Methane Mitigation Incentives and Livestock Production Impact

This research article assesses the impact of methane mitigation incentives on livestock production in California from 2016 to 2025. It documents how public subsidies for methane capture infrastructure, particularly for dairy farms, may inadvertently lead to increased facility growth. The study utilizes facility data and satellite imagery to analyze the relationship between biogas capture incentives and the expansion of dairy operations. The findings indicate that the anticipation and receipt of these incentives are associated with an increase of approximately 860 mature dairy cows per facility over three years. The article outlines California's key policies, including the Dairy Digester Research and Development Program and the Low Carbon Fuel Standard, which provide financial incentives for methane capture. It also details the research methodology, including statistical matching techniques and satellite imagery analysis, to estimate the causal relationship between digester adoption and dairy expansion. The implications of these findings for policymakers are also discussed, emphasizing the need for careful design of methane mitigation incentives.
