Greenwashing in sport? This accusation has been increasingly levelled at clubs and associations in recent years. In their article in SpoPrax 1/24, David Menz, Dr Tinusch Jalilvand and Juliane Schneider shed light on the legal framework that underpins, but can also refute, the accusation of unfair representations of one’s own environmental performance. The topic will continue to gain in importance, particularly as a result of the planned (and in some cases already adopted) regulation of “green claims” at European level. Stakeholders in the world of sport should therefore carefully consider whether and how they go public with environmental claims about their own activities.
