A traceability system is an increasingly important tool within the agri-food sector. It provides infor-mation visibility across the supply chain. Nevertheless, information provided by most traceability sys-tems is related to food quality and safety. Environmental and broader social related information is lim-ited. In this research-in-progress paper, we applied affordance theory to propose a research model that explains how an electronic-based traceability system provides possibilities for actions/affordances which can be actualised to achieve sustainable supply chains that create economic, environmental and social benefits simultaneously. In this paper, we first identify affordances provided by the traceability system investigated and explain various factors that affect their actualisation. Then we develop a model based on an extensive analysis of literature and interviews with manufacturers and suppliers involved in three food supply chains in Indonesia. The paper also provides practical guidance for implementing an electronic traceability system to transform food supply chains to make them more sustainable.
