Across the country, fall is synonymous with the new school year: sharpened pencils, new bento-style lunch boxes and, for many, the return of the iconic yellow school bus. Only this year, millions of students will be transported by yellow school buses that are electric.
This change was several years in the making, and it’s a welcome one: Diesel buses — which comprise the majority of school buses in use today — spew exhaust that has been linked to serious physical and cognitive issues in children.
“Diesel school buses are incredibly polluting, not just for the environment — for air quality — but for children’s health. They are very harmful to children’s respiratory health, lung health, you name it,” says Carolina Chacon, the coalition manager for the Alliance for Electric School Buses. Studies have shown that diesel fumes, one of the most toxic forms of air pollution, are associated with heart and lung conditions such as asthma as well as cognitive performance issues. Even students who ride buses that have been retrofitted with cheap engine modifications like “diesel particulate filters” perform better on tests, according to researchers at Georgia State University. “The science behind it is really clear that diesel is harmful, period. But for kids, whose lungs and brains are still developing, it is especially bad,” Chacon says.
When the Alliance for Electric School Buses formed in 2018, members were focused on demanding governors use the Volkswagen settlement funds [from the Volkswagen emissions scandal, aka Dieselgate] to purchase electric school buses. But in most states, the governors or their environmental departments chose to use the funds to swap out older diesel buses for “clean diesel” buses. This was a move in the right direction, but a lower bar than what the Alliance for Electric School Buses was fighting for.
Then, in 2019, the Alliance switched its focus to policy. It began working with the office of then-Senator Kamala Harris to introduce the first electric school bus bill to Congress. “Her office actually drafted the Clean School Bus Act of 2019,” Chacon says. The bill didn’t advance far, though, and Harris ended up running for president in 2020. “But the need for electric school buses did become a talking point during the primary,” Chacon says. “It was something Harris brought to the table, and that [Washington] Governor Jay Inslee brought to the table.”
