New Study Quadruples Keystone XL Pollution Projections



(8-11-14) A new study concludes that the Keystone XL oil pipeline could produce four times more global warming pollution than the State Department calculated this year.

The proposed pipeline would carry oil from tar sands in western Canada, through Nebraska to Texas. Researchers estimate Keystone XL would increase world carbon by as much as 121 million tons a year--91 million tons more than State Department estimates.

Study lead author, Peter Erickson, says government calculations didn't take into account that oil added from the pipeline would drop prices, which would increase consumption, which in turn would mean more pollution.  

The study is published in the journal, Nature Climate Change.
