The presence of the 2 million or so fans who will travel from abroad to attend the Paris 2024 Olympic games will be felt in the city’s stadiums. Unfortunately, it will also be felt by the climate.
According to Olympic organizers, around a quarter of the carbon emissions associated with holding the world’s biggest sporting event will be generated by spectator travel.
It’s a longstanding problem that didn’t originate with the Paris Olympics. But Paris, like previous games, has embraced sustainability as a core principle. Along the way, it’s made good progress in reducing greenhouse gas emissions related to venue construction and operations. But it’s done little to address overseas spectator emissions.
There is an attainable, if radical, solution that would make future games far more enjoyable and accessible: Keep it local. Limit most ticket sales to residents of the host city and surrounding areas, while providing some access to regional fans who travel most sustainably.
The argument for taking action is clear: At the 2012 London games, spectator-related emissions, most of which were air travel-related, clocked in at 913,000 metric tons, or 28% of the 3.3 million tons of carbon emitted during the games (that’s equivalent to the annual emissions of about 696,000 typical American cars). Four years later, the organizers of the 2016 Rio Olympics estimated that overseas spectator travel would generate a massive 1.72 million metric tons, or 38% of the emissions associated with the games (final numbers were never released).
While it would no doubt be scary for the International Olympic Committee to take on travel-generated emissions, the organization does have a real-life example of the impact it could create: Tokyo 2020.
