🔬研究者:A conceptual framework for harmonizing farm-level accounting with national inventories and Scope 3 reporting, addressing allocation rules and land emissions.

🏢実務担当者:Guidance on the importance of standardized farm-level data for reliable carbon footprint reporting across supply chains.

🏛政策担当者:Arguments for internationally accepted accounting methods to avoid trade disputes and enable effective climate policy in agriculture.

The development of international accounting methodologies for greenhouse gas (GHG) emissions in agriculture is a matter of urgency, as the sector is an important contributor to climate change. Without internationally accepted methods, policy comparisons risk becoming an apples and oranges problem. This urgency is heightened by the expectation that countries will seek trade protection through environmental tariffs, given the long tradition of protectionism in agriculture. Our paper assesses the challenges stemming from the proliferation of accounting frameworks, emphasizes the necessity of reliable farm-level measurement, and proposes a conceptual framework to unify disparate embedded emissions accounting standards across agricultural supply chains. We utilize casual rapid review and structured narrative synthesis of scientific and policy literature highlighting structural issues to examine the fragmentation of current methodologies. We analyze farm-level estimates as the foundational measurement point for critical ledgers, including national inventories, corporate Scope 3 reporting, and product carbon footprints. A focused effort at farm-level harmonization is essential to foster reliability and interoperability across supply chain and regulatory initiatives. Harmonization should align farm-level approaches with national inventory methods as a pragmatic starting point. However, this effort must resolve a number of critical outstanding issues, notably developing consistent emissions allocation rules for products and co-products, and achieving consensus on land-related emissions, such as the systematic underestimation of carbon opportunity cost, and addressing the uncertainties surrounding soil organic carbon. Internationally accepted methods are crucial to prevent trade disputes arising from perceived competitive distortions. Harmonized farm-level accounting creates the necessary foundation for comparable emissions data, enabling consistent application across diverse regulatory instruments and supply chain initiatives, ultimately enabling effective climate policy. • Farm-level emission estimates are foundational but highly fragmented. • Same-farm emissions estimates can vary by over 1000%. • Accounting harmonization is urgent; differences can be used to increase protectionism. • Harmonization should align farm-level accounting with national inventory methods.
