What I can tell my hon. Friend is that we have learned the lessons from the donor conferences of the past where many countries made promises but did not deliver. We believe there needs to be a new architecture and a new framework, within which the money will be collected according to a formula possibly based, we think, on greenhouse gases and emissions combined, and with every country except the least developed of them having to contribute to the pot. That is the way in which we can make a difference, and that is what we are hoping to achieve in the Copenhagen agreement.
