Climate Change

My right hon. Friend, who knows so much about these questions, is right. We need to agree numbers that are not only scientifically based, but realistic. In retrospect, it is clear that some countries signed up to numbers at Kyoto—I do not know whether they knew that this would be the case at the time—that they have come nowhere close to achieving. The numbers need to be realistic and consistent with the science. Let me say how we get to that agreement. I think that I have made it clear that the formal negotiations have their role, but will not, on their own, achieve success. That is why in June the Prime Minister made proposals on finance, and it is why it is right that the European Union has not treated this like a conventional negotiation—it has not kept its cards close to its chest until 3 am on the last evening and then revealed its finance numbers. We have got to push and we have to be persuaders, and sometimes unilateral action is important, because it drives people forward. I also think that the EU's role in the coming weeks is to use our commitment to go to 30 per cent. as part of a global deal as a way of levering up greater commitments from others. May I briefly say something about the situation in the United States, which is very important? Hon. Members will know that it is, in a sense, key to this deal and the situation is not straightforward at all. I believe that it is still possible that the US will come forward with a clear number at Copenhagen, despite the fact that the Senate Bill may not be through. That is very important, because the risks of failure at Copenhagen and delay are significant; I do not think that this gets any easier the longer we leave it. Thus, I think—we have conversations about this with the United States—that it is important that the US, despite its domestic issues, comes to Copenhagen with a clear set of ambitions and is able to sign up to an agreement. We know that we need the US as part of an agreement and that the biggest flaw in the Kyoto agreement was that the US was not part of it. Just to be clear, we in Europe intend to use our commitments to drive others forward.
