The 2026 World Cup Doubles Its Carbon Footprint by Expanding Its Format
More than 7.8 million tonnes of CO₂ equivalent: the 2026 World Cup organized by the United States, Canada, and Mexico will produce twice as many emissions as the 2022 edition in Qatar. Carbon analysis by Greenly reveals that 87.8% of this footprint comes from spectator travel, compared to just 3.1% for stadium construction and operation.
The expanded format to 48 teams and distribution across three countries mechanically transforms the event into a machine producing transcontinental airline tickets. Simple arithmetic that raises a central question: can mega-events be made greener when their footprint depends primarily on their size?
The Essentials
- 7.8 million tonnes of CO₂e expected for 2026, compared to 3.63 MtCO₂e in Qatar in 2022
- 87.8% of emissions linked to spectator travel, only 3.1% to infrastructure
- 48 teams instead of 32, 104 matches instead of 64, spread across three countries separated by thousands of kilometers
- FIFA commitment to reduce emissions by 50% by 2030, contradicting the continuous expansion of tournaments
A Million Airline Tickets That Weigh Down the Balance
Greenly’s figures settle the debate over the real impact of major sporting events. Of the 7.8 MtCO₂e expected in 2026, spectator travel represents 6.85 million tonnes. Infrastructure—stadium construction, transport systems, accommodation—weighs only 245,000 tonnes, thirteen times less.
This distribution radically inverts environmental priorities. Building ecological stadiums or installing solar panels remains marginal compared to the million airline tickets sold for the event. A Paris-New York round trip emits approximately 2 tonnes of CO₂ per passenger. A few tens of thousands of European supporters erase at once all eco-design efforts.
Qatar had benefited from its compact geography: 8 stadiums within a 55-kilometer radius, accessible by air-conditioned metro. Spectators stayed in a single country and traveled locally. The carbon balance of 3.63 MtCO₂e remained twice higher than Russia 2018, but the logistical footprint stayed contained.
The 2026 edition explodes this logic. The 16 host cities spread from Vancouver to Mexico City, over 4,500 kilometers. A supporter following their national team will easily travel 15,000 kilometers in three weeks. FIFA projects 5.7 million spectators compared to 3.4 million in Qatar, mechanically driving demand for long-haul flights.
The Expanded Format Transforms Carbon Arithmetic
Extending the tournament from 32 to 48 teams produces a multiplier effect across the entire supply chain. 104 matches instead of 64, a 63% increase in additional matches. 16 additional teams with their delegations, technical staff, and supporters. The group stage goes from 48 to 72 matches, stretching the competition over a full month.
This mechanics multiplies travel opportunities. Each group now consists of three teams instead of four, reducing matches per team but increasing qualification uncertainty. Supporters can no longer target two or three cities to follow their national team: they must plan continental routes.
Geographic distribution aggravates the equation. Canada hosts 13 matches, the United States 78, Mexico 13. Semifinals and the final take place in the United States, forcing all finalists to cross at least one border. A scenario that guarantees additional flights for the 40,000 spectators expected in each semifinal stadium.
Greenly’s analysis shows that this variable geometry weighs more heavily than the energy efficiency of infrastructure. New American stadiums incorporate low-carbon technologies: solar panels, water recovery systems, recycled materials. But these improvements represent a few thousand tonnes of avoided emissions against millions generated by aviation.
Compensation Promises Encounter the Scale of the Problem
FIFA committed in 2021 to reduce its emissions by 50% by 2030 and achieve carbon neutrality by 2040. The organization is banking on carbon offsetting, energy efficiency of stadiums, and optimization of local transport to meet its targets.
The 2026 carbon plan provides for purchasing carbon credits to neutralize 100% of tournament emissions. FIFA finances reforestation projects in Central America and renewable energy installations in Mexico. Estimated budget: 180 million dollars over four years, or 23 dollars per tonne of CO₂e offset.
This strategy stumbles on the carbon additivity of the expanded format. Even by halving the footprint per spectator through public transport and clean energy, 5.7 million visitors will emit more than 3.4 million. The volume effect overrides marginal efficiency.
