Tar sands oil is the worst type of oil for the climate, producing three times the greenhouse gas emissions of conventionally produced oil because of the energy required to extract and process tar sands oil. Tar sands consist of heavy crude oil mixed with sand, clay and bitumen. Extraction entails burning natural gas to generate enough heat and steam to melt the oil out of the sand. As many as five barrels of water are needed to produce a single barrel of oil.
TransCanada's proposed $7 billion Keystone XL pipeline would ship heavy crude from Canada's oil sands to refineries on the Texas Gulf Coast. Citizens from across the country have bravely taken action to demonstrate their opposition to the pipeline and make a strong statement that enough is enough. We should not spend even one more dollar to build infrastructure that will continue our dangerous addiction to oil. President Obama must do the right thing now and say no to the Keystone XL pipeline.
