EPA proposes new heavy-duty truck emissions rules

Green Car Congress

MARCH 8, 2022

The US Environmental Protection Agency (EPA) is proposing new, stronger standards to promote clean air and reduce pollution from heavy-duty vehicles and engines starting in model year (MY) 2027. This proposed rulemaking builds on and improves the existing emission control program for on-highway heavy-duty engines and vehicles.
