On March 28, 2022, Environmental Protection Agency (EPA) published a proposed rule that would set new, more stringent standards to reduce pollution from heavy-duty vehicles and engines starting in model year (MY) 2027. The proposed standards would significantly 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.
Zevin Asset Management presented the following testimony in a virtual public hearing at EPA for the proposed rule.
