I have two comments on that. First of all, there are going to be a lot of impediments to the development of a carbon market in Canada. Canada is way too small to be a carbon market itself, so until we can develop links to the rest of the world, it won't work. A number of other impediments are going to be there.
But let's also be sure we don't have the tail wagging the dog. The objective is not to have a carbon market. The objective is to reduce the greenhouse gas intensity and ultimately the greenhouse gases in the economy.
The carbon market can be facilitative. The issue is, let's get the signals in place that make people's investment decisions move in the right direction. Over time, a carbon market will likely emerge.
