I did look at that. Frankly, I can't draw a causality link. There might have been a correlation in some sectors. I would say, though, that we're tinkering at the margin at $30 a tonne.
Just to give you a sense of proportion, in the work done by the Canadian Academy of Engineering and the David Suzuki Foundation with the McGill researchers, they come in with an implicit carbon tax of $1,200. With the latest fringe technology available, if you were to bring that technology into the market, it would mean that to make that technology financially viable, carbon would have to be taxed at $1,200 a tonne. That's just to give a sense of perspective.
What I would have to give credit to B.C. for is doing something that in fact alleviates some of the pressures on groups that are left behind when you implement such a fiscal tool. It has also been successful in terms of public acceptability, which is a big thing on its own. It's starting to move the needle on the notion that if carbon is something we want to eliminate, we need to price it somehow.
The other thing I'd like to mention, and I think it's really important, is that it's always about the carbon. It's not about the fuel. I'm totally with Simon that the sectors shouldn't be put against each other; every sector should have a fair chance at this.
I would propose that there are some solutions that could be encouraged for oil, gas, and probably even coal. It's not the fuel itself; it's the carbon in it. If we find solutions that get rid of the carbon in it, then we're there. Carbon sequestration is one example, but there could be other solutions we haven't thought through yet.
