On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Ce module fait partie dune série de power points visant à décrire la structure et le fonctionnement de loutil EX-ACT. EX-ACT (Ex-Ante Carbon-balance tool) est un outil développé par lOrganisation des Nations Unies pour lAlimentation etlAgriculture (FAO). Il vise à apporter des estimations de limpact des projets de développement agricoles et forestiers sur les émissions de Gas à effet de serre et la séquestration de carbone, indiquant leurs effets dans un bilan carbone. Il sagit dun système basé sur lutilisation des terres, associée à ladoption de gestion et de pratiques alternatives (Voir le flyer de loutil EX-ACT ). Loutil adopte une approche par module, chaque module étant décrit dans un power point comme celui-ci. A propos

On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Glossary On-line resource materials for policy making Ex-Ante Carbon-balance Tool Global warming potential (GWP) is a measure of how much a given mass of greenhouse gas is estimated to contribute to global warming. It is a relative scale which compares the gas in question to that of the same mass of carbon dioxide (whose GWP is by definition 1) Emission factor: normalized coefficient that allows for calculating the emission fluxes of GHG Carbon sink: system that absorb naturally a part of the CO 2 emitted in the atmosphere and store carbon during a more or less long term Carbon balance: should be considered, for a specific project (or scenario of action) in comparison with a reference, as the net balance of all GHG emissions expressed in CO 2 equivalent (sources and sinks) with the atmosphere interface and the net change in C stocks (biomass, soil…).
