The U.S. Environmental Protection Agency is overhauling its $5bn Clean School Bus Program after its inspector general found weak oversight, fraud risks, and poor monitoring of applicant information, spending, and bus deployment. The agency says it has completed or is addressing 11 recommendations, including stricter verification, controlled fund accounts, better eligibility documentation, and stronger financial guidance. With $2.37bn still available, the relaunch will also invite input on biofuels, natural gas, and hydrogen, marking a broader approach beyond the earlier focus on electric buses.
