South San Francisco is a diverse city in San Mateo County, located within the Bay Area Air Quality Management District. Many neighborhoods are classified as pollution-burdened and disadvantaged, facing high rates of asthma.

The city has teamed up with Aclima and the California Air Resources Board (CARB) to launch a community air monitoring project guiding future actions as a part of SMMI. Using Aclima’s advanced sensors, the project collects detailed, block-by-block data on air quality throughout the community. This provides residents with clear information about local pollution and helps guide actions to improve air quality, focusing on the areas and people most affected. 

Local organizations like Rise South City are expanding air monitoring and community engagement to guide future actions.

In April of 2025, community members and stakeholders met to discuss ongoing pollution challenges and strategies for healthier air in South San Francisco.
