The upcoming FIFA World Cup 2026, set to be the largest and most commercially successful edition in history is also projected to become the most environmentally damaging sporting event ever recorded according to environmental researchers.
Experts from the University of Lausanne in Switzerland warn that the tournament will produce an unprecedented carbon footprint due to its expanded format and multi-country hosting structure across the United States, Canada and Mexico.
Unlike previous tournaments, the 2026 World Cup will feature 48 teams, significantly increasing the number of matches, teams, officials and traveling supporters.
Researchers estimate that total emissions could reach between 5 to 9 million tonnes of CO₂, far exceeding the approximately 3.17 million tonnes recorded during the Qatar 2022 World Cup.
A major contributor to this environmental impact is long-distance air travel. With stadiums spread across vast geographical distances such as the 4,500 km gap between Miami and Vancouver millions of fans and teams will rely heavily on flights.
Experts also highlight that over five million fans are expected to travel internationally making transportation the largest source of emissions during the tournament.
Environmental analysts argue that while FIFA has pledged to measure and offset emissions, the rapid expansion of the tournament format directly increases its environmental cost.
Critics point out that FIFA’s decision to expand from 32 to 48 teams has significantly increased the number of matches and logistical operations contradicting global efforts to reduce emissions in large-scale events.
A 2025 study further suggests that a single World Cup match can generate 26 to 42 times more emissions than an elite domestic football match.
Some experts warn that the trend could continue into future tournaments, especially with the 2030 World Cup planned across three continents and the 2034 edition awarded to Saudi Arabia.
Despite FIFA’s sustainability commitments, researchers caution that without structural changes, the World Cup’s environmental footprint will continue to grow alongside its global popularity.
