可持续性评估是废物管理系统决策支持的重要方法。生命周期可持续性评估是实现这一目标的最有前途的工具，但它仍然缺乏正式的方法学框架。建立有效的LC SA方法的一项要求是，利益攸关方必须参与关于LC SA模式的决策，这在目前的评估中仍是一个空白。在本文中，我们制定并应用了一种与利益相关者协商的方法，以选择LCSA影响类别(在这种情况下，只关注社会和经济问题)。该方法以决策科学概念和工具为基础，重点是启发认知因果图中描绘的利益攸关方的观点。案例研究的结果说明了该方法的有益贡献，揭示了成熟的和创新的影响类别，并从利益攸关方那里获得了非常积极的反馈。一个方法论问题是确定影响类别的终点和中点水平的敏感性。该方法简单有效，不需要量化评级，受分析师观点的影响较小。
Sustainability assessment is an important approach for decision-support in waste management systems. Life Cycle Sustainability Assessment (LCSA) is the most promising tool for this purpose, but it still lacks a formal methodological framework. One requirement for establishing an effective LCSA methodology is the necessary involvement of stakeholders in decisions on LCSA models, which still constitutes a gap in current assessments. In this paper we develop and apply a methodology for stakeholder consultation regarding the selection of LCSA impact categories (focussing, in this case, only on social and economic issues). The methodology is based on decision science concepts and tools with an emphasis on the elicitation of stakeholders' perspectives depicted in cognitive causal maps. Results from a case study illustrate a useful contribution from the methodology, revealing both well-established and innovative impact categories with very positive feedback from stakeholders. A methodological issue is the sensitiveness in defining endpoint and midpoint levels of impact categories. The method revealed straightforward and effective, with no necessity for quantitative ratings and minor influence of the analysts' perspectives.
