All but two of the Chicago Transit Authority’s (CTA) 1,800 buses run on diesel fuel. Respiratory Health Association knows the health and environmental effects of vehicle pollution in the air and is focused on finding healthier transportation options for Chicago.
This summer, the Joyce Foundation awarded a one-year grant to help RHA explore the impacts of air pollution in communities throughout the city of Chicago. Funds will support a study of how diesel buses affect the lung health of residents and help increase efforts to educate leaders and the public on the potential benefits of electric vehicles.

RHA’s study will explore the potential health benefits of using electric buses in place of diesel-powered vehicles.
“We see electric buses as a great opportunity, if not a necessity, for a healthier Chicago,” commented Erica Salem, RHA Senior Director, Strategy, Programs & Policy. “The Joyce Foundation’s generous grant allows us to examine how our city can move toward transportation options that provide cleaner air and healthy lungs for all Chicagoans.”
RHA will work closely with the University of Chicago’s Spatial Data Science and the Chicago Department of Public Health to study the health effect diesel buses have across different Chicago neighborhoods. Teams will compare data of those living with lung diseases who also live near busy bus routes, bus garages or maintenance shops to residents living in lower bus traffic communities.
This work builds on RHA’s efforts to secure Mayor Lori Lightfoot’s pledge for cleaner bus options. Chicago lags behind other major US cities like New York, Los Angeles and San Francisco, which have announced plans to move to all electric buses sometime in the next 20 years.
RHA will release a final report in the spring of 2020.
