An evaluation of the sustainability of the Olympic Games

The Olympic Games claim to be exemplars of sustainability, aiming to inspire sustainable futures around the world. Yet no systematic evaluation of their sustainability exists. We develop and apply a model with nine indicators to evaluate the sustainability of the 16 editions of the Summer and Winter Olympic Games between 1992 and 2020, representing a total cost of more than US$70 billion. Our model shows that the overall sustainability of the Olympic Games is medium and that it has declined over time. Salt Lake City 2002 was the most sustainable Olympic Games in this period, whereas Sochi 2014 and Rio de Janeiro 2016 were the least sustainable. No Olympics, however, score in the top category of our model. Three actions should make Olympic hosting more sustainable: first, greatly reducing the size of the event; second, rotating the Olympics among the same cities; third, enforcing independent sustainability standards. Sustainability has been added as a 'pillar' of the Olympic movement, but this analysis examines each Summer and Winter Games since 1992 to find that the performance of host cities across a range of indicators has been declining over time.

Automated summary

The study found that the overall sustainability of the Olympic Games is moderate and has declined over time. Salt Lake City 2002 was the most sustainable Olympic Games, while Sochi 2014 and Rio de Janeiro 2016 were the least sustainable.
