Experts from the University of Lausanne predict the 2026 FIFA World Cup will produce 9 million tons of CO2, far exceeding previous tournaments. The increase is driven by an expanded field of 48 teams and the logistical challenge of hosting matches across the USA, Canada, and Mexico. The environmental impact is primarily linked to long-haul flights for millions of fans and delegations. Concerns are growing as FIFA plans further expansion for the 2030 World Cup, which will span three continents.
