Marginal climate change abatement costs in Swiss dairy production considering farm heterogeneity and interaction effects

Climate change mitigation in the agricultural sector is a key policy goal. Marginal abatement cost curves allow comparing cost-effectiveness of greenhouse gas measures. Existing studies often do not account for heterogeneity farms and interactions between The objective this study to present new approach that allows calculation marginal curve considers farm level interaction effects climate We assess influence structural on potential corresponding costs when measures are implemented jointly level. use bio-economic model FarmDyn simulate farm-specific set mixed dairy Swiss case region (n = 66) develop an calculate bottom-up, based our sample farms. Simulation results used identify quantify effect heterogeneous structures (e.g., size, land use, etc.) using regression analysis. In study, reduce by 7% overall 3% compared stand-alone consideration four Our analysis how underlying affect shows complex processes can have ambiguous (i.e., increasing or decreasing emissions). conclude provide important knowledge about affects interact with each other. Knowledge effectiveness efficiency their improves understanding development bottom-up curves, which represent widely tool inform policymakers stakeholders cost-efficient cost-effective agriculture.
