School Buses


School bus emissions harm one of the most vulnerable populations: children. This page provides information on funding opportunities for a variety of school bus replacement projects, including low and zero emission school bus deployment, and information on how your school district can get cleaner school buses. The WCC also funds a variety of School Bus Projects and administers EPA funding programs such as the Diesel Emissions Reduction Act (DERA) and the Bipartisan Infrastructure Law’s (BIL) Clean School Bus programs.


U.S. EPA’s Clean School Bus Program

What is the Bipartisan Infrastructure Law (BIL) Clean School Bus Program?

The Clean School Bus Program offers rebates and grants to eligible entities for the replacement of existing school buses with low-and zero-emission school buses.
