许多国家已开始制定可持续利用自然资源的政策计划。指标和目标可以涵盖地域和整个生命周期的全球视角。本文重点讨论如何根据现有的整个经济范围的物质流量指标来概述全球物质资源使用的安全操作空间。它体现的是规模和系统视角等问题，指标的选择决定了社会产业新陈代谢的目标“阀门”。它考虑了安全和公平资源使用的环境压力和社会方面。对现有的资源消耗目标提案进行了审查和部分重新审视，并以此为基础概述了通过最终消费提取和使用矿物和生物质的安全操作空间的潜在目标值。潜在的可持续发展走廊的推导是，到 2050 年，非生物资源的总物质消耗范围为 6 至 12 吨/人，生物资源的总物质消耗不超过 2 吨/人，使用过的生物和非生物材料的原材料消耗范围为 3 至 6 吨/人。就政策而言，当三个指标分配值为 10、2 和 5 时，“10-2-5 目标三元组”可以提供方向。吨/人， 分别。
Many countries have started to develop policy programs for the sustainable use of natural resources. Indicators and targets can cover both a territorial and a life-cycle-wide global perspective. This article focuses on how a safe operating space for global material resource use can be outlined based on existing economy-wide material flow indicators. It reflects on issues such as scale and systems perspective, as the choice of indicators determines the target "valves" of the socio-industrial metabolism. It considers environmental pressures and social aspects of safe and fair resource use. Existing proposals for resource consumption targets are reviewed, partially revisited, and taken as a basis to outline potential target values for a safe operating space for the extraction and use of minerals and biomass by final consumption. A potential sustainability corridor is derived with the Total Material Consumption of abiotic resources ranging from 6 to 12 t/person, the Total Material Consumption of biotic resources not exceeding 2 t/person, and the Raw Material Consumption of used biotic and abiotic materials ranging from 3 to 6 t/person until 2050. For policy, a "10-2-5 target triplet" can provide orientation, when the three indicators are assigned values of 10, 2, and 5 t/person, respectively.
