The 2021 Wisconsin Clean Diesel Grant is now available. To be eligible, application packages must be emailed by 5 p.m. on Jan. 7, 2022. Further instructions and application materials are available in the 'Available Grants' section below.

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 Environmental Mitigation Trust. The Wisconsin Department of Administration is the lead agency for this activity. For details, visit VW Mitigation Program [exit DNR].
