Electric school buses offer cleaner air for students, reduced operating costs for districts, and long-term climate and workforce benefits. Yet most U.S. school buses still run on diesel. Achieving full electrification will require coordinated action across utilities, manufacturers, school districts, technical advisors, financing institutions, and federal, state, and local officials. The newly released Roadmap to 100: Electrifying the Full US School Bus Fleet, developed by the World Resources Institute (WRI) and the Center for Transportation and the Environment outlines the barriers slowing adoption and the solutions that can unlock progress at scale.
