June 4, 2018—The Environmental Protection Agency (EPA) submitted on Thursday its proposal to roll back climate change rules that required automakers to nearly double the fuel economy of passenger vehicles, reported the New York Times.
One of the elements of the proposed rule would formally challenge California's status under the 1970 Clean Air Act to set its own vehicle pollution standards, according to the report. California said it will continue to enforce the stricter, Obama-era pollution standards.
12 other states follow in California's lead, making up roughly one-third of the nation's auto market.
The EPA's proposal would require automakers to double the fuel economy of passenger vehicles to an average of more than 50 miles per gallon by 2025.
The Obama-era rule was designed to cut pollution from vehicle tailpipes, according to the New York Times.
