EX-ACT tool for value chains

The new EX-ACT VC Tool: providing co-benefit appraisal of food value chain on GHGs emissions, climate resilience and income


This page provides guidance and case studies of the new EX-ACT VC (EX-Ante Carbon Balance Tool for Value Chain), recently developed by EX-ACT team. The tool is related to value chain environmental and socio-economic performance analysis. The guideline explains how to use EX-ACT VC for multi-impact appraisal generated by a value chain in terms of GHG emissions, resilience and income. Several case studies treating with upgrading specific crop-based value chain, supporting Climate Smart Agriculture practices and reducing production lost have been analyzed within EX-ACT VC.

The growing greening trend in local, national and international economy generates an increasing demand to develop sustainable and performant food value chain in order to eradicate poverty in rural areas, to increase resilience of populations and ecosystems, and to de-carbonize our global economy. Today, food value chain count for 19-29% (Vermeulen et al, 2012) of GHG emissions in the world and  1/3 of the total food loss and waste, which represents a cost of 750 billion US$ (FAO, 2013).  


Current agricultural systems, processing and transportation restrict sustainable development in the food sector. Changes have to be made and food value chain presents numerous challenges and opportunities to tackle simultaneously the multiples stakes faced by rural population, in order to break their observed under-performance.

The EX-ACT VC is mainly used for simple and short value chains appraisal in developing countries. It is a crop-based tool and uses numerous indicators to give results about climate mitigation (GHGs emissions, carbon footprint, and economic mitigation), resilience and socio-economic performances (value added, income and employment generated) of food value chain at micro and meso level (by agent, by stage and for the whole chain).
