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.

Now that California has taken the lead and set a goal for all passenger vehicles sold in the state to be electric by 2035, the next logical step is electrifying medium- and heavy-duty vehicles. This is an integral step towards cleaning our air and reducing climate-warming emissions. There are more than 1.8 pollution from vehicles.

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. This is the first time EPA has sought to limit emissions in over two decades, and it is long overdue.

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.

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.

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.).

EPA has considered electrification technologies in many past rulemakings and has used fleet average standards for decades.
