Study finds that replacing older, highly polluting school buses could lead to 1.3 million fewer daily absences annually

Green Car Congress

Replacing all of the oldest, highly polluting school buses in the US could lead to 1.3 Even relatively short commutes on school buses can dominate students’ daily air pollution exposures. Applying their results nationwide, the researchers extrapolated that replacing all pre-2000 model school buses would lead to more than 1.3
