insistence when we are in multilateral forum -- and I will continue to insist on this when we go to Durban -- is that if we are taking a series of step, then it's important that emerging economies like China and India are also part of the bargain. That doesn't mean that they have to do exactly what we do. We understand that in terms of per capita carbon emissions, they've got a long way to go before they catch up to us. But it does mean that they've got to take seriously their responsibilities as well. And so, ultimately, what we want is a mechanism whereby all countries are making an effort. And it's going to be a tough slog, particularly at a time when the economies are -- a lot of economies are still struggling. But I think it's actually one that, over the long term, can be beneficial."
