有效利用和消耗自然资源是可持续发展的一项重要战略。本章讨论了评估“资源效率”的现有方法和指标，这些方法和指标超越了对材料使用量的评估，并朝着生命周期评估(LCA)中的现有指标发展。根据LCA的经典定义，自然资源包括以投入为导向的环境干预措施(例如，开采非生物资源，如石油、矿藏、化石和淡水，以及生物资源，如鱼和树木)。生命周期评价和现有的生命周期影响评估(LCIA)方法被视为衡量资源效率的良好基础。尽管有几个模型来评估生命周期评估中的资源使用和消耗，但仍然存在重要的挑战。现有的模型没有从人类用途的功能相关性的角度来充分评估资源的使用情况和可获得性。为了有效利用资源，需要处理可持续性的所有方面。还必须考虑材料使用和可获得性对环境、经济和社会的影响。与产品系统相关的资源利用和效率的评估需要转向生命周期可持续性评估(LCSA)。
Efficient use and consumption of natural resources is an important strategy in sustainable development. This chapter discusses available methods and indicators to assess “resource efficiency” beyond the assessment of the quantities of materials used and toward available indicators in life cycle assessment (LCA). According to the classical definition in LCA, natural resources encompass input-oriented environmental interventions (e.g., extraction of abiotic resources, such as oil, ore deposits, fossil, and fresh surface water, as well as biotic resources such as fish and trees). LCA and existing life cycle impact assessment (LCIA) methods are seen as a good basis for measuring resource efficiency. Despite several models to assess resource use and depletion within LCA, important challenges remain. Available models do not fully evaluate resource use and availability in the context of their functional relevance for human purposes. For the efficient use of resources, all dimensions of sustainability need to be addressed. Environmental, economic, and social implications of material use and availability have to also be considered. Assessment of resource utilization and efficiency associated with product systems needs to shift toward life cycle sustainability assessment (LCSA).
