California Air Resources Board

To better understand emissions trends in the State's dairy sector, CARB staff utilized data sources from Federal, State, and Local agencies to develop the California Dairy and Livestock Database (CADD). The database contains facility-level cattle population and digester information for California dairies from 2012 to 2022. CADD is based on publicly accessible documents and improves CARB's ability to track the California dairy and livestock sector trends. For additional information, please contact CADD@arb.ca.gov.
