Heavy-duty VehicleClean-up Initiative
The Environmental Protection Agency's (EPA) Clean Heavy-Duty Vehicles (CHDV) Grant Program, established under the Inflation Reduction Act, has faced a significant change. As of 2025, all remaining unobligated funds for the program have been rescinded, effectively ending federal financial support for electric or zero-emission heavy-duty vehicle purchases and replacements [3].
This decision halts aid programs for school districts, transit agencies, and trucking firms aimed at electrification. The EPA continues to enforce stricter emissions standards nationally, while certain states have more aggressive zero-emission mandates, but the federal grant funding under this program is no longer available [1].
In addition to the CHDV Grant Program funding cut, recent legislative changes have also withdrawn nearly all federal purchase incentives for electric vehicles, including commercial vehicles, and eliminated credits for charging infrastructure and manufacturing support [3]. This shift marks a policy move away from federal subsidies for electric vehicle adoption.
Despite the funding cut, the EPA has established a new Clean Heavy-Duty Vehicles grant program. This program aims to accelerate the replacement of existing internal combustion engine Class 6 and 7 vehicles with new zero-emission vehicles and associated infrastructure [2]. The 2024 Clean Heavy-Duty Vehicles Grant Program, for instance, proposes to replace an estimated 2,400 school buses and vocational vehicles with new zero-emission vehicles [2].
The purpose of the Clean Heavy-Duty Vehicles grant program is to reduce pollution in neighborhoods where people live, work, play, and go to school [2]. Tentatively, 70 applications have been selected to receive CHDV grant funding [2]. However, the funding opportunity for the Clean Heavy-Duty Vehicles grant program has since closed [2].
Individuals can join the CHDV Listserv for program-related updates, sign up to receive EPA's Clean Heavy-Duty Vehicles e-mail newsletters, or contact cleanhdvehicles@our website for program-related questions [2]. Resources for the Clean Heavy-Duty Vehicles grant program, tentatively selected applications, and project information are available [2]. Grantee Resources are also provided [2].

- The Clean Heavy-Duty Vehicles (CHDV) grant program, initially funded under the Inflation Reduction Act, has been terminated, withdrawing federal subsidies for purchasing or replacing electric or zero-emission heavy-duty vehicles.
- The EPA's policy shift has halted aid programs intended for school districts, transit agencies, and trucking firms, aiming to electrify their vehicles, due to the rescission of all remaining unobligated funds for the CHDV grant program.
- Despite the funding cut, the EPA has introduced a new Clean Heavy-Duty Vehicles grant program, focusing on accelerating the replacement of polluting Class 6 and 7 vehicles with zero-emission alternatives and associated infrastructure.
- The new CHDV grant program is planned to reduce pollution in residential neighborhoods by replacing an estimated 2,400 school buses and vocational vehicles with zero-emission vehicles in 2024, as per the proposed plan.
