The purpose of this paper is to assess how stakeholders perceive sustainability in sport events. In total, a material of 270 interviews from four groups of stakeholders was collected, aggregated and analysed. Four factors directly related to sustainability are identified and analysed which illustrate differences across stakeholder groups in the perception of sustainability efforts associated to the sport event. The research contributes to the event management literature by furthering the understanding of sustainability in events by offering a model including four factors governing the perception of sustainability from a green perspective, from a branding perspective, from a transport and from a communication perspective.
