Thank you.
Gentlemen, there's been some suggestion from some quarters that we don't need to commit to the Canadian targets until after Copenhagen. I'd like your opinion on whether you think that there's any value in that suggestion, or does it make more sense, as I and others in my party have been suggesting, that in order to get a good agreement at Copenhagen, we should be committing—we should have already committed—now to the science-based targets leading into Copenhagen?
