Oregon is committed to reducing greenhouse gas emissions and improving air quality. Transportation sources, including medium- and heavy-duty vehicles, are the largest contributor of greenhouse gas emissions in the state. and contributors to the formation of ozone, fine particulate matter and toxic diesel particulate matter. Accelerating the move to zero-emission trucks and buses is an essential step toward helping Oregon achieve its GHG reduction goals of 80% below 1990 levels by 2050.
The
Advanced Clean Trucks Rule requires manufacturers of medium- and heavy-duty vehicles (Class 2b – 8) to sell zero-emission trucks as an increasing percentage of its overall sales from vehicle model year 2025 through 2035.
Frequently Asked Questions: Oregon's Rules for Medium- and Heavy-Duty Vehicles and Engines
Manufacturer Vehicle Sales and Credits – under the ACT Rule, manufacturers may earn, bank and trade ZEV and near zero-emission vehicle credits based on vehicles they produce and deliver for sale in Oregon. While the requirements begin with the 2025 vehicle model year in Oregon, manufacturers could report early ZEV sales starting with the 2022 vehicle model year. Table 1 below shows vehicle model year (2023) reported total numbers of vehicle sales.
Medium- and Heavy-Duty Fleet Report
The Medium- and Heavy-Duty Fleet Report provides information on fleets of five or more medium- and heavy-duty vehicles across the state. This one-time reporting requirement was required under the Advanced Clean Truck Rule. The report will be posted here as it comes available.
Financial incentives and rebates
Vehicles
- Medium- and Heavy-Duty Vehicle Rebate Program (aka Zero-Emissions for Oregon Fleets or ZERO Fleets Rebate Program) – Provides rebates to purchasers of medium- and heavy-duty zero-emission vehicles. Rebate amounts vary depending on the class size of the vehicle. The rebate program will launch in spring 2025.
- Diesel Emission Mitigation Grants Program – Provides grants for scrapping and replacing older diesel engines with cleaner technologies.
Charging infrastructure to support medium and heavy-duty vehicles
- Oregon Zero-Emission Fueling Infrastructure Grant – Provided $15 million in grants supporting medium- and heavy-duty zero-emission vehicle charging and fueling infrastructure. A new round of grant funding will be available in spring 2025.
- Charging and Fueling Infrastructure Grants – Funding from U.S. Department of Transportation to install public electric vehicle charging stations and hydrogen fueling stations for trucks along Interstate 5 and other key freight routes.
- NEVI – Program to install public EV fast-charging stations along major highways and interstates. While primarily focused on EV passenger car charging, there will also be capability for medium-duty vehicle charging.
