A Roadmap for Canada's Tar Sands

With the price of oil in the bucket, environentalists have been acting as if Canada's speculative tar sands boom is all but dead. They shouldn't. A report released today by the energy consultancy IHS CERA predicts a nearly 80 percent increase in tar sands production by 2035, and that's assuming strong environmental regulation, weak growth, and low oil prices. Should things work out better for Big Oil, the tar sands will pump out five times the crude they do now and account for a staggering 37 percent of U.S. oil imports.

CERA suggests that this might not be such a bad thing. In an analysis of 11 previous studies, it found that "well-to-wheels" greenhouse gas production from the tar sands is only 5 to 15 percent higher than the average crude oil processed in the United States. Last year, I reported that a team of UC Berkeley researchers had calculated a 30 percent well-to-wheels difference. Either figure is significant when multiplied a potential tar sands output of 6.3 million barrels per day.

Factor in devastation to Canada's boreal forests, streams, and native communities, and the swap of climate security for energy security seems even more faustian. Once we exhaust the tar sands, we'll move on to liquefied coal, which emits 80 percent more greenhouse gasses than regular oil, and then oil shale, which spews twice as much. When will it all end? And more important, what will the weather look like?
