Environmentalists ask Clinton to block Keystone

摘要

New York—Environmental groups have asked Secretary of State Hillary Clinton to block permitting for the Keystone XL pipeline, which aims to bring more Canadian oil sands crude to the US. The National Wildlife Federation and 25 other groups said April 23 they had sent a letter to Clinton “calling for suspension of the permitting process for a proposed tar sands pipeline known as Keystone XL,” adding that “the full scope of its environmental and social impacts, including greenhouse gas emissions, have not been considered.”
