25 million American children ride school buses to and from school every day, and the exhaust from school bus tailpipes has an impact on their developing lungs.

A recent study by researchers at the University of Washington and the University of Michigan shows that reducing bus emissions, by using cleaner fuels and retrofitting buses with special emissions-reducing devices, has a measurable impact both on students’ lungs, and on their attendance records.

Students with and without asthma benefitted from cleaner buses – those riding in buses emitting less pollution saw significant reductions in a marker for lung inflammation.

Researchers noted an effect on absences as well, finding that “there was an 8 percent lower risk of being absent in the previous month when riding a bus with ultra low sulfur diesel fuel. For those riding a bus that was fitted with a diesel oxidation catalyst, there was a 6 percent reduction in the risk of absenteeism.” On a national scale, retrofitting buses and choosing cleaner-burning fuels could mean a 14 million day reduction in absenteeism.
