我们的社会依赖于生态系统服务（ES）的持续供应，而这种供应受到人类活动的负面影响。最近，一些作者提出了生命周期评价（LCA）研究的评价指标，并开发了相应的表征因素，集成在LCA的影响评估阶段（LCIA）。然而，这些指标中的绝大多数仍然没有可操作性，没有一项研究提出了一个全面的环境服务清单，供列入伦敦国际评估。因此，将环境服务纳入伦敦国际投资评估的个别努力缺乏一个框架的指导，无法全面评估环境服务并确定其纳入伦敦国际投资评估的优先次序。这项研究解决了上述知识差距，并提出了一个原始的框架，在LCIA的ES的最佳覆盖范围。我们首先识别、描述和可视化目前（直接和间接）评估的生态系统服务，包括在广泛应用的LCIA方法ReCiPe2016中。接下来，我们提出了一个最佳的覆盖范围ES在LCIA组成的15类ES，包括供应，监管和维护，文化服务，来自ES分类方法CICES V5.1。接下来，我们确定当前和最佳覆盖范围之间的差距，包括ReCiPe2016目前未覆盖的11个ES类别。作为一个建议，以帮助加快纳入失踪的ES，我们最终优先使用现有的货币估值数据的失踪类别，从而在ES类别的排名将被列入LCIA。排名最高的四个类别是“流量调节和保护免受极端事件”，“废物，有毒物质和滋扰的调解”，“水条件”和“美学价值”。我们的分析和优先次序有助于为科学界制定研究议程，以协作和全面地将LCIA中缺失的ES类别纳入其中。(C)2019由Elsevier Ltd.出版
Our society relies on the sustained provisioning of ecosystem services (ES), while such provisioning has been negatively affected by human activities. Recently, several authors proposed indicators for the assessment of ES in Life Cycle Assessment (LCA) studies and developed corresponding characterization factors for integration in the impact assessment phase of LCA (LCIA). However, the vast majority of these indicators are still not operational and not a single study has presented a comprehensive list of ES for inclusion in LCIA. As a result, the individual efforts to incorporate ES in LCIA lack guidance from a framework to comprehensively assess and prioritize ES for inclusion in LCIA. This study addresses the aforementioned knowledge gap, and presents an original framework for the optimal coverage of ES in LCIA. We first identify, describe and visualize ecosystem services assessed currently (directly and indirectly) included in the widely applied LCIA method ReCiPe2016. Next, we propose an optimal coverage of ES in LCIA consisting of 15 categories of ES, including provisioning, regulation and maintenance, and cultural services, derived from the ES classification method CICES V5.1. Next, we identify the gap between the current and optimal coverage, consisting of 11 ES categories currently not covered by ReCiPe2016. As a proposal to help accelerate the incorporation of missing ES, we finally prioritize missing categories using available monetary valuation data, resulting in a ranking of ES categories to be included in LCIA. The four categories that rank highest are "Regulation of flows and protection from extreme events", "Mediations of wastes, toxics and nuisances", "Water conditions" and "Aesthetic value". Our analysis and prioritization helps setting a research agenda for the scientific community to collaboratively and comprehensively incorporate missing ES categories in LCIA.
