Things to know about the Trump administration order on car and pickup fuel economy - The Associated Press

The Trump administration, through its latest executive order, is putting power back into the hands of American consumers and auto manufacturers, rolling back restrictive fuel economy regulations. Supporters argue this move will reduce vehicle costs and support the domestic auto industry, asserting that the market, not the government, should drive fuel efficiency improvements.

In a move that undermines years of progress in the battle against climate change, the newly appointed transportation secretary has swiftly moved to weaken fuel economy standards for cars and pickups. Environmentalists argue this rollback serves the interests of oil companies over the planet's future and public health, signaling a significant threat to U.S. commitments to reducing greenhouse gas emissions.
