Abstract
Hosting a mega-event such as the 2022 FIFA Men's World Cup is a defining moment for Qatar, a country that is in transition, small in size and population, and rich in natural gas reserves. It is a unique opportunity to host a universal event and leave a sustainable positive legacy for the country. However, the preparation, execution, and after-effects of such events are challenging initiatives with significant long-term impacts on the economy, society, and environment in the hosting country and nearby region. This study addresses the intersection between mega sports events and sustainability, to systematically compare and learn from past mega-events and apply that to the case of the Qatar 2022 World Cup. The Qatari bid proposed a new FIFA Men's World Cup (WC) spatial compact model around just one city area and the goal of achieving the first carbon-neutral WC. Herein, the challenges, opportunities, and progress in this scenario are evaluated accordingly, showing that local organizers are applying green technologies, urban development concepts, and strongly upholding the idea of legacies based on the Qatar National Vision 2030, which envisions sustainable development of the country. However, additional work is still needed to reduce environmental impacts and on several reported social issues.
