With funding from the Bipartisan Infrastructure Law, EPA’s Clean School Bus (CSB) Program provides $5 billion over five years (FY 2022-2026) to replace existing school buses with zero-emission and low-emission models. Under the Program’s first funding opportunity, the 2022 CSB Rebates, EPA solicited applications for zero-emission and low-emission school buses and awarded up to $965 million to fund school bus replacements at nearly 400 schools.
