Report from The Sierra Club & Oil Change International: FAIL: HOW THE KEYSTONE XL TAR SANDS PIPELINE FLUNKS THE CLIMATE TEST

Tar sands (or bitumen) has a very high carbon content compared to other sources of oil. Extracting and upgrading oil from tar sands can be as much as 4.5 times more greenhouse-gas-intensive than oil from other conventional North American crude sources. Additionally, during the refining process, 15-30 percent of each barrel of tar sands bitumen becomes a highly polluting byproduct called petroleum coke. The ultimate result is that tar sands bitumen results in significantly more greenhouse gas emissions than conventional oil.
