This research aims at investigating the influence of information quality on supply chain performance, from both an economic and environmental point of view, through the use of an agent-based simulation based on a real case study. We investigate the supply chain of a large European retailer that initiated the deployment of a green supply chain with its small suppliers. Such a green supply chain’s success depends on suppliers’ decision of going to the new green supply chain configuration in which both physical flows and information exchanges evolve. Consequently, volume and frequency of deliveries and quality of information exchanges are influencing their decision. The simulation also shows that green supply chain success is influenced by assimilation of the information system supporting com-plementary information sharing.
