The reason I ask is that when we're looking at questions of, say, the development of the tar sands in northern Alberta, the proposal to use your industry to transport natural gas to that development to then produce tar sand oil is, in a climate change analysis, a rather terrible equation in terms of the amount of greenhouse gas emitted throughout that process. It is using one of the cleaner products we have to produce what would be called one of the dirtier products. The full equation of that on a climate change front is rather disastrous.
Is it not, as suggested by former Premier Lougheed and even by Mr. Klein, up to government to play some sort of facilitating and cost accounting role? When you folks build the transmission and others produce the natural gas and others use the natural gas in that way, no one is picking up the tab for the emissions that are coming out. I didn't hear in your presentation any notion of a cap-and-trade system or any of those types of solutions that have been suggested. Does that not need to be developed in order to truly capture the cost of something like the tar sands project and bring it under some control?
