The Olympic Games are the dream of many athletes. By performing, and especially by winning an Olympic medal, athletes make history. Unfortunately, in the last couple of decades this sporting mega-event has come into trouble. Due to high costs and pollution, the number of cities and states wanting to host has decreased as has the popularity of the games themselves. In response to the bad situation in which the Olympic Games find themselves, the International Olympic Committee (IOC), as the owner and organizer of the Games, decided to make moves that would improve the situation. In response to the bad situation in which the Olympic Games find themselves, the IOC, as the owner and organizer of the Games, decided to make moves that would improve the situation. The aim of this thesis is to present and analyze the current state of sustainability of the Summer Olympics, how this situation came about and what are the plans of the IOC for the future game in terms of sustainability. The thesis will also try to find out through the simulation method whether it is possible to hold sustainable Olympic Games based on the IOC strategy.
