2022年12月20日，美国环保署EPA（U.S.Environmental Protection Agency）通过了一项最终规则，即《控制新型机动车的空气污染：重型发动机和车辆标准》-“ControlofAirPollutionfromNewMotorVehicles: Heavy-DutyEngineandVehicleStandards,”，该规则制定了更严格的排放标准，以进一步减少空气污染，包括从2027车型年起重型道路车...
On March 29, 2024, EPA announced new emission standards for heavy-duty vehicles for model years 2027 through 2032. The rule,Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles – Phase 3, regulates heavy-duty vocational vehicles such as delivery trucks, refuse haulers, and public uti...
depending on the type of vehicle and use, the agency said. For instance, 30% of "heavy-heavy-duty vocational" trucks would need to be zero-emission by 2032, the EPA said, while 40% of short-haul "day cabs" would need be zero emission vehicles. ...
The Environmental Protection Agency has set strict emissions standards for heavy-duty trucks, buses and other large vehicles.
The rulemaking also proposes additional revisions and clarification to certain highway heavy-duty vehicle provisions and certain test procedures for heavy-duty engines. EPA Proposes Stricter Greenhouse Gas Standards for Heavy-Duty Trucks Faster Adoption of Zero-Emission Vehicles The agency explained t...

The light-duty, heavy-duty, and PEF proposed rules, once finalized, should work together to reduce emissions from the transportation sector. Along with the CAFE standards to be proposed and finalized by NHTSA, compliance plans for vehicle manufacturers for future model years are likely to be sign...
These testing data further show that NOx emissions from heavy-duty diesel vehicles are high during many periods of vehicle operation that are not subject to current on-the-road emission standards. For example, “low-load” engine conditions occur when a vehicle operates in stop-and-go traffic ...
s broader Clean Trucks Plan. He stressed that this NOx rule was made as strong as possible, done as soon as possible and crafted for a time period as long as possible. The final rule is called “Control of Air Pollution from New Motor Vehicles: Heavy-Duty Engine and Vehicle Standards.”...
The 2024 Clean Heavy-Duty Vehicles Grant Program will support the adoption and deployment of eligible Class 6 and 7 zero-emission vehicles while also funding zero-emission vehicle fueling infrastructure and workforce development and training. Across the nation, over 3 mil...
