As I've said in my presentation, our advocacy of these science-based targets is based on what we, as Canada, need to do to make our fair share of helping the world avoid two degrees of global warming, which would take us into a realm of economic impacts, impacts on people, and impacts on ecosystems that I think most people would eagerly agree are unacceptable.
As I said in my presentation, on the question of the costs that will be required to meet these targets, that's a serious question, but we have flexibility to design policies that address, for example, sectors that are most exposed to international competitiveness. We have a lot of flexibility in the way we choose to go about this, and I'd remind you all once again that we have other countries that are taking on these targets because they know it's the right thing to do. I would also just remind you that as far as the 2020 target is concerned, the bill does not set in stone that 2020 target. It actually allows the government flexibility to adjust that target, if justified, so there is flexibility there in the 2020 target.
