I have a quick comment. Policy interactions always go on. Prime Minister Harper's vehicle efficiency regulations and coal-fired power phase-out make it easier for the carbon price to do its job later on, because cars are more efficient and we're using less fuel. Yes, there are more people and we're driving more, but those cars are using less energy and therefore have fewer emissions. Emissions aren't as high, and therefore a carbon price or another policy to hit the target can be lower.
We have all these policies, packages, that are squeezing these emission margins all over the place. We have regulations, subsidies, carbon pricing, and they're all making it easier to hit the target, ultimately.
