A number of U.S. companies have recently banded together under USCAP, the United States Climate Action Partnership, including GE, Alcoa, Duke Energy. Basically what they're saying is that we need a cap and trade system, we need regulation. I fundamentally believe that given the interdependency of our two economies, we need to make sure we don't harm ourselves and that basically we have a harmonization between us.
That's why I said initially that whatever we do, we have to make sure we move in lock-step, or reasonably in lock-step, so we can learn by having a domestic market, so we can learn by having sectoral targets. In the final analysis, we're going to have to make sure that on a North American basis we have a competitive bloc on which we can act.
