EPA Proposes Stronger Standards for Heavy-Duty Vehicles to Promote Clean Air, Protect Communities, and Support Transition to Zero-Emissions Future 3/7/22
The EPA took their first step in the "Clean Trucks Plan", a series of clean air/climate regulations they will develop over the next 3 years to reduce pollution from trucks and buses. EPA proposed standards that called for:
1. Setting stronger nitrogen oxide (NOx) standards for heavy duty trucks beginning in model year (MY) 2027 and tightening the “Phase 2” greenhouse gas (GHG) emissions for MY 2027 and beyond.
2. Setting stronger emissions standards for medium-duty commercial vehicles for MY 2027 and later.
3. Setting “Phase 3” GHG standards for heavy-duty vehicles beginning as soon as MY 2030 that are significantly stronger than the MY 2027 GHG standards
