Assessing risks in supply chains is a key activity for ensuring the resilience to appearances of common or less predictable adverse events. Such assessments are traditionally carried out based on purely economic factors, leaving out other factors like sustainability, which also encompasses environmental and social dimensions. This paper show the feasibility of supporting the sustainability of supply chains, starting from a risk modelling and simulation framework that was not initially developed with that goal in mind. We first propose an indicative list of sustainability requirements classified by stage in the supply chain organisation. Afterwards, we demonstrate how those requirements can be translated in our framework using queries on simulations that are expressed in a rich language. We then investigate on some strategies to adapt the supply chain to better cope with sustainability requirements. Our work is driven by and illustrated on a manufacturing case study.
