I don't think about this a lot. I think about how we can get going.
At this point, I think it would be very good for the rich countries of the world to set aggressive targets for themselves, with policies that make those targets happen. Basically, that's what's happening in the world. The Europeans are acting. The Americans are not, the Australians are not, and other countries, such as Russia and so on, are not taking actions but really are benefiting from reductions that happened earlier.
So only a small part of the world is really acting right now. I think Canada needs to step to the plate and start acting. I think we can help the world more by taking fairly aggressive domestic action right now.
