For the past ten years, North Carolina has consistently met all federal health-based air quality standards, a milestone that highlights efforts by Mecklenburg County Air Quality, the N.C. Department of Environmental Quality (DEQ), and other partners.
The National Ambient Air Quality Standards are set by the Environmental Protection Agency (EPA) to protect public health, including sensitive groups such as children, older adults, and individuals with asthma. These standards cover six major pollutants: carbon monoxide, lead, nitrogen dioxide, ozone, particle pollution, and sulfur dioxide.
North Carolina has maintained compliance with these standards since August 2015. “Having a local air quality agency in Mecklenburg County that is measuring air pollution, improving air quality and listening and responding to residents has been critical to this achievement,” said Mecklenburg County Air Quality Director Leslie Rhodes. “We are proud to have played a part in achieving a decade of clean air and are committed to working with the community to continue improving air quality.”
Governor Josh Stein commented on the accomplishment: “Achieving ten years of meeting our clean air standards is a testament to what we can accomplish with sound policymaking and strong public and private partnerships. North Carolinians are able to breathe fresh air because of our state’s continued commitment to safeguarding our natural resources.”
In previous decades, both North Carolina and other states faced challenges meeting several of these standards—especially for ozone and particle pollution—which contributed to issues like summer haze in the Blue Ridge Mountains and acid rain affecting forests.
Several actions helped improve air quality over time. These included passing the 2002 Clean Smokestacks Act in North Carolina; advances in federal fuel and engine standards; shifting energy generation away from coal; and reducing emissions from homes, industry, and other sources through regulations as well as voluntary initiatives.
Mecklenburg County launched programs such as Grants to Replace Aging Diesel Engines (GRADE), provided compliance assistance for industry, and ran outreach campaigns encouraging alternatives to single occupancy vehicle use.
“Cars, trucks, and off-road equipment continue to be the largest sources of air pollution here locally and support for initiatives that address these sources is more important than ever,” Rhodes said.
Although overall air quality has improved greatly across North Carolina—including in Mecklenburg County schools where enrollment reached 153,537 students during the 2022-23 school year according to https://www.dpi.nc.gov/—there may still be occasional days when pollution levels affect public health.

Enrollment at Mecklenburg County dropped by 0.4% in the 2022-23 school year compared to the previous year (https://www.dpi.nc.gov/).
