Air Quality

Welcome to our site, dedicated to clean air in Travis County. We are part of the Natural Resources and Environment Quality division of TNR (Transportation and Natural Resources.) Keep checking in as we build our site with news, links and other resources to help you access information and programs in support of Clean Travis County Air!

The air in Travis County may look clear and clean, but Travis County is known as a near-nonattainment for ozone. That means Travis County is close to being designated a dirty city like Dallas and Houston. Travis County is committed to participating in air quality initiatives with other regional partners to improve our air quality. The regional effort is coordinated through the Capital Area Council of Governments’ Air Central Texas initiative.

Ground-level ozone is the area’s number one air quality issue. Close second is particulate matter for our area. Poor air quality has a negative impact on a person’s health and our ecosystem.

What is ozone and what are the health impacts?

What is Travis County doing?

Travis County is a member of Clean Air Coalition, a voluntary association of organizations that support the regional effort toward improvement of air quality in the Austin-Round Rock Metropolitan Statistical Area (MSA).

The purpose of the CAC is to:

  • Develop, adopt, and implement clean-air plans to achieve and maintain compliance with federal ground-level ozone standards
  • Establish and monitor a regional effort toward the improvement of air quality
  • Develop policies and strategies that will provide guidance for each of its independent governing bodies about actions that will achieve clean air in Central Texas
  • Work cooperatively to achieve clean air standards that will protect public health while allowing organizations to select measures best suited to each community's and organization's needs and resources

In December 2018, the Clean Air Coalition and other stakeholders developed and implemented the 2019-2023 Regional Air Quality Plan designed to help keep Central Texas’ air clean. The regional plan serves as a guide to maintain and improve outdoor air quality; reduce the impact of emissions; and mitigate health, environmental, economic and social impacts of regional air pollution.

In addition to working with local governments and business to develop strategies to reduce air pollution, Travis County has been recognized as one of the Best Workplaces for Commuters in the nation since 2019. Travis County is 1 of 5 organizations in Texas with this designation. To be nationally designated as one of the Best Workplaces for Commuters, Travis County has met the National Standard of Excellence in offering our employees exceptional commuter benefits.
