With increasing concern regarding global climate change, there is a growing need to ensure responsible management practices for mega events that take cognisance of the realities and challenges regarding this phenomenon. The existence of a relationship between the tourism industry and climate change has only recently been addressed by researchers. This study explores the potential impacts of mega events on climate change, with particular reference to the 2010 Soccer World Cup. The methodology used for this study was in-depth personal interviews conducted amongst key stakeholders in the Tshwane Metropole, South Africa. A combined use of purposive and snowball sampling was used to identify the target population. A key finding of the study was that the various stakeholders are not aware of the contributions their operations make to climate change. However, when these contributions are linked to an event such as the 2010 Soccer World Cup, greater consideration is given to this phenomenon in their business operations. This study indicates that it is of crucial importance to consider and responsibly manage the impacts that mega events can have on climate change. Based on this study it is suggested that appropriate environmental management strategies and guidelines are developed, not only for individual stakeholders, but also for all industries in South Africa in order to ensure that operations are conducted in a sustainable manner.