Carbon offsetting itself remains debated. Forest projects financed by FIFA will take 20 to 30 years to sequester the promised CO₂, when 2026 flights will emit instantly. Carbon credit verification mechanisms face recurring criticism regarding their real additivity.
Most importantly, FIFA continues to expand its competitions parallel to its climate commitments. The Club World Cup will expand from 24 to 32 teams in 2025. The 2030 World Cup will take place across three continents: Spain, Portugal, Morocco, with opening matches in Uruguay, Argentina, and Paraguay. A geography even more dispersed than 2026.
The Sports Industry Faces the Wall of Expansion
Professional football illustrates a broader contradiction in entertainment industries. European leagues multiply matches to maximize television revenues. The Champions League expands from 32 to 36 clubs in 2024, adding 64 additional matches. The Premier League is studying a move to 22 teams and the organization of matches in the United States and Asia.
This expansion logic generates threshold effects on carbon footprint. One additional Champions League match mobilizes 3,000 displaced supporters, 100 journalists, 40 delegation members. Multiplied by 64 new matches, the climate impact exceeds that of any technological improvement to stadiums.
Sports organizations are betting on decarbonization of air transport to resolve the equation. Commercial aviation aims for carbon neutrality by 2050 via sustainable fuels and hydrogen. But these technologies will struggle to compensate for traffic growth over the next twenty years, a crucial period for limiting warming to 1.5°C.
A few events are exploring constrained formats. UEFA organized Euro 2020 in 11 European countries to reduce travel, before returning to a single country in 2024. The Paris 2024 Olympic Games prioritized existing venues and rail transport. But these experiments remain marginal against the broader trend.
Television Revenues Against Climate Urgency
World Cup expansion responds to inexorable economic logic. FIFA derives 75% of its revenue from television rights, indexed to the number of matches and participating teams. Moving to 48 teams generates an additional 1 billion dollars over the 2023-2026 cycle, according to the organization’s projections.
This windfall finances global football development. FIFA redistributes 1.6 billion to its 211 member federations over four years, or 7.5 million per federation. World Cup money builds training centers in Bhutan, trains referees in Vanuatu, finances women’s leagues in sub-Saharan Africa.
The equation directly opposes sports development and carbon footprint. Reducing the format to 32 teams would save 4 MtCO₂e but would deprive 16 countries of television exposure valued at 50 million dollars per national team. For Jamaica or Panama, a World Cup qualification represents the equivalent of ten years of federation budget.
Broadcasters push in the opposite direction. ESPN and Fox Sports paid 400 million dollars for American rights to the 2026 World Cup, betting on local enthusiasm to justify the expenditure. NBC Universal and Amazon Prime are competing for European rights from 2030, banking on the continued expansion of formats.
This dynamic locks in the expansion of competitions for the next fifteen years. Television contracts are signed until 2038, including automatic extension clauses for the number of participants. FIFA should announce a move to 40 or 48 teams for the Club World Cup by 2027.
Toward Decarbonized Regional Competitions?
Part of the sports industry is exploring alternatives to the global expansion model. The NBA organizes regional seasons in Europe and Asia to limit intercontinental flights. European rugby tests reduced cup formats for weekends to decrease logistical footprint.
UEFA could replicate this model with regional World Cups preceding a restricted final tournament. 6 continental tournaments of 16 teams each, then an intercontinental final phase of 12 teams in a single country. This geometry would divide international travel by three while preserving the event’s universality.
Technology can also decouple audience from travel. Virtual reality broadcasts enable immersion from home equivalent to physical travel. Meta and FIFA are testing 360° retransmissions for the 2025 Club World Cup, targeting supporters who cannot travel.
But these innovations stumble on the political economy of spectator sports. Sponsors pay for stadium attendance, not virtual audiences. Television atmosphere depends on the sound density of the stands. A half-empty stadium degrades the event’s market value, creating a downward spiral for rights.
The 2026 World Cup tests full-scale this tension between economic expansion and carbon constraint. If the footprint actually reaches 7.8 MtCO₂e, equivalent to a country like Cyprus for one year, FIFA will have to choose between its climate commitments and its growth logic. An equation that the global entertainment industry has yet to resolve.
