Le besoin en matières de l’économie française qui est de 15 t/hab. en 2010, s’élève à 22 t/hab. en équivalent matières premières (y compris les ressources utilisées à l’étranger pour les importations) et à 40 t/hab. au moins en tenant compte des mouvements de matières inutilisées (terres excavées lors des travaux de construction, érosion). Ainsi, pour une voiture, dont la fabrication comporte un grand nombre d’étapes, l’ensemble des matières premières extraites représente 7 à 10 fois son poids. Sur l’ensemble de la consommation française, environ 35 % des matières premières mobilisées pour la satisfaire le sont à l’étranger.
The hidden face of materials mobilised by the French economy
The per capita material input of France's economy, 15 tonnes in 2010, rises to 22 tonnes per capita when considered in raw material equivalent terms (i.e. including resources used in other countries for imports) and to 40 tonnes per capita when movements of unused materials (excavated for construction, eroded agricultural soils, etc.) are taken into account. Thus, for a car, whose manufacture involves numerous stages, the total of raw materials extracted amounts to between 7 and 10 times the weight of the vehicle. Around 35 % of the raw materials needed to satisfy all of France's consumption are mobilised in other countries.
