The latest in a string of ambitious climate regulations aims to clean up the heaviest polluters on the road. But truckers are worried.
The regulations would require automakers to produce more electric vehicles and hybrids by gradually tightening limits on tailpipe pollution.
The Biden administration is proposing rules to ensure that two-thirds of new cars and a quarter of new heavy trucks sold in the U.S. by 2032 are all-electric.
The state is expected to write strict auto pollution standards designed to significantly speed the transition to electric vehicles and influence new federal rules.
For the first time since 2001, the government is setting more stringent limits on pollution from trucks, vans, and buses that harms human health.
