Experts predict the 2026 World Cup will be the most polluting sporting event in history. Expanding to 48 teams across North America significantly increases CO2 emissions due to the massive distances fans and athletes must fly between venues. While previous events like the Paris Olympics have reduced their footprints, FIFA's growth strategy creates a cycle of higher emissions. Analysts estimate the event could generate between five and nine million tonnes of CO2, far exceeding previous tournaments.
