Diesel Emission Reduction Project Funding

The Iowa Department of Transportation (Iowa DOT) provides funding for the replacement, retrofit, or conversion of medium- and heavy-duty (MHD) on-road diesel vehicles with new diesel or alternative fuel vehicles. Grants are also available for off-road diesel vehicle replacements and repowers. Grants are available for MHD school buses, transit buses, and trucks. Non-road vehicles and equipment may also be eligible for funding. Eligible applicants include government, nonprofit, and private entities that own or operate diesel fleets and equipment. Additional restrictions apply. This grant program is partially funded by Iowa’s portion of the Volkswagen Environmental Mitigation Trust. For more information, including eligible vehicles, see the IowaDOT Diesel Emission Reduction Act Website.
