Europe's situation is a bit different from Canada's. But in Europe you have a wide range of differences in the level of emission reductions that countries are undertaking. As I understand it, under the European Union emissions trading system, the post-2012 regime will be a single regime, and there will simply be an allocation centrally. Therefore, individual country targets under the emissions trading system will arise from the obligations of the regulated facilities.
There are other areas of policy in Europe that relate to energy efficiency goals that may be national. I don't know if there is a similar arrangement that could take place here. I think the critical issue is going to be whether we have effective collaborative action sufficient to achieve our goals and to place us on a pathway towards very deep emission reductions.
