Mega-events such as the FIFA World Cup and blockbuster concert tours are far more climate-intensive than most people assume, according to new research from the University of Cambridge. The study argues that the dominant emissions source is not energy used at venues, but the carbon cost of getting the audience to and from the event.
For the 2026 FIFA World Cup, Cambridge researchers estimate a total footprint of about 4.23 million tonnes of CO₂ across the tournament, when competition expansion to 48 teams is modelled. Crucially, travelling spectators drive this total: roughly 82% of emissions are attributed to fan travel, including about 3 million tonnes from flying alone.
The team further notes that if organisers simply priced climate mitigation directly into tickets, the additional cost could average around $114 per match. That figure is used to motivate a different approach: reduce spectator travel emissions instead of trying to offset them after the fact.
The findings draw an instructive parallel from Coldplay’s 2024 European tour. Using ticket and travel-related data from 32 concerts in ten cities, the researchers estimate that passing tour climate costs to fans would add about $11 per ticket. Importantly, the tour already showed meaningful behavioural change.
Although the band implemented venue-adjacent measures such as solar-powered stage systems, the study finds that almost all emissions reduction came from fans voluntarily switching to lower-carbon travel. Compared with a business-as-usual tour, fan travel emissions fell by 48%, and overall tour emissions were nearly halved (46%).
To quantify “climate viability,” the researchers propose a two-step economic framework. First, they balance welfare and ticket demand against the financial costs implied by emissions. Second, they argue that climate damage should be treated as a shared responsibility, where indirect emissions—especially audience travel—are not borne only by organisers.
The researchers suggest practical levers: discounts for rail or shared transport, event location strategies that reduce long-haul travel, and carbon charges structured so that higher-end tickets absorb a larger share. They also float broadcast-related contributions, estimating that a $4.50 viewer fee could help cover the tournament’s total carbon cost (about $787 million).
They conclude that the influence of mega-events is unusually close to audiences, giving them cultural and financial leverage to shift travel behaviour. With climate change already constraining where and how large events can be staged, the authors argue that organisers and fans must co-design solutions rather than relying on venue-only fixes.
