At the top of the long list of serious problems with the State Department’s Draft Supplemental Environmental Impact Statement (SEIS) for the Keystone XL tar sands pipeline is the assertion that the pipeline will have no impact on climate change. The State Department asserts that if the pipeline is not built, the tar sands in Alberta will be exploited one way or another. Therefore, State asserts, the emissions in question will be released regardless of the Keystone XL pipeline. This is simply incorrect.
