The Central Texas Clean Air Coalition

The Central Texas Clean Air Coalition (CAC) is a voluntary association of organizations that support the regional effort toward improvement of air quality in the Austin-Round Rock Metropolitan Statistical Area (MSA), which consists of Bastrop, Caldwell, Hays, Travis, and Williamson Counties. 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

The CAC includes both "General Members" and "Supporting Members." General members include city and county governments that have made specific commitments to implement measures in support of the region's air quality plan and appoint an elected official to serve as a voting representative at CAC meetings. Supporting members include any organization that takes action to support the purpose of the CAC and reports their actions periodically to the CAC.

The CAC has an advisory committee that consists of staff members from each CAC member organization. 


The Clean Air Coalition meets at a time, date and place specified by the Coalition Chair, generally the second Wednesday of selected months. Meetings are open to the public and announced on CAPCOG's website once scheduled.

The Ozone Advance Program (OAP)

In December 2013 The Clean Air Coalition adopted a ozone Action Plan. As part of the OAP Action Plan, 30 entities, including Coalition members and other participating organizations, made more 500 commitments to implement measures such as:

  • commute reduction programs
  • development policies
  • energy and resource efficiency measures
  • fleet and fuel efficiency measures
  • outreach, awareness, and education measures
  • regulation and enforcement measures
  • sustainable procurement and operations measures
  • other actions to help reduce emissions or ozone exposure

Each participating organization selected measures appropriate for their own organization and community. Their contributions are varied reflecting the creativity and unique resources of the organizations.

The Clean Air Coalition has been a national leader in voluntary air quality planning efforts, and these plans have served as models for other regions. EPA awarded the Coalition a Clean Air Excellence Award for Community Engagement in 2014 in recognition of these efforts.
