For more than 25 years, Air Alliance Houston’s staff has 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 aim to empower Houstonians to take charge of their health and environment.


1988: A few concerned citizens join 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 becomes a Texas nonprofit corporation in 1992.

1995: GHASP receives 501(C)3 tax-exempt status.

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

1997: Mothers for Clean Air receives 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 is renamed as 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.
