For the first time in the history of FIFA (Fédération Internationale de Football Association), the football (soccer) World Cup held in Germany 2006 specifically addressed environmental concerns. By doing so, the German Organizing Committee did not have the objective of creating a short-term vision, but rather of making a long-term and lasting contribution to the improvement of environmental protection in hosting a mega-sporting event. By taking the football world cup in Germany as a case study, we will provide insights into the so-called ‘Green Goal’ programme and its four main areas: water, waste, energy, and transportation. From a global point of view, climate protection was added by the Organizing Committee as the fifth area of action and was recognised as a cross-sectorial task. Finally, questions are addressed on how to apply those measurements in the planning and organisation of other mega (-sporting) events.
