TransCanada says Keystone XL will not exacerbate global warming

NEW YORK — TransCanada Corp.’s proposed Keystone XL pipeline will not significantly exacerbate the United States’ greenhouse gas (GHG) emissions, the Calgary, Alberta-based pipeline company wrote in a letter to the State Department.

President Obama said in a recent speech on climate change that Keystone XL’s approval would depend largely on its expected impact on GHG emissions (amm.com, June 26) GHG emissions from products carried by Keystone XL are expected to total 18.7 million tonnes, which would lead to a global temperature increase of "less than one one-hundred thousandth of a degree," according to the letter.

Meanwhile, the pipeline itself will have few emissions as it is powered by electric motors, TransCanada said.

Oil transported via the pipeline from the Alberta oil sands to the Gulf Coast is not significantly different in terms of life-cycle GHG emissions than other heavy crudes it would displace, for example from Venezuala and Mexico, according to the letter.
