For more than 25 years, we have worked to improve the quality of Houston's air. We are committed to delivering clean air for a healthier future in Houston. Through research, education, and advocacy, we empower Houstonians to take charge of their health and environment.


1988: A few concerned citizens joined forces to form a group to prevent and eliminate smog in the Houston region. They named the group GHASP: the Galveston-Houston Association for Smog Prevention. Out of this grassroots effort, GHASP became a Texas nonprofit corporation in 1992.

1995: Received 501(C)3 tax-exempt status

1996: Another Texas nonprofit, Mothers for Clean Air (MfCA), is formed for the purpose of community-based outreach and advocacy.

1997: Mothers for Clean Air received its federal tax-exempt status

2008: GHASP and MfCA decided to join together as one organization. The previous activities of GHASP and MfCA fit together like pieces in a puzzle. The new organization combined and strengthened the goals of both organizations: to influence public policy on air quality and environmental health issues in order to protect the health of residents and improve their quality of life.

2010: the new organization was renamed Air Alliance Houston. Air Alliance Houston’s mission is to reduce air pollution in the Houston region and protect public health and environmental integrity through research, education, and advocacy.

Present & Future

The organization maintains its solid reputation for environmental and policy expertise, monitoring environmental agency performance and flagging shortcomings. When all else fails, we use litigation to compel agencies to enforce the law. Air Alliance Houston provides technical expertise to our nonprofit allies and to local and state leaders. We participate in regulatory and legislative processes, testify at hearings, and comment on proposals. We educate communities about local air pollution issues and both state and federal policy. We work with communities to bring broad grassroots pressure to bear on polluters and regulators alike.

We want cleaner air and a healthier future for all of Houston, especially our children. We focus on the adverse effects of Houston area air pollution, such as its impairment of the developing lungs of children. We continue to develop community programs to address environmental justice issues and to educate children and adults in local communities about air quality issues and prevention of exposure. We educate communities with plays, film, and interactive theater, in particular Ozone Theater, which teaches young students about air pollution—its sources, its effects on their health, and what they can do about it.

As a unified effort working with such groups such as Industry Professionals for Clean Air (IPCA), Texas Environmental Justice Advocacy Services (TEJAS), Environmental Defense Fund, Texas League of Conservation Voters, Environmental Integrity Project, Environment Texas, Public Citizen and Sierra Club-Lone Star Chapter, we are capable of developing and providing comprehensive public policy review and opinions on air quality issues. We have a network of support and collaboration—the expertise of our board members, local school districts, the City of Houston, Harris County, and many organizations such as those listed above—which allows our organization to be the Houston region’s  leading environmental health and air quality nonprofit.
