Exhaust emissions of CO2, CH4, and N2O, described collectively as “greenhouse gas pollutants” (GHG), are regulated primarily based on their impact on the climate. Vehicle chassis manufacturers are directly required to certify their vehicles annually against the standards in §1037.104 through §1037.106 (based on vehicle category and weight class). In some cases, engine manufacturers may also have GHG certification obligations defined in 40 CFR Part 1036 (for example the CH4 and N2O emissions for vocational vehicles are excluded from Part 1037).Get Certified
