Chicago’s communities of color are consistently impacted by air pollution at higher rates, contributing to racial disparities in health risks. A 2025 zoning and land use assessment from Chicago’s Metropolitan Planning Council found that Chicagoans of Latin descent face elevated air pollution; an estimated 50 percent of the population living in areas with the most air pollution from fine particulate matter are Latino, compared to only 30 percent of the city’s overall population. The agreement outlined steps for the city to take to address environmental inequities, including enhanced monitoring of neighborhood-level air pollution. To meet the agreement requirements, the city is installing 277 Clarity air sensors around the city. “It is a series of choices, and those choices could be different.”Though the Clarity system is still incomplete, it’s already sparking change.
