The U.S. Transportation Department is repealing a rule, finalized in the closing days of the Obama administration as part of the fight against global warming, requiring states to track greenhouse gas emissions from vehicles on the nation's highways.
In a notice posted Wednesday in the Federal Register, the Federal Highway Administration, which is part of the Transportation Department, said it was repealing the rule. The repeal becomes effective at the end of June.
A coalition of states in 2017, including California, Massachusetts, Iowa and Washington, had sued to force the Trump administration to continue to enforce the rule, which they agreed to do, pending a formal process to rescind it.
