Abstract
Transitioning to a circular economy (CE) may create unintended social consequences. This systematic review analysed 45 published studies from 2009 to 2023 that evaluate these consequences using social lifecycle assessment (S-LCA), a tool based on the UNEP Guidelines. Most studies focused on circular activities like energy recovery and material recycling rather than reuse, remanufacturing, and repair. Worker-related issues like health, safety or fair wages were more frequently reported than impacts on consumers or society. Challenges in S-LCA application for CE include defining system boundary, identifying affected stakeholders, selecting relevant impact categories and indicators, obtaining verifiable data inventory, and addressing subjectivity in impact interpretation. A solution identified through the review was to enhance stakeholder involvement across industries to identify emerging social risks during the transition to CE. Periodically revising the UNEP Guideline based on these risks will provide a uniform framework for continued use of S-LCA in evaluating the transition to CE.
