Construction of the controversial Keystone XL pipeline was officially terminated on Wednesday, handing a big victory to environmentalists who fought the project for more than a decade as they intensified their battles against other fossil fuel development.

The decision by TC Energy and the government of Alberta to pull the plug on the $8 billion pipeline had been widely expected after Joe Biden scrapped the permit to build its US leg in one of his first acts as president.

“We remain disappointed and frustrated with the circumstances surrounding the Keystone XL project, including the cancellation of the presidential permit for the pipeline’s border crossing,” said Jason Kenney, Alberta premier.
