Emissions from industrial facilities and electric utilities, motor vehicle exhaust, gasoline vapors, and chemical solvents are some of the major sources of oxides of nitrogen (NOx) and volatile organic compounds (VOC).

About Air Quality

San Antonio is home to a pleasant, warm climate, booming economy and growing population. In fact, San Antonio stands to welcome one million more residents by the year 2040. With these new residents come challenges for transportation, providing services and keeping the air we breathe clean.

San Antonio’s air doesn’t look dirty, but the truth is we have surpassed the U.S. Environmental Protection Agency’s (EPA) health-based clean air standards. We must work together to reduce pollution and clean up our air. Clean air benefits the entire community.

Specifically, Bexar County is in exceedance of ground-level ozone standards. Ground-level ozone forms when Nitrogen Oxides (such as from burning fossil fuels in combustion engines) combine with Volatile Organic Compounds in the air and sunlight to make ozone.


Put simply, air pollution damages lung tissue in ways similar to second hand tobacco smoke. Air pollution triggers heart attacks and strokes. It causes diseases like bronchitis and lung cancer. It sends people to the emergency room with respiratory problems such as asthma attacks.

Beyond impacting your health, poor air quality is bad for our economy. A stricter federal air quality standard means additional regulations for businesses that want to expand or relocate to San Antonio, putting new jobs and investment in the area at risk. Join us as we work together to clean up our air quality.
