The state considers natural gas produced at dairies to be carbon negative, because digesters capture planet-warming methane that would otherwise be released from farms and operators then sell it to end users who would ordinarily buy fossil fuels. But modeling released this summer shows that the state could meet its climate transportation goals without such generous credits for biogas. Now, for the first time in years, California is considering changes to the credit program that helps support digester projects. The stakes are high for both those living near dairies and the industries that have benefited from the incentives; the process could decide whether California continues subsidizing the projects. According to regulatory documents released in December, the state appears set to keep the credits in place for two decades.
