The 2026 World Cup, to be held in the US, Canada and Mexico, could become the most polluting tournament in football history. That is the warning from FIFA's Climate Blind Spot, a report outlining how the expanded format, geographical spread and reliance on air travel will sharply increase its climate impact.
According to the study, produced by the New Weather Institute, this year's World Cup will generate at least nine million tonnes of CO₂ equivalent, almost double the average for tournaments held between 2010 and 2022, which was around 4.7 million. In broader scenarios, that figure could rise to 15 million tonnes, making the event one of the most polluting in the history of sport.
