The Trump administration rolled back Obama-era pollution and fuel efficiency rules for cars and light trucks on Monday, saying they were too stringent.

The decision by President Donald Trump's Environmental Protection Agency means the emission standards for vehicles in the 2022-2025 model years will be revised, as sought by automakers.

"The Obama administration's determination was wrong," said EPA chief Scott Pruitt.

Former President Barack Obama's EPA "made assumptions about the standards that didn't comport with reality, and set the standards too high," Pruitt said in a statement.

The Alliance of Automobile Manufacturers applauded the move, saying it would "keep new vehicles affordable to more Americans." "This was the right decision, and we support the administration for pursuing a data-driven effort and a single national program as it works to finalize future standards," said the industry group representing Fiat Chrysler, Ford, General Motors, Toyota, Volkswagen and others.

The rules set in 2012, known as the Corporate Average Fuel Economy or CAFE standards, sought to reduce pollutants released into the air by gradually increasing fuel efficiency across all models offered by manufacturers to 54.5 miles per gallon (4.32 liters per 100 kilometers), compared to 35.5 miles per gallon in 2016.
