Sustainability assessment has emerged as a critical sub-field within CDU. This spawns the question; ‘What is the optimal supply chain-oriented approach to exploratively and holistically evaluating sustainability?’. Guidelines targeting isolated LCAs, TEAs and SIAs currently prevail, predominantly neglecting their integration [1]. This shortcoming is commonly manifested in inter-strand burden shifting. An ISO14K aligned framework is needed for holistic, modular, macro-level assessments of complex and circular supply chains. Building upon the ‘triple helix approach for CO2 utilisation assessment’ [2], a novel ‘hub and spoke’ framework is developed, reducing both time and resource intensity. Assessments are built around interchangeable modules, incorporating MCDA-derived value choices to align sustainable development with business, political and social pressures. Producing comparative, subjective supply chain rankings, alongside more traditional objective results. Generated models are non-practitioner friendly, enhancing communicability, decision making, and progression towards crucial international climate targets.
