National Journal Energy Experts Blog

Last week, after three years of environmental review, public meetings, and public comment, President Obama postponed until first quarter 2013 a decision on whether or not to approve the Keystone XL Pipeline — the $7 billion, shovel-ready project to deliver up to 830,000 barrels a day of tar sands oil from Canada to U.S. Gulf Coast refineries. Obama’s punt, which Keystone opponents hope effectively kills the pipeline, is topic-of-the-week on National Journal’s Energy Experts Blog. So far, a dozen “experts” have posted, including yours truly.

Now, if you’ve been paying attention at all over the past 40 years, you may suspect that most Keystone opponents want to kill the pipeline just because they hate oil and oil companies — even as they fill up their tanks to drive to the next demonstration. Bill McKibben, lead organizer of the anti-Keystone protest rallies outside the White House, lives in Vermont. On the Colbert Report, host Stephen Colbert asked McKibben: “You’re from Vermont? Did you ride your bicycle down here? Or did you ride ox cart? How did you get down here? Or do you have a vehicle that runs on hypocrisy?”

If we take them at their word, McKibben and his climate guru, NASA scientist James Hansen, oppose Keystone because they believe it will contribute to global warming. How? The cutting-edge method for extracting oil from tar sands is a process called steam assisted gravity drainage. SAGD uses natural gas to heat and liquefy bitumen, a tar-like form of petroleum too viscous to be pumped by conventional wells, and burning natural gas emits carbon dioxide (CO2). So their gripe is that replacing conventional oil with tar sands oil will increase CO2 emissions from the U.S. transport sector. Maybe by only 1% annually,* but to hard-core warmists, any increase is intolerable.

Enter the Law of Unintended Consequences. If McKibben and Hansen succeed in killing the pipeline, petroleum-related CO2 emissions might actually increase! [click to continue…]
