First of all, I'd like to add that Canada's carbon pricing system is also a good thing because the money goes back into Canadians' pockets. That's another very interesting point.
With respect to the United States, most of their commitments are massive and very significant. It's really great that they have finally taken this step, but they don't have many regulatory measures. These are mostly investments in incentives. They're using the carrot much more than the stick. Once again, it's far more efficient to send a price signal on emissions, like we're doing with carbon pricing.
