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

California's Low Carbon Fuel Standard dairy digester program pays cattle farmers to capture manure methane and convert it to biogas, allowing petroleum companies to buy credits instead of reducing their own emissions. Researchers argue the program's carbon math is flawed: it uses a 100-year global warming potential metric for methane that obscures the trade-off between reducing short-lived methane and permitting additional long-lived CO2. The result is a system that may reduce near-term warming while locking in greater long-term warming. The author argues that carbon offsetting schemes consistently overstate real-world emissions reductions and that regulators should require industries to directly cut their own pollution rather than paying others to offset it.
