A Canadian market is probably a good first step, but we need to think of a broader market. Considered with the U.S., Canada's emissions are roughly 2% of the world's, give or take a fraction. This is a relatively small part of the action in greenhouse gas emissions reductions. To find where those cheap emissions possibilities are, you want a bigger market. That's why in other places I've advocated a North American approach, in part to deal with those issues.
