More than anything else, I have a concern that the toothpaste may be a bit out of the tube. Intensity targets have been discussed not only by this government but previous to that, particularly with Alberta and the large final emitters in the west. If we were to have a very strong political discussion now and insist on absolute caps, it would once again detract from taking action. That's where I'm most concerned.
A lot of this stuff is just polemics and debate: no hard cap, soft cap; Kyoto, not Kyoto. To me it's a matter of starting with some kind of program and getting the act going. Theoretically, having absolute caps is probably the simplest way of implementing something like greenhouse gas emissions trading. But because intensity has been part of the political dialogue for the last few years, my concern is that if we bring that back again it will needlessly politicize the situation, particularly vis-à-vis Alberta.
