Criteria air contaminants (CACs) means Emissions of criteria air contaminants contribute to smog , poor air quality and acid rain.

CACs include Total Particulate Matter (TPM), Particulate Matter with a diameter less than 10 microns (PM10), Particulate Matter with a diameter less than 2.5 microns (PM2.5), Carbon Monoxide (CO), Nitrogen Oxides (NOx), Sulphur Oxides (SOx), Volatile Organic Compounds (VOC) and Ammonia (NH3).
