Clean Trucks Plan
On August 5, 2021, EPA announced plans to reduce greenhouse gas emissions and other harmful air pollutants from heavy-duty trucks through a series of three rulemakings.
The first rulemaking of this Clean Trucks Plan is a final rule signed on December 20, 2022, which focuses on reducing emissions that form smog and soot and will apply to heavy-duty engines and vehicles beginning in model year 2027.
- Final Rule for Control of Air Pollution from New Motor Vehicles: Heavy-Duty Engine and Vehicle Standards
Two additional rulemakings were recently proposed. One focuses on light- and medium-duty vehicles and addresses multi-pollutant emissions, including greenhouse gas emissions and emissions that form smog and soot, for model year 2027 and later commercial pickup trucks and vans. The other focuses on greenhouse gas emissions for model year 2027 and later heavy-duty vehicles. These additional rulemakings take into consideration recent Congressional action, such as the Inflation Reduction Act of 2022, that the Agency anticipates will lead to greater application of zero-emission vehicle technologies.
