News release: “The proposed Keystone XL tar sands pipeline would significantly boost the carbon pollution that drives climate change, failing the test set by President Obama, according to a detailed analysis by the Natural Resources Defense Council. In just one key way, over its 50-year life, the Keystone XL tar sands pipeline would add up to 1.2 billion metric tons more carbon pollution than if it carried conventional crude. That is more than every car in the United States releases into the air in an entire year. Furthermore, the overall increase in carbon pollution triggered by Keystone XL would be similar to the emission reductions from one of the most ambitious initiatives now underway: new U.S. heavy truck emission and efficiency rules.”
