WASHINGTON (January 12, 2021) — Today, the U.S. Environmental Protection Agency (EPA) recognizes seven groups and individuals for their innovative work on clean air projects. The 2020 Clean Air Excellence Awards were given to state, local, tribal, and private sector programs that educate the public in improving air quality or reducing harmful air pollutants that threaten health and the environment.

“For 17 years, the Clean Air Excellence awards have honored those who go above and beyond to improve air quality both at the local and national level,” said Anne Austin, Principal Deputy Assistant Administrator for EPA's Office of Air and Radiation. “Our winners’ inspirational dedication to environmental protection is a model for all of us, and we look forward to many more years of clean air innovation and collaboration.”
