Houston Business Journal: A new study says the Keystone XL pipeline could produce four times as much global warming pollution as previously believed, the Associated Press reports. The new estimates, from scientists at the Stockholm Environment Institute, were published over the weekend by the journal Nature Climate Change. The earlier estimates by U.S. officials did not take into account that added oil from the pipeline would drop prices by about $3 a barrel and spur consumption that would then create more pollution,...

Climate Effects of Keystone XL Pipeline Significantly Underestimated, Study Finds

Yale Environment 360: The U.S. State Department's final environmental review of the Keystone XL Pipeline may have underestimated carbon dioxide emissions associated with the pipeline by as much as four times, according to a new study published in Nature Climate Change. The addition of Keystone XL crude oil to the market will drive global oil prices down, the authors say, which in turn will increase demand for oil worldwide by as much as 0.6 barrels for every barrel of Keystone XL oil added to the market. The extra oil...

Grist: If the Keystone XL pipeline is built, it could lead to up to four times as much CO2 pollution as the State Department has estimated, according to a new study. And the study wasnt written by activists. It was conducted by scientists at the Stockholm Environment Institute and published in the journal Nature Climate Change. Why are these new figures so much higher than previous ones? The Associated Press explains: The U.S. [State Department's] estimates didnt take into account that the added oil...

Associated Press: The much-debated Keystone XL pipeline could produce four times more global warming pollution than the State Department calculated earlier this year, a new study concludes. The U.S. estimates didn`t take into account that the added oil from the pipeline would drop prices by about $3 a barrel, spurring consumption that would create more pollution, the researchers said. Outside experts not connected to the study gave it mixed reviews. The American Petroleum Institute found the study to be irrelevant...

Keystone climate impact could be four times US State Dept. estimate, study says

CTV: An economic analysis of the proposed Keystone XL pipeline's possible climate impacts has concluded they could be up to four times higher than previously estimated. In the study published in the journal Nature Climate Change, researchers at the Stockholm Environment Institute write that widely quoted U.S. State Department findings that the oilsands pipeline wouldn't make a significant difference missed a major source of greenhouse gas emissions. "It didn't appear that they looked at the market...
