Ozone Strikes Again: D.C. Receives ‘F’ in 2026 State of the Air

April 22, 2026

Washington, D.C. received a failing grade for ozone pollution in the American Lung Association's 2026 State of the Air report, despite making progress in other air quality categories and achieving federal compliance standards for the first time. The capital's ozone problem stems largely from vehicle emissions and pollution drifting in from neighboring states, with approximately 90% of the city's pollution originating outside its boundaries. The poor air quality disproportionately impacts predominantly Black communities in Wards 7 and 8, where children are 20 times more likely to visit emergency rooms for asthma than those in wealthier Ward 3.

Who is affected

44% of Americans living in areas with failing ozone and particle pollution scores
Washington, D.C. residents, particularly those in Wards 5, 7, and 8
Children and adults with asthma (9.6% of D.C. children and 11.4% of adults)
Children in Wards 7 and 8 (20 times more likely to visit emergency rooms for asthma than Ward 3 children)
People of color nationwide (54.2% of those living in counties with at least one failing grade)
Lower-income residents eligible for the Clean Cars for All program
Almeta Cooper's family, including her seven-month-old grandson

What action is being taken

The Department of Public Works has transitioned approximately 10% of municipal vehicles to electric or plug-in hybrids
The city is working on electrifying its bus system
DOEE has installed PurpleAir and Clarity Node sensors around the city for data collection
A federal air quality monitor and four park bench monitors have been installed in Ward 8
Two switcher trains in Ivy City's railyard are now running on cleaner diesel engines
Joseph Jakuta is preparing to submit a maintenance plan to the EPA on sustaining ozone progress

Why it matters

Ground-level ozone pollution poses serious health risks including respiratory illness, lung cancer, and exacerbated allergies, with communities of color bearing a disproportionate burden. The issue reflects critical environmental justice concerns, as predominantly Black and under-resourced communities face 2.4 times higher likelihood of living in areas with failing grades across all pollution categories. While D.C. has achieved federal compliance for the first time, the fragile progress could be reversed without continued local and federal action. The interconnected nature of regional air quality means D.C.'s efforts alone cannot solve the problem without cooperation from neighboring states, highlighting the complex challenges of addressing metropolitan-area pollution.

What's next

Joseph Jakuta stated the city needs to submit a maintenance plan to the EPA on how ozone progress will be sustained
The District was set to implement California's Clean Cars for All program, but the process has been stalled (timeline unclear)
