Even if there were CO2 limits imposed on the industry and you had to look at something like sequestration, with the expansion in the industry, the changing environmental standards you'd be required to accommodate would be substantial. The expansion of the industry seems to be the major problem to the region, not the long-term viability of the industry. Certainly I think we can safely say that it's going to be around for a while.
In 1990, when you were taking out 300,000 barrels a day, you had a 500-year supply. At 3.5 million barrels a day, you're down to a 170-year supply. That works out to about a billion barrels a year at 3.5 million barrels a day. And that's only by 2015. What are we looking at in the future as we continue to ramp up?
The long-term viability of the oil sands industry is strictly dependent on how many barrels per day you produce. At some point in time, somebody has to ask the question, how much should we produce? What is the reasonable limit for a resource like the tar sands? I don't know if that work has been done, but certainly I think this committee has to aim at understanding that.
