Optional Reduced NOx Emission Standards for Heavy-duty Engines
This page last reviewed March 8, 2013
California Air Resources Board (ARB) staff is now seeking input on developing optional low oxides of nitrogen (NOx) emission standards for on-road heavy-duty engines. ARB staff would like to encourage engine manufacturers to introduce new technologies to reduce NOx emissions below the current mandatory on-road heavy-duty diesel engine emission standards for model years 2010 and later. California’s current emission standards for heavy-duty engines are contained in California Code of Regulations, Title 13, section 1956.8. It is envisioned that the proposed optional low NOx standards would encourage engine manufacturers to showcase new technologies and could be utilized to prioritize funding in incentive programs such as the Carl Moyer Memorial Air Quality Standards Attainment Program. Staff plans to propose new optional low NOx standards for on-road heavy-duty engines to the Board in late 2013.
