California's manure-to-gas climate program faces scrutiny over carbon accounting

California's Low Carbon Fuel Standard (LCFS) program, which incentivizes dairy farmers to convert methane from manure into biogas for fuel, is facing scrutiny. Critics argue the program's carbon accounting overstates emissions reductions by not accurately reflecting the differing atmospheric impacts of methane and carbon dioxide. While methane is a potent short-term greenhouse gas, carbon dioxide has a longer-lasting warming effect. Despite these concerns, California regulators have extended the program and are considering additional funding for dairy farmers, potentially prioritizing short-term warming reduction over long-term climate stability.

    Why California’s carbon manure math doesn’t add up

    Something stinks in California’s climate policies. Years ago, the state set up a system that pays cattle farmers across the country to turn the methane emitted from cattle manure into natural gas, encouraging the dairy sector to produce a gas we burn instead of one that just poll…
