Soccer fans are increasingly watching preparations for the 2026 World Cup through their fingers. The most popular sporting event on the planet is awash in controversy, whether it’s the eye-watering ticket prices, the question of Iran’s participation while the president of one of the host countries threatens war crimes against it, or the role that US Immigration and Customs Enforcement may or may not play in policing the event. And yet, lost in the political pyrotechnics is a fiasco that carries as much long-term peril as any: the tournament’s staggering contribution to runaway climate change.
The 2026 World Cup is not only the most politically combustible tournament in modern history, but it is also on track to be the “most polluting” World Cup ever, with total greenhouse gas emissions hitting nearly two times the historical average. Scientists conservatively project that the tournament will generate around 9m tons of carbon dioxide equivalent. Air travel comprises approximately 7.7m tons of this carbon budget, and more than four times that of the average for tournaments held between 2010 and 2022. The researchers note that the worst-case upper estimate for air transport is about 13.7m tons of CO2. That may sound bad, but that’s just because World Cup emissions have never been worse.
