I confess that I haven't memorized all the other aspects of it. I consider the 2020 target to be a fundamental flaw, actually, in the whole approach.
If you talk about putting an emission pricing system in place as opposed to a particular form of it, we've been working on that, as I say, for seven years, and the government still has its work-in-progress on the details. I think we can get going along that path.
As I said, I think putting a target in place that would require a 50% reduction in the GHG intensity of GDP in this country by 2020 would be an enormous diversion of attention. We'd use all our time arguing about the target and who's going to pick up the costs and all of this, and we wouldn't even be able to get going. We'd still be here years from now arguing about it.
