You would think that, given the disaster in The Gulf, it would be clear sailing for the Keystone XL pipeline, that would import up to 900,000 barrels per day of tar sands oil from Alberta, Canada to the U.S. Gulf Coast. You would, however, be wrong, as this letter from 50 congressional representatives makes clear:
Please join us in asking Secretary Clinton to consider the climate change impacts when determining whether it is in our national interest to increase the amount of tar sands oil imported into the United States.
All but two signatories (Price and Moran) are Democrats, for what that's worth.
And an interesting justification:
As members of Congress, we are bound to protect the national interest of this country and its citizens. Building this pipeline has the potential to undermine America’s clean energy future and international leadership on climate change; we ask that the Department of State exercise due diligence in its permitting process for Keystone XL, carefully weighing all impacts of the project.
As I've argued before, if Canada cannot force an oil sands clean-up, then let the yanks do it for us, even if their environmental concern is a mere guise for protectionism. After all, the Americans are immune to Western rumblings about building fire-walls and separating.
