California funds 18 dairy digester projects


The California Department of Food and Agriculture has awarded $35.2 million to 18 dairy digester projects. The projects are part of the Dairy Digester Research and Development program and aim to reduce greenhouse gas (GHG) emissions from manure at California dairy farms.

“California continues to the lead the nation in supporting smart climate programs that address on-farm challenges and promote agricultural sustainability,” said CDFA Secretary Karen Ross. “I applaud our dairy farmers for proactively addressing climate pollutants and reducing overall greenhouse emissions to help meet the state’s climate goals.”

Financial assistance for the installation of dairy digesters comes from California Climate Investments, a statewide initiative that uses Cap-and-Trade program funds to support the state’s climate goals. CDFA and other state agencies are investing these proceeds in projects that reduce GHG emissions and provide additional benefits to California communities. Dairy digester grant recipients will provide an estimated $71.2 million in matching funds for the development of their projects.

Additional information on the 18 awards is available on the CDFA website.
