Why Clean Air Matters

Air pollution affects people where they live, work, learn, and play. In the Houston-Galveston region, pollutants such as fine particulate matter (PM₂.₅), ozone, and toxic air pollutants are linked to asthma attacks, heart disease, missed school days, and other health risks.

Some communities—especially those near major transportation corridors or industrial areas—experience higher exposure and greater health risks.

The Clean Air Action Plan places public health and community well-being at the center of regional air quality planning.
