EPA Proposes Stronger Pollution Limits on New Trucks
March 7, 2022
The U.S. Environmental Protection Agency announced a proposed rulemaking to further restrict emissions of soot-forming nitrogen oxide (NOx) by heavy-duty diesel and gasoline engines starting in model year 2027.
EPA’s intention is to reduce NOx emissions from trucks by as much as 60% in 2045.
The current NOx standard is 0.2 gram per brake horsepower-hour, and was adopted in 2010.
