摘要

The automotive sector is a global driver of technological and economic progress, yet its social sustainability impacts remain insufficiently explored. Social Life Cycle Assessment (S-LCA) offers a framework to assess such impacts, but its application in the automotive industry faces significant methodological challenges. This study identifies and analyzes these gaps through a comprehensive literature review, complemented by stakeholder interviews, workshops and surveys with original equipment manufacturers and suppliers. The analysis was structured in accordance with ISO 14075, following the four S-LCA phases: goal and scope definition, inventory analysis, impact assessment, and interpretation. This reveals persistent issues including unclear functional units that fail to integrate certain social dimensions, limited availability of primary data within complex supply chains, and a lack of sector-specific impact subcategories, indicators, and interpretation parameters. To address these gaps, the study recommends developing automotive-specific frameworks, refining functional unit specifications, enhancing data collection strategies, and advancing impact pathway models for key interested parties. Such refinements will strengthen the methodological robustness of S-LCA, support more reliable decision-making in supply chain management, and promote equitable and sustainable practices in the automotive sector.
