摘要

行星边界(PBs)的开创性方法从安全操作空间(SOS)的角度定义了环境的可持续性,以促进人类社会的发展和繁荣。该方法与生命周期评估(LCA)--一种评估产品系统对环境影响的标准化方法--相结合,找到了肥沃的土壤。在本文中,我们将对现有的将 PB 嵌入 LCA 的方法进行详细回顾。我们首先探讨了 PBs 控制变量与 LCA 影响类别之间的联系,然后重点回顾了三种方法:(i) 绝对环境可持续性评估 (AESA);(ii) 基于 PBs 的归一化;(iii) 基于 PBs 的加权。我们研究了四种关键的方法,包括单位的协调(PBs 控制变量和 LCA 指标之间的协调)、SOS 的定义和分配、边界的区域化和时间方面。最后,我们就适用性、局限性、政策影响和结论进行了讨论。

Approaches to incorporate Planetary Boundaries in Life Cycle Assessment: A critical review

The Planetary Boundaries (PBs) pioneering approach defines environmental sustainability in terms of a Safe Operating Space (SOS) for human’s society to develop and thrive. The approach has found fertile ground in combination with Life Cycle Assessment (LCA) - a standardised method for assessing the environmental impacts of product systems. In this article, we conduct a detailed review of existing approaches to embed PBs in LCA. We start by exploring the links between PBs control variables and LCA impact categories and then focus on reviewing three approaches (i) absolute environmental sustainability assessment (AESA), (ii) PBs-based normalisation and (iii) PBs-based weighting. We examine four key methodological aspects covering harmonisation of units (between PBs control variables and LCA indicators), definition and allocation of the SOS, regionalisation of boundaries and temporal aspects. We conclude the review with a discussion on applicability, limitations, policy implications and conclusions.
