If the controversial northern leg of the Keystone XL pipeline is approved and built, the resulting amount of carbon emitted into earth’s atmosphere could be up to four times greater than the U.S. State Department estimated, according to a new scientific paper.
First, what’s the Keystone XL? A pipeline (not yet approved) that would “transport raw, toxic tar sands oil right through the American heartland” from Alberta, Canada to refineries in Texas”and threatens to wreak environmental havoc on both sides of the border.” (Natural Resources Defense Council)
So, how and why would the climate impact be four times greater? Here’s the logic: If the new pipeline is built, more tarsands oil will likely be consumed. And the tar sands process ”separating oil from sand and mud”” produces three times the greenhouse gas emissions of conventionally produced oil.
People who support the pipeline claim that with or without the Keystone pipeline, we’ll be consuming the oil and the tar sands will inevitably be developed.
Those in the energy industry are not impressed with arguments by the anti-fracking movement in the state. “They’re skilled at marketing, skilled at hyperbole,”¯ said Rock Zierman, CEO of the California Independent Petroleum Association in Sacramento, a group that represents 550 companies and individuals in the oil industry. “We use less than a total 300 acre-feet of water a year for fracking. That’s equal to what all golf courses in California use in half a day.”
About a third of the 2,000 new oil wells in California are hydraulically fractured, he said. “They talk about air pollution from methane leaks,”¯ Zierman said. “Our air [quality] laws established regional air districts that regulate all our service equipment, every joint, every coupling [that's] permitted.”
