Tar Sands and the Carbon Numbers

This page opposes the building of a 1,700-mile pipeline called the Keystone XL, which would carry diluted bitumen — an acidic crude oil — from Canada’s Alberta tar sands to the Texas Gulf Coast. We have two main concerns: the risk of oil spills along the pipeline, which would traverse highly sensitive terrain, and the fact that the extraction of petroleum from the tar sands creates far more greenhouse emissions than conventional production does.
