Yes, I think there are many spheres of the complex issue of climate change, and Canada is attempting to play a leadership role in each of those. Step one is to pull your weight in terms of reducing emissions, which I feel we are doing, and that's being recognized. The others are to contribute to international processes, which we're doing, and contribute to the efforts of other countries; and you've heard presentations at this committee on climate finance and other things. So we've certainly been engaged internationally, and we're doing our homework at home.
