EX-ACT Value Chain (EX-ACT VC) is derived from the Food and Agriculture Organization of the United Nations (FAO) EX-Ante Carbon-balance Tool (EX-ACT). The tool is based on the Intergovernmental Panel on Climate Change (IPCC) methodology to account for GHG emissions of primary agricultural production, augmented with methodologies from peer reviewed literature to cover the remaining sectors and actors in the value chain. EX-ACT VC is free to download and is Excel-based.
