I remind Mr. Cullen, through you, Mr. Chair, that this clause deals with regulating emission limits; performance standards; market-based mechanisms; emissions trading; offsets; spending; fiscal incentives; a just transition fund; cooperation agreements with provinces, territories, and other governments; and the Canadian greenhouse gas emission reductions that are reasonably expected to result from each of those measures. The area of the baseline that he talks about is only one aspect of the clause, but it's a pretty broad clause, Mr. Chair.
