Abstract Although methodological development of Life Cycle Sustainability Assessment (LCSA) is still under discussion, an increasing number of case studies have been published in recent years. A necessity to strengthen methodological trade-offs and obtain a consistent basis for future LCSA case studies exists. The aim of this research is to identify how LCSA is being applied for each of the pillars of sustainability (environmental, economic and social) and how results are being integrated into the decision-making process. To achieve this aim, a systematic review of case studies was conducted. The methodology followed includes research questions to guide the process, search guidelines for selecting case studies to analyse and assessment rules to identify information to extract. The descriptive and content analyses of case studies provided key findings related to the main goals, divergences in the scope of the pillars of sustainability, data collection sources, the most readily applicable impact indicators for each of the three pillars of sustainability, operational research methods applied as drivers for communication and decision processes. In addition, the incipient interactions between LCSA and new sustainability approaches as circular economy and Sustainability Development Goals (SDG) is analysed. As a final conclusion, further research should be carried out to achieve consistency in the selection of the scope for each pillar of sustainability. This would make it possible to develop more accurate indicators for quantifying the social impact and to point out advantages and disadvantages of operation research methods for communication and support in decision-making.

生命周期可持续性评估：案例研究的经验教训

摘要 尽管生命周期可持续性评估（LCSA）的方法论开发仍在讨论中，但近年来已经发表了越来越多的案例研究。有必要加强方法论的权衡并为未来的 LCSA 案例研究获得一致的基础。这项研究的目的是确定 LCSA 如何应用于可持续性的每个支柱（环境、​​经济和社会）以及如何将结果纳入决策过程。为了实现这一目标，对案例研究进行了系统回顾。遵循的方法包括指导过程的研究问题、选择案例研究进行分析的搜索指南和评估规则以识别要提取的信息。案例研究的描述性和内容分析提供了与主要目标、可持续性支柱范围的分歧、数据收集来源、可持续性三大支柱中最容易适用的影响指标、应用的运营研究方法相关的关键发现作为沟通和决策过程的驱动因素。此外，还分析了 LCSA 与循环经济和可持续发展目标 (SDG) 等新可持续性方法之间的初步相互作用。作为最后的结论，应该进行进一步的研究，以实现可持续性每个支柱范围选择的一致性。
