Keystone XL and Climate Change: Much Ado About 0.00001°C/yr. (May 7th Testimony before Congress)

By Chip Knappenberger -- May 8, 2013

“No matter whose carbon dioxide emissions estimate is used, the climate impact of the oil transported by the pipeline is too small to measure or carry any physical significance. In deciding the fate of the Keystone XL pipeline, it is important not to let symbolism cloud these facts.” [1]

Climate change results from a variety of factors, both human and natural. The primary concern raised over the pipeline involves the carbon dioxide emissions that will result from the production and use of the oil that the pipeline will carry. It is the potential climate change from these emissions that will be the focus of my testimony.

In its Draft Environmental Impact Statement, the State Department finds, and I think that there is broad agreement on this point, that a barrel of oil produced from the Canadian tar sands carries about a 17 percent carbon dioxide emissions premium compared to the average barrel of oil finding its way into the U.S.
