Electric school bus carbon test: Why the EPA’s new green-school grants matter
SalonThere are currently more than half a million diesel school buses rumbling and coughing along America's roadways in 2024, carrying around 24 million students to public and private schools alike. On Monday, a trio of Harvard health and environmental scientists found that school districts would save an average of $247,600 in costs for every one of the roughly 200,000 high-emission heavy duty vehicles they replace with an electric bus. Chan School of Public Health found that lowering the number of emissions-driven deaths and childhood asthma cases — not to mention reducing negative climate impacts — by replacing old diesel buses with new electric ones via EPA funding would save about "$207,200 per bus and $40,400 per bus, respectively." The study's authors found that if the entire fleet of U.S. school buses had been replaced in 2017 with EVs, emissions-related deaths would have been reduced by around 24 times, and new childhood asthma cases would have been reduced by around 23-fold.
