States Cleared to Curb Vehicle Pollution

WASHINGTON, D.C. – The Environmental Protection Agency today reaffirmed California’s authority to set tailpipe emissions standards to address its public health and air-quality needs, and other states’ authority to adopt and enforce those standards.  

The EPA reinstated a Clean Air Act waiver that allows states to enforce vehicle tailpipe standards that are stronger than federal standards. 

The following is a statement from Luke Tonachel, director for clean vehicles and fuels at NRDC (Natural Resources Defense Council): 

“States have long been leaders in cleaning up tailpipe pollution, and the EPA is absolutely right to recognize this. State leadership is crucial to move our nation toward cleaner vehicles. 

“While the previous administration tried to undermine this authority, the law clearly gives California and other states the ability to adopt standards to curb the pollution affecting the health of their citizens. Reaffirming this legal authority will protect public health and help address the climate crisis.”
