Washington DC (September 18, 2019) – Today the Trump Administration announced that it will revoke California’s tailpipe waiver under the Clean Air Act. Tailpipe pollution is the largest source of greenhouse gas emissions in the United States. Revoking the tailpipe waiver would have significant impacts in California and the 13 states that follow the Golden State’s clean air rules. California’s Attorney General has already announced that he will challenge this action in court.

Following is a statement from Dan Lashof, Director, WRI United States:

“President Trump once claimed that he wanted to ‘make states the laboratories of democracy once again.’ His attempt to revoke California’s authority to set vehicle standards to protect people from pollution is like driving a bulldozer through the laboratory.”
