    The Ex-Ante Carbon-balance Tool for Value Chains (EX-ACT VC) is a quantitative multi-appraisal tool that evaluates the sustainability of agrifood value chains simultaneously along several environmental, economic, and social dimensions. It analyses greenhouse gas (GHG) emissions along an agrifood value chain, from farm-gate-to-shelf, including GHG fluxes from processing and storage, to packaging and transportation; calculates a set of value-added indicators including gross production value, value-added, and net income; and estimates the number and nature of jobs created along the value chain. It also includes an estimation of food loss at each stage of the value chain; an assessment of gender and youth participation and an SDG tracker. The primary objective of EX-ACT VC is to provide decision support to design (ex-ante) and evaluate (ex-post) agrifood VC projects and policies by comparing a ‘current’ scenario with baseline information and a ‘planned’ scenario involving a future vision or goal (or implemented activities scenario in case of ex-post evaluations). EX-ACT VC helps users to quantify the sustainability performance of the selected value chain, identify the drivers of sustainability, understand how economic, social, and environmental dimensions are intertwined, and identify potential entry points for environmental and socioeconomic improvements along the selected value chain. The EX-ACT VC methodological guidelines aim at: 1) providing a comprehensive overview of the tool and helping users assess the sustainability of agrifood value chains across environmental, economic, and social dimensions using the tool; 2) describing the various methodological concepts underlying the tool to perform a value chain assessment and calculating several indicators of sustainability; 3) illustrating the structural layout of the tool, explaining data requirements, and providing step-by-step data entry guidance to perform a value chain assessment using EX-ACT VC; 4) discussing the different indicators the tool calculates and how they can be used for project and policy evaluation and design. These guidelines are intended to assist potential users of EX-ACT VC including policymakers, project managers, analysts, and researchers, among others.

    EX-Ante Carbon-balance Tool (EX-ACT) is a tool developed by the Food and Agriculture Organization of the United Nations (FAO). It is aimed at providing ex-ante estimates of the mitigation impact of agriculture and forestry development projects, estimating net Carbon (C) balance from greenhouse gas (GHG) emissions and C sequestration. EX-ACT is a land-based accounting system, measuring C stocks, stock changes per unit of land, and CH4 and N2O emissions expressed in t CO2e per hectare and year. Th e main output of the tool is an estimation of the C-balance that is associated with adoption of alternative land management options, as compared to a ‘business as usual’ scenario. EX-ACT has been developed using primarily the IPCC 2006 Guidelines for National Greenhouse Gas Inventories, complemented by other existing methodologies and reviews of default coefficients where available. Default values for mitigation options in the agriculture sector are mostly from the 4th Assessment Report of IPCC (2007). Thus, EX-ACT allows for the C–balance appraisal of new investment programmes by ensuring an appropriate method available for donors and planning officers, project designers and decision makers within agriculture and forestry sectors in developing countries. The tool can also help to identify the mitigation impacts of various investment project options, and thus provide an additional criterion for consideration in project selection. These technical guidelines for using EX-ACT aim at pro viding the user with the details of procedures and numbers used to perform calculation of C balance.

    Assessing environmental and socio-economic potential of agri-food value chains

    By analyzing agri-food value chains, policy makers and researchers are able to better understand how economic, social and environmental dimensions are intertwined. This is an important step, which allows for identification of areas for potential improvement along an agri-food value chain. 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.
