CLEVELAND, Ohio — Air quality across Northeast Ohio is showing gradual improvement, but several counties — including the region’s most populous — still fail to meet federal standards, according to a new report from the Northeast Ohio Areawide Coordinating Agency.
The report, released this week by NOACA, found that while overall emissions have declined in recent years, many areas continue to exceed U.S. Environmental Protection Agency benchmarks for key pollutants. Cuyahoga County, in particular, remains out of compliance with a majority of federal air quality standards.
NOACA officials say transportation remains the region’s largest contributor to air pollution, accounting for a significant share of emissions tied to ozone and fine particulate matter.
“Although we’re seeing progress, there is still work to be done, especially in urban areas where vehicle traffic is highest,” the agency said in a statement.
The findings highlight ongoing challenges in reducing ground-level ozone, commonly known as smog, and particulate pollution, both of which are linked to respiratory and cardiovascular health risks.
According to the report, emissions reductions have been driven in part by cleaner industrial practices and improvements in vehicle efficiency. However, increased vehicle miles traveled and reliance on personal transportation continue to offset some of those gains.
Cuyahoga County’s continued nonattainment status could have implications for future federal funding and regulatory requirements, including stricter emissions controls and transportation planning mandates.
NOACA officials emphasized the importance of expanding public transit options, promoting electric vehicle adoption, and encouraging alternative modes of transportation such as biking and walking to further reduce emissions.
The agency plans to work with local governments and regional partners to develop strategies aimed at improving air quality and meeting federal standards in the coming years.
