We appreciate your interest in Georgia's Clean Air Force - committed to helping the region work toward better air quality
Welcome Motorists and Vehicle Owners
Georgia's Clean Air Force (GCAF) is the state's Vehicle Emissions Inspection and Maintenance (I/M) Program for Atlanta’s 13 metro counties. Since 1996, the program has worked to reduce harmful vehicle emissions and to help improve metro Atlanta’s air quality. Through your participation, there have been significant improvements to Georgia's air quality, including the prevention of tons of ozone-forming pollutants from entering the air we breathe by identifying and repairing more than 4.5 million heavy-polluting vehicles.
For the 2024 registration period, 2000 – 2021 model year gasoline-powered cars and light-duty trucks with an 8,500-pound gross vehicle weight rating (GVWR) or less require an annual emissions test in the following counties: Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, Paulding, and Rockdale. See testing exemptions.
