EPN Presents Testimony on EPA’s Proposed Pollution Standards for Heavy-Duty Vehicles

On April 12, 2022, EPN presented testimony at a virtual public hearing on EPA’s proposal to set new, more stringent standards to reduce pollution from heavy-duty vehicles and engines starting in model year (MY) 2027. The proposed standards would reduce emissions of smog- and soot-forming nitrogen oxides (NOx) from heavy-duty gasoline and diesel engines and set more stringent greenhouse gas (GHG) standards for certain commercial vehicle categories. EPN strongly recommended that EPA strengthen both the NOx and GHG requirements in the Final Rule to maintain the agency’s leadership in improving air quality and public health and addressing the global climate crisis.

Read EPN’s testimony presented by Mike Walsh, former Director, Motor Vehicle Pollution Control Program.

EPN member Gary Timm, former Chief, Chemical Testing Branch, EPA Office of Pollution Prevention and Toxics, also provided written testimony in his own capacity on EPA’s proposal.
