Assessment of the sustainability of CO₂ utilisation technologies should encompass economic, environmental and social aspects. Though guidelines for economic and environmental assessment of CO₂ utilisation (CDU) have been presented, a methodology for social assessment of CDU has not. Herewith, social impact assessment for CDU is systematically investigated, a methodological framework derived and examples of application given. Both process and deployment scenarios are found to be key factors in the assessment and the sourcing of raw material is observed to be a hotspot for social impacts within the assessed CDU technologies. This framework contributes a new aspect to the development of holistic sustainability assessment methodologies for CDU by enabling a triple helix to be created between life cycle assessment (LCA), techno-economic assessment (TEA) and social impact assessment (SIA). Therefore, the triple helix approach will enable trade-offs between environmental, economic and social impacts to be explored, ultimately enhancing effective decision making for CDU development and deployment.

开发用于二氧化碳利用评估的三螺旋方法

CO ₂利用技术的可持续性评估应包括经济、环境和社会方面。通过 CO ₂经济和环境评估指南使用率 (CDU) 已经提出，但 CDU 的社会评估方法还没有。因此，系统地研究了 CDU 的社会影响评估，推导出了方法框架并给出了应用示例。发现过程和部署场景都是评估中的关键因素，原材料采购被认为是评估的 CDU 技术中社会影响的热点。该框架通过在生命周期评估 (LCA)、技术经济评估 (TEA) 和社会影响评估 (SIA) 之间创建三重螺旋，为 CDU 的整体可持续性评估方法的发展提供了新的方面。因此，三螺旋方法将能够探索环境、经济和社会影响之间的权衡，
