The San Joaquin Valley Air Pollution Control District has just released a digital highlights summary of its 2025 Annual Report. You can access the report in English here and in Spanish here.
The report summarizes air quality progress, pollution levels, control efforts, and much more that has resulted in Valley air quality to be cleanest on record.
Said Samir Sheikh, Executive Director and Air Pollution Control Officer: "Based on air monitoring data collected throughout the region, 2025 was the cleanest year on record across numerous air quality metrics. For the first time, every federal reference monitoring site recorded levels below the federal 24-hour PM2.5 standard. At the same time, we continued to make meaningful progress in reducing ozone concentrations with the lowest number of exceedances of ozone standards on record. Overall, the Valley continued to have more “Good” air quality days, and a record low number of only five “Unhealthy” days across all Valley counties, down from over 100 days just ten years ago, and hundreds of days twenty years ago. These improvements bring the Valley closer than ever to attaining the remaining federal health-based standards, and represents real improvements in the air we breathe and tangible health benefits for the communities we serve."
The report summarizes, permit actions, grants & incentives, partnerships, air quality monitoring, rewards, and general information about the Valley Air District.
