The American Lung Association “State of the Air” 2025 is the result of the hard work of many.
We would like to thank: Allen S. Lefohn, Ph.D., of A.S.L. and Associates, who compiled the data; John Balmes, M.D., who served as expert volunteer reviewer for the health impacts section. Special thanks this year goes to the air quality professionals who agreed to share stories about how the work they do makes a difference.
Great appreciation goes to the National Association of Clean Air Agencies, who strove to make this report better through comments, review and concerns. Many of its members reviewed and commented on their state data to verify their accuracy. We also appreciate the assistance of members of the Association of Air Pollution Control Agencies, some of whom also reviewed data from their states. We appreciate them all as our partners in the fight against air pollution. This results in this report should in no way be construed as a comment on the work any of these agencies do.
“State of the Air” 2025 would not have been possible but for the first twenty formative years of inspiration, dedication and hard work of the late Janice E. Nolen. Her spirit still guides us all.
The American Lung Association assumes sole responsibility for the content of “State of the Air” 2025.
