Diesel Emission Reduction Act (DERA) National Grants is sponsored by ENVIRONMENTAL PROTECTION AGENCY. The Diesel Emissions Reduction Act, 42 U.S.C. 16132 et seq., as amended, authorizes EPA to award grants, rebates and loans to eligible entities to fund diesel emissions reductions. Emission reductions are achieved through the implementation of a certified engine configuration, verified retrofit technology, or emerging technology for buses (including school buses), medium heavy-duty or heavy heavy-duty diesel trucks, marine engines, locomotives, or nonroad engines used in construction, handling of cargo (including at port or airport), agriculture, mining, or energy production. In addition, eligible entities may also use funds to reduce long-duration idling using verified idle-reduction technology with certain vehicles or equipment described above. The objective of this program is to achieve significant reductions in diesel emissions and exposure, particularly from fleets operating in areas designated by the Administrator as poor air quality areas. Priority is given to projects which promote environmental justice (EJ) by demonstrating benefits to disadvantaged communities. EJ is the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income with respect to the development, implementation and enforcement of environmental laws, regulations and policies.
Funding Priorities - Fiscal Year 2023: The National DERA program works to reduce the pollution emitted from diesel engines across the country through the implementation of various control strategies and involvement of national, state, local and private partners. Priority will be given to projects which achieve significant reductions in diesel emissions and exposure, particularly from fleets operating in poor air quality areas and/or service goods movement facilities. Further, priority for funding may be given to projects which benefit and engage disadvantaged communities, and those which can demonstrate project sustainability, climate change adaptation and workforce development.

On June 11, 2026, U.S. District Judge Richard Gergel ruled that the EPA's February 2025 termination of the $2.8 billion Environmental and Climate Justice Block Grant Program — created by Section 60201 of the Inflation Reduction Act — was arbitrary, capricious, and unlawful. The ruling voids the termination but does not order the EPA to resume the program, leaving the September 30, 2026 statutory deadline as the binding constraint. For the 116 grantees and the coalition of nonprofits, cities, and tribal partners that were already in award negotiations, the next 105 days will determine whether the program survives in any operational form or migrates entirely to the Court of Federal Claims as a damages action.

Applications close June 19, 2026. The geographic scope spans from Pennsylvania to Texas — eighteen states drained by the Mississippi-Atchafalaya system — and the funding model rebuilds the federal conservation playbook around farmer-led demonstrations rather than top-down agency design.
