A new report from the New Weather Institute estimates the 2026 FIFA World Cup could generate between 9 and 15 million tons of carbon dioxide equivalent, making it the most carbon-intensive sporting event ever. The tournament spans 16 host cities across three countries, with 48 teams playing 104 matches, 63% more than previous editions. Aviation alone is expected to produce over 7.7 million tons of CO2, with flight emissions 160% to 325% higher than earlier World Cups. Critics argue that FIFA's sustainability commitments conflict with the decision to expand the tournament and rely heavily on air travel. The report calls this a 'climate blind spot' and warns that efficiency measures like greener stadiums and public transit will not offset the structural emissions from long-distance travel. The lack of high-speed rail in North America makes the problem worse, shifting environmental costs onto the public.
