Let me come to that now. From the way things are going, I think it is now inevitable that there will be a price on carbon, and there will be a North American market. I say that because we already see states and some Canadian provinces entering into carbon markets. It is the experience in the U.S. that their federal legislation is very often based on experiments that are carried out at the state level. I think it's inevitable that we will see a price on carbon in North America.
