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.
CO2 利用技术的可持续性评估应包括经济、环境和社会方面。虽然已经提出了 CO2 利用（CDU）的经济和环境评估指南，但 CDU 的社会评估方法尚未确定。本文系统地研究了 CDU 的社会影响评估，得出了一个方法论框架，并给出了应用实例。研究发现，无论是过程还是部署情景，都是评估的关键因素，而原材料的来源则被观察到是评估 CDU 技术中社会影响的热点。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，该框架为 CDU 的整体可持续性评估方法的发展提供了一个新的方面。因此，三重螺旋方法将能够探索环境、经济和社会影响之间的权衡，最终为 CDU 的开发和部署做出更有效的决策。
