This booklet presents the results of the CECAM project (Energy and carbon content of household food consumption). The perspective chosen is that of the household food consumption in mainland France, in contrast with the food production and processing of the French territory. The results presented consider the main energy consump¬tion and greenhouse gas emissions of the average diet of the French population, taking into account the consump¬tion and emissions contained in the imports of interme¬diate or final products, and excluding exported French production. This study details the relative contributions to the total footprint derived from the main stages of the food system: agricultural production, processing, freight transport, distribution, out-of-home eating, travel for household food purchases, and food preparation in the home. We brought together data from statistics and models of agricultural production, food consumption, processing and transport. Ultimately, the aim would be to use the assessment and simulation tools developed for a fore¬sight exercise. Indeed, the combination of the models used will enable the simulation of changes in the various stages of the food system (production methods, pro¬cessing, possible relocation to France of imported prod¬ucts, transport reductions throughout the sector, supply modes, and dietary change) and to assess their impact on energy consumption and greenhouse gas emissions.
