"US EPA Proposes Delaying Enforcement Of Biden Vehicle Pollution Rule"

"Enforcement of rule delayed until 2029 model year. Rule covers six pollutants responsible for smog. EPA says delay will save automakers $1.7 billion. Environmental groups say move will increase illness, deaths."

"WASHINGTON - The U.S. Environmental Protection Agency on Thursday proposed a delay in enforcement of a regulation requiring ‌significant cuts in air pollution from vehicles.


The EPA estimated that delaying former President Joe Biden's anti-pollution rule would save automakers $1.7 billion. Environmental groups criticized the delay, saying it would lead to an increase in preventable illness and premature deaths.

The EPA said the proposal, first ​reported by Reuters earlier Thursday, would delay compliance deadlines for light- and medium-duty vehicles for two years ​until the 2029 model year. It cited the decline in U.S. sales of electric vehicles, which it said ⁠made the more stringent pollution rules unattainable for manufacturers.
In April 2024, Biden's EPA finalized a rule requiring significant ​reductions in so-called "criteria pollutants" emitted from passenger and commercial vehicles from the 2027 through 2032 model years.

The Sierra ​Club criticized the move to delay enforcement of more stringent limits on pollutants from gasoline-powered vehicles. The group said the reductions are "readily achievable using commonsense, low-cost technologies already used by many vehicles."
The Sierra Club added that EPA’s analysis "shows that delaying the ​standards would sharply increase harmful pollution, preventable illness, and premature deaths.""
