On the intensity target issue, the vocabulary around this issue is highly polluted. People have concepts that are all quite confusing to people. It's important to know that in the Waxman-Markey and Kerry-Boxer bills, for the energy-intensive trade-exposed sectors, the allocation to them is in fact output-based—i.e., intensity. The Canadian system largely applies, apart from electricity, to energy-intensive trade-exposed sectors.
So in fact we're talking about aligning with a system in the U.S. that is intensity for the trade sectors we're covering. And we need to do the allocation in such a way that we don't tilt the balance between Canada and the U.S. for investment and competitiveness.
How will these systems tie together? Well, by doing allocations that are comparable and have a comparable burden on the trade-exposed sectors so that you don't create trade issues between the two countries.
