Because clean air is a right—not a privilege.
In Central California, entire communities are living with the health and economic toll of air pollution, climate stress, and environmental injustice. The San Joaquin Valley consistently ranks among the most polluted regions in the United States, with asthma rates among the highest in the country. Children miss school. Parents miss work. Families suffer—simply because of where they live.
At the Central California Asthma Collaborative (CCAC), we’re changing that reality—through care, advocacy, and data-driven solutions.
We serve the heart of California with a heart-centered mission:
Advancing health equity and environmental justice by empowering Central California communities to reduce the burden of asthma.

Why Central California Needs You
The San Joaquin Valley is one of the most polluted and underserved regions in the U.S.—despite feeding the nation and powering its economy. The burden is heavy, but together, we can lift it.
Asthma care
Nearly half of the U.S. population lives with unhealthy levels of air pollution.
Health Equity
People living in poverty are more likely to live in close proximity to sources of pollution and have fewer resources to relocate.
Decarbonization
A changing climate is making the job of cleaning up the air more difficult.
Environmental Justice
Fresno-Hanford-Corcoran and Los Angeles-Long Beach, California, posted their lowest levels of particle pollution ever, though they are still among the worst five.
Real-Time Air Quality Monitoring
46% of the population—are living in counties with failing grades for ozone or particle pollution.
Policy Advocacy
The Lung Association urges defending EPA programs and staffing, warning that cuts threaten essential air monitoring and pollution control needed to safeguard public health.
