Possible target corridor for sustainable use of global material resources

摘要: Many countries have started to develop policy programs for the sustainable use of natural resources. Indicators and targets can cover both a territorial life-cycle-wide global perspective. This article focuses on how safe operating space material resource be outlined based existing economy-wide flow indicators. It reflects issues such as scale systems perspective, choice indicators determines target "valves" socio-industrial metabolism. considers environmental pressures social aspects fair use. Existing proposals consumption are reviewed, partially revisited, taken basis outline potential values extraction minerals biomass by final consumption. A sustainability corridor is derived with Total Material Consumption abiotic resources ranging from 6 12 t/person, biotic not exceeding 2 Raw used materials 3 t/person until 2050. For policy, "10-2-5 triplet" provide orientation, when three assigned 10, 2, 5 respectively.
