A substantial portion of the half-million school buses in the United States are “highly polluting old diesel vehicles,” the researchers write.

Switching to electric school buses could yield significant health and climate benefits, researchers suggest in a new analysis that seeks to quantify those gains in dollar terms.

Published in the journal PNAS, the study estimated the per-mile benefits of replacing diesel buses with electric ones in 3,108 U.S. counties. Researchers combined data about average diesel bus pollution with statistical estimates of the cost of maintenance and repair, the environmental impact of diesel emissions, and the dollar value of new childhood asthma cases and deaths that could be attributed to such pollution.
