The Obama administration rejected the Keystone XL oil pipeline on Friday, handing a major victory to environmentalists after a seven-year review process that gave rise to a grassroots climate activist movement. President Barack Obama announced his decision at a morning news conference in the White House Roosevelt Room, alongside Secretary of State John Kerry and Vice President Joe Biden.

“The State Department has decided the Keystone XL pipeline would not serve the national interests of the United States,” Obama said. “I agree with that decision.”

The rejection comes only weeks ahead of a crucial climate summit in Paris, where diplomats will work to forge a new global warming agreement to limit greenhouse gas emissions for all countries starting in 2020. The administration has committed to reducing U.S. carbon emissions by 26% to 28% below 2005 levels by 2025, and is pushing for an ambitious climate agreement to be forged.
