There's an important discussion going on in the negotiations about developing country action. The fact is that 97% of future growth in global emissions will come from developing countries. So we cannot have a successful global climate change regime without the broad participation of developing countries. The debate that's going on is about how those commitments will be expressed. Will they bound or not in an agreement? How will they be measured, reported, and verified? I think that speaks to some of the debate that's continuing.
The minister and I were in London on the weekend at the most recent meeting of the Major Economies Forum on Energy and Climate, where this continued to be discussed. I think our general sense is that countries are seeking to deal with these issues constructively, but there are some significant questions that remain to be resolved, including what kinds of commitments major developing countries will assume, and under what conditions, in a new global agreement.
