California launches mobile air monitoring for pollution-affected communities

California has launched a pioneering initiative to address air pollution in underserved communities. The Statewide Mobile Monitoring Initiative (SMMI), announced by Governor Gavin Newsom, aims to collect detailed air quality data using specially equipped vehicles. This data will guide efforts to improve air quality and public health across the state.

Governor Newsom highlighted California's leadership role in environmental protection, stating, “While the federal government threatens to take us back to the days of smoggy skies and clogged lungs, California continues to lead the way.” The initiative targets 64 communities that have faced significant environmental challenges.

The program is spearheaded by the California Air Resources Board (CARB) and involves partnerships with Aclima and researchers from the University of California, Berkeley, University of California, Riverside, and Aerodyne. These partners will deploy sensor-equipped vehicles and mobile laboratories for data collection.

Part of the broader California Climate Investments effort, this project emphasizes serving low-income communities disproportionately affected by pollution. More than 60% of monitoring will focus on these priority populations.

Dr. Steven Cliff, CARB Executive Director, emphasized community involvement: “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.”

Monitoring will occur over a year until June 2026. Collected data will be made publicly available and used by various stakeholders to address pollution concerns. It may also inform future regulatory programs and academic research.

The initiative is supported by over 40 community-based organizations working with CARB to ensure local concerns shape monitoring efforts effectively.

Over five decades, California’s clean air initiatives have significantly reduced health costs related to illness and cancer risk from diesel emissions. The state continues its clean energy advancements under Governor Newsom's administration.
