California Air Resources Board

California's unique climate makes us a leading agricultural producer, but some of the areas with the most productive farmland of the state also suffer from the worst air quality in the nation. This not only impacts crops, but also impacts public health: 1 in 6 children living in California’s Central Valley suffer from asthma. Agricultural activities also produce climate-changing emissions, like methane.

California is working to reduce the contribution agricultural activity makes to poor air quality with sensible regulations that balance the need to address public health while protecting the economy.
