On April 12th 2023, the U.S. EPA published a proposal to further reduce greenhouse gas and criteria pollutant emissions from light- and medium-duty vehicles beyond model year 2027.
Here is a summary of this “multi-pollutant” regulatory proposal.
Vehicles covered in this regulation
The proposal covers light- and medium-duty vehicles, and the graphic below summarizes the vehicle classification. Note that the medium-duty is a new category, which was previously covered by Class 2b and 3 vehicles in the heavy-duty rule. Also note that medium-duty passenger vehicles in the 8,501 – 10,000 lbs. category are excluded from the medium-duty (they fall under light-duty).
