As fossil fuel interests attack climate accountability litigation, environmental advocates have sounded a new warning that they are pursuing a path that would destroy all future prospects for such cases.

Nearly 200 advocacy groups have urged Democratic representatives to “proactively and affirmatively” reject potential industry attempts to obtain immunity from litigation.

“We have reason to believe that the fossil fuel industry and its allies will use the chaos and overreach of the new Trump administration to attempt yet again to…shield themselves from facing consequences for their decades of pollution and deception,” reads a letter to Congress on Wednesday. It was signed by 195 environmental groups such as the Sierra Club, Earthjustice, and Sunrise Movement; legal nonprofits including the American Association for Justice and Public Justice; and dozens of other organizations.
