CSSN Director of Research Robert Brulle speaks with Bloomberg Law on the climate movement’s efforts to block the Keystone XL pipeline.

“The protest over the Keystone pipeline was a massive development in the climate movement,” and the project’s cancellation “is a testament to the effectiveness of collective citizen action,” said Robert Brulle, a visiting professor at Brown University who is an expert on environmental activism.

Opposition to Keystone, he added, amplified action against climate change and “marked the end of the unprotested expansion of oil and gas infrastructure in the U.S.”
