The EPA is getting ready to finalize a critical regulation limiting emissions of smog-forming nitrogen oxide (NO X ) and soot (or particulate matter, PM 2.5 ) from new heavy-duty trucks. Indefinite delay of more effective emissions technology could permanently impede the path towards cleaning up the diesel truck fleet.

Beginning in 2027, the ACF would require all new medium- and heavy-duty vehicles purchased by public agencies to be emissions-free, including large work trucks and vans, street sweepers, vacuum trucks, and other similar vehicles. There are more than 1.8 pollution from vehicles. Public Agency Fleets.

and nitrogen oxides (NOx) from the numerous commercial and government fleets of MHD vehicles in the state. The ACF is an opportunity to deliver meaningful reductions in air pollution for the most affected communities, but the current proposal falls short of what is technologically and economically feasible.

leader in cleaning up the light duty fleet quietly released its own proposal in August: the Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) has proposed to improve fuel economy of passenger cars and trucks steadily from 2027 through 2032 and heavy-duty pickups and vans from 2030 to 2035.

They will go into effect in model year 2027 and steadily increase in stringency through model year 2032. This is a common sense step that relies on affordable, proven technology already in use in millions of gasoline vehicles outside the US. These new rules apply to all auto manufacturers and only affect new vehicle sales. Far from it.

This year, the Environmental Protection Agency (EPA) and National Highway Traffic Safety Administration (NHTSA) proposed new emissions and fuel economy standards (respectively) for model year 2027-2032 passenger cars and light trucks (sedans, utility vehicles, pickups, etc.).

The transportation sector is also a substantial source of nitrogen oxides and particulates, both of which are dangerous to human health. EPA has considered electrification technologies in many past rulemakings and has used fleet average standards for decades. Transportation is now the source of 28% of U.S.
