I wouldn't say that a carbon tax is the only solution for any country. I think the panellists have said that carbon tax is, at best, part of the solution for Canada, but it's a very important part, putting a price on carbon. In terms of other large countries, China is bringing in place a carbon price starting this year. Australia, which is a very similar country to Canada, had a carbon tax system in place that they removed, but they did it on a national basis, and there is an emissions intensity scheme that they're working on now. It's not true that, simply because a jurisdiction is large, with a large geography, it can't do carbon pricing. I mean, California is as big as Canada in population and also very large geographically, and they have a carbon price. I don't think it stands up that, because we're a large country geographically, carbon pricing isn't a sensible solution for Canada.
