It is in principle, Mr. Chair, conceivable to do that, because the point of trading, as Mr. McGuinty will know, is to calculate the emission reductions to which a credit or an allowance is applied. To the extent that an intensity-based system requires a different approach to calculating that, one would have to do a crosswalk between a system that is based on hard caps and one that's based on intensity. But assuming that both systems actually do result in reduced emissions that can be converted, then it would be, in principle, possible to have the two coexist. I'm not saying they will; I'm saying it is possible.
