Clean Diesel Grant Programs

The DNR administers the Clean Diesel Grant Programs to help reduce diesel emissions from both public and private vehicle fleets across the state.

These grant programs have made significant achievements across our state. For details, check out the Clean Diesel Grant Summary Report - March 2021.

The DNR does not administer NOx reduction programs related to the Volkswagen (VW) Environmental Mitigation Trust. The Wisconsin Department of Administration is the lead agency for this activity. For details, visit VW Mitigation Program [exit DNR].

We welcome your feedback. Please email your comments or suggestions about the Clean Diesel Grant Programs to DNRCleanDiesel@wisconsin.gov. Thank you!

The U.S. Environmental Protection Agency (EPA) is accepting applications through Jan. 9, 2025 for the 2024 Clean School Bus Rebate Program. The EPA anticipates awarding approximately $965 million in rebates to fund the replacement of existing school buses with clean and zero-emission (ZE) school buses.

Schools may request rebates for up to 50 buses and can use funding for infrastructure, workforce training and other costs. Applications are due on Jan. 9, 2025 by 4 p.m. ET.

Additional information on eligibility, the application process, important dates and funding prioritization is available on EPA’s Clean School Bus Program webpage.
