—in a carbon-constrained future. But the issue is that if B.C. does it alone, it gives an advantage to other jurisdictions that don't have a carbon tax. The question then becomes how to create a level playing field, which B.C. has attempted to do by staying relatively revenue-neutral by reducing corporate taxes at the same time. However, I think many industries would say that although it may have been revenue-neutral overall, it wasn't necessarily so for the industry. But that can be done; you can try to shift the tax base to give more of a price on carbon.
There is an awful lot of R and D going into carbon sequestration, but I don't know if there are specific timelines when we think we'll be able to achieve that. It's part of Canada's challenge--and Paul can add to this—that because we have a fairly small population over a vast area, the economics of renewables can be more challenging.
