Mission and Goal

Texas is a state with more than 20 million licensed vehicles and a population that loves to drive. Our love affair with automobiles has meant that, in some areas of the state, emissions from cars and trucks make up half of all the air pollution.

The Texas Department of Transportation and Texas Commission on Environmental Quality launched the statewide Drive Clean Across Texas initiative in 2001, with the goal of raising awareness about the impact of vehicle emissions on air quality and motivating drivers to take steps to reduce air pollution.

The campaign's activities are concentrated during the hot summer months when ozone levels spike and in areas of the state that fail to meet, or come close to failing, federal air quality standards: Houston, Dallas/Fort Worth, El Paso, Beaumont/Port Arthur, Austin, San Antonio, Corpus Christi, Tyler, and Victoria.

Drive Clean Across Texas is making a difference. Air quality messages are now regularly reaching millions of Texas drivers each year in locations and times where and when pollution levels are highest. Awareness of the health risks of air pollution has increased, and drivers now recognize that even small steps can reduce harmful tailpipe emissions.

Nonattainment and Near-nonattainment areas in Texas

Three metro areas of Texas are considered to be in "nonattainment" under the Clean Air Act, meaning they do not meet federal air quality standards because pollutant levels are too high: Houston/Galveston, Dallas/Fort Worth, and El Paso. Several more are considered in “near-nonattainment” or “attainment-maintenance” because they are close to exceeding federal air quality standards: Austin, San Antonio, Victoria, Tyler/Longview, Beaumont/Port Arthur, and Corpus Christi.
