World Cup Fans Drive 80% of Tournament Emissions, Study Finds
Major events like the FIFA World Cup and global concert tours generate billions in economic value and bring people together. But a new study from the University of Cambridge, published in Communications Sustainability, reveals a sobering trade-off: the travel, construction, and consumption tied to these spectacles produce massive greenhouse gas emissions. The researchers propose a new metric called “climate viability” to weigh the benefits against the environmental cost.
The study focused on the 2026 World Cup and Coldplay’s 2024 European tour. For the World Cup, the expansion to 48 teams is expected to push total emissions to roughly 4.23 million metric tons of CO2 equivalent—on par with Iceland’s annual output. Eighty-two percent of that comes from fan travel, with international flights alone accounting for 3.07 million tons. If those climate costs were added to ticket prices, each match ticket would cost an extra $114 on average. Coldplay’s tour, by contrast, showed how fan behavior can make a difference: 98% of emissions cuts came from fans choosing greener travel, helped by a dedicated app and merchandise discounts. The band’s overall emissions were 46% lower than a typical tour.
The researchers propose a two-stage economic framework. First, compare the event’s economic benefits—measured by ticket demand and organizer revenue—against the monetary cost of emissions. If the cost outweighs the benefits, organizers should consider scaling back or canceling. For both the World Cup and Coldplay’s tour, the benefits exceeded the costs, though the World Cup’s calculation becomes uncertain if the social cost of carbon is on the high end. The second stage calls for sharing indirect emissions costs—like fan travel—between organizers and spectators. Suggestions include offering discounts for low-carbon travel, selecting host cities closer to major visitor populations, and imposing a carbon levy on higher-tier tickets. A broadcasting fee of $4.50 per viewer could offset the World Cup’s total estimated carbon cost of $787 million.
“We now regularly see record-breaking temperatures as a result of climate change, which will limit if and how these mega-events can be staged in future,” said Cambridge professor Shaun Larcom. “If hugely popular blockbuster events cannot take responsibility for their emissions, it gives little hope for elsewhere.” The study’s coauthor, Jackson Goldman, emphasized that these events generate enough welfare to justify their emissions—but only if organizers and fans work together to cut them. The message is clear: the party can go on, but the bill for climate damage can no longer be ignored.
