"In light of recent data, the current standards are not appropriate and should be revised," according to an EPA press release.
"The Obama administration's determination was wrong," Mr. Pruitt said in the press release. "Obama's EPA cut the Midterm Evaluation process short with politically charged expediency, made assumptions about the standards that didn't comport with reality, and set the standards too high."
Mr. Pruitt also said the agency was re-examining a Clean Air Act waiver granted to California to impose stricter standards than federal law for vehicle emissions of certain pollutants.
"Cooperative federalism doesn't mean that one state can dictate standards for the rest of the country," he said. "EPA will set a national standard for greenhouse gas emissions that allows auto manufacturers to make cars that people both want and can afford, while still expanding environmental and safety benefits of newer cars."
In response to the EPA announcement, the Motor & Equipment Manufacturers Association (MEMA) said that while it supports adjustments to the 2022-25 CAFE standards, it does not support significant changes to the standards.
MEMA pledged to keep working with the EPA, the State of California and the National Highway Traffic Safety Administration on standards that strike a balance between consumer choice, affordability and technological development.
