This document regroups all the results for energy and greenhouse gas (GHG) in a network of 120 farms in Germany, Italy, Spain and France, that were followed during 3 years by the partners of the AgriClimateChange program. The manual presents in a progressive way: the general principles of the ACCT evaluation tool, the energy-GES results per production system, the main measures to reduce energy and GHG on the farms. Finally 9 specific case studies are detailed, corresponding to contrasting production systems.
