In first-of-its-kind initiative, California deploys mobile air monitoring to protect underserved communities from pollution

Starting in June, the pilot project will deploy mobile air monitoring equipment to 64 communities throughout the state, with a particular focus on communities that have long faced environmental disparities. The project spearheaded by the California Air Resources Board (CARB) will use sensor-equipped vehicles from Aclima and mobile laboratories operated by researchers from the University of California, Berkeley, University of California, Riverside, and Aerodyne to collect and analyze data on local pollution levels.

The initiative is part of California Climate Investments, a statewide effort that puts billions of Cap-and-Invest dollars to work reducing greenhouse gas emissions, strengthening the economy, and improving public health and the environment — particularly in disadvantaged communities.

More than 60% of the mobile monitoring will serve priority populations, including low-income communities and communities facing disproportionate pollution burdens. The 64 communities were consistently nominated for focused action under the Community Air Protection Program, underscoring the state’s commitment to protecting the health of Californians in areas most burdened by air pollution.

“By meeting communities where they are and listening to their concerns, we’re building an air quality monitoring system that integrates the lived experiences of the people most impacted by air pollution,” said CARB Executive Director Dr. Steven Cliff. “The Statewide Mobile Monitoring Initiative represents an unprecedented opportunity to gather the detailed information we need to better protect public health in neighborhoods that have historically borne the brunt of environmental injustice.”

Monitoring will take place in the 64 communities over the next year. The project is expected to end in June 2026, when the collected data will become publicly available.  Final results will be shared with the 64 communities, the general public, and the Board. CARB, local air districts, stakeholders, and community stakeholders will use the data to help guide efforts to address existing and emerging pollution concerns. The data is also expected to inform future regulatory programs, academic research, and applications for grants such as the Community Air Grants Program.

The program is guided by a robust community engagement framework. More than 40 community-based organizations across California have partnered with CARB to identify local air quality concerns and ensure community voices shape monitoring efforts from the ground up. 

California’s clean air leadership

Over the last 50 years, the state’s clean air efforts have saved $250 billion in health costs through reduced illness and reduced diesel-related cancer risk by nearly 80 percent.

The state continues to set clean energy records. Last year, California ran on 100% clean electricity for the equivalent of 51 days – with the grid running on 100% clean energy for some period two out of every three days. Since the beginning of the Newsom Administration, battery storage is up to over 15,000 megawatts – a 1,900%+ increase.
