March 4, 2013 Environmentalists Decry State Dept. Environmental Review of Keystone XL ------------------------------------------------------------------------ A State Department review has concluded the proposed Keystone XL tar sands oil pipeline does not pose a serious threat to the environment. The long-awaited assessment acknowledges extraction of tar sands oil produces more greenhouse gases than conventional sources. But it says that increase is only between 5 to 19 percent, not the far greater numbers critics have alleged. The review is seen as a major boost to the pipeline's chances as President Obama nears a decision on its fate. In a statement, the environmentalist group Sierra Club denounced the assessment, saying: "Whether this failure was willful or accidental, this report is nothing short of malpractice. ... [President Obama] should throw the State Department’s report away and reject the dirty and dangerous Keystone XL pipeline." .
