    School Bus Rebates

NEW: For more information on funding opportunities for clean and zero-emission school buses, learn about the Bipartisan Infrastructure Law Clean School Bus Program.


The Diesel Emissions Reduction Act (DERA) of 2010 (pdf) (133 KB , January 2011) allows EPA to offer rebates in addition to grants to reduce harmful emissions from older, dirtier diesel vehicles. The rebate program has funded vehicle replacements or retrofits for over 2,000 vehicles. Typically, the rebate application period opens in the fall and projects are completed in less than one year.

For 2021, in addition to the annual DERA School Bus Rebates detailed below, EPA is offering separate rebates for electric school bus replacements in underserved communities funded by the 2021 American Rescue Plan (ARP).

For more details on the 2021 ARP Electric School Bus Rebates, including a table comparing the two programs.

2021 DERA School Bus Rebates CLOSED

School buses travel over four billion miles each year, providing the safest transportation to and from school for more than 25 million American children every day. However, diesel exhaust from these buses has a negative impact on human health, especially for children, who have a faster breathing rate than adults and whose lungs are not yet fully developed.

The 2021 DERA School Bus Rebates will offer approximately $10 million to public and private fleet owners for the replacement of old diesel school buses with new buses certified to EPA’s cleanest emission standards. Selected applicants that scrap and replace their old diesel buses will receive a rebate of $20,000-$65,000 per bus depending on the fuel type of the replacement bus.
