I think I'd echo some of the comments that have come up, which is that every province has very different circumstances, so carbon pricing gives not only a broad policy tool but flexibility in what to do with revenues. It also gives people a lot more flexibility in how they individually react, so you're not, as a government, imposing solutions or believing that you can dictate innovation from on high, or any of these sorts of things; you're relying on the power of the market to generate the outcomes you want.
