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.
In Spring 2023, EPA opened a competitive grant funding program; EPA anticipates awarding at least $400 million under the 2023 CSB Grants Program Notice of Funding Opportunity (NOFO). EPA expects to announce the 2023 Grant Program selectees by early 2024. In Fall 2023, EPA opened the 2023 CSB Rebates program; EPA expects to award at least $500 million in funding under the 2023 rebate program.
