Georgia’s Air Quality Trends

Air Quality Trends, 1990-2017

Overall, air quality is improving in Georgia because emissions of key air pollutants continue to decline from 1990 levels.

CO Emissions

An area chart showing the overall decrease in CO Emissions between the years 1990 and 2017. Most of these emissions come from on-road vehicles.
Carbon Monoxide (CO) levels are down 69% since 1990.

NOx Emissions

An area chart showing the overall decrease in NOx Emissions between the years 1990 and 2017. Most of these emissions come from on-road vehicles and stationary fuel combustion.
Nitrogen Oxide (NOx) levels are down 60% since 1990.

PM2.5 Emissions

Volatile Organic Compounds (VOC) levels are down 54% since 1990.

Economic Growth with Clean Air

Between 1990 and 2017, total emissions of the six key air pollutants dropped by 69 percent in Georgia, while the gross domestic product of Georgia increased by 283 percent.
