Resumen de Keystone's climate impact
The controversial Keystone XL oil pipeline will make climate change worse. Carbon dioxide emissions will rise by up to no million tons per year if it goes ahead, a finding that will step up the pressure on US Pres Barack Obama to stop the project. The Canadian energy company TransCanada wants to build Keystone XL to carry oil from the tar sands of Alberta, Canada, to Nebraska. There it would link to existing pipes to refineries on the US Gulf coast.
