For billions of fans, the World Cup is the ultimate celebration of sport. But for communities living near tournament venues—and for the planet as a whole—the carbon footprint of football’s flagship event is increasingly impossible to ignore. As FIFA President Gianni Infantino pushes forward with plans for an expanded 48-team tournament in 2026, co-hosted by the United States, Canada, and Mexico, a growing chorus of scientists and activists is demanding accountability.
The numbers are staggering. A 2022 study by the Carbon Market Watch estimated that the Qatar World Cup generated roughly 3.6 million tonnes of CO2—more than double FIFA’s initial claim. Now, with a larger format and a sprawling three-nation footprint, 2026 could dwarf that figure. Dr. Laurie Laybourn, climate researcher at the University of Oxford, warns: “If FIFA continues to rely on voluntary offsetting without binding emission reductions, the World Cup will become a symbol of greenwashing rather than global unity.”
The Carbon Legacy of Football’s Biggest Stage
International air travel accounts for the lion’s share of World Cup emissions. In 2026, teams and fans will criss-cross a continent, flying between 16 host cities—from Seattle to Toronto, Los Angeles to Miami. A single transatlantic round trip from London to New York emits about 1.4 tonnes of CO2 per passenger. With projected attendance of over 5 million spectators, the aviation footprint alone could exceed 6 million tonnes.
FIFA has pledged to make the 2026 tournament “carbon neutral” through offsets, such as reforestation projects. But critics argue that offsetting is a flawed accounting trick. A 2021 review in Nature Climate Change found that many carbon offset programs fail to deliver the promised emission reductions. Moreover, the construction of new stadiums—the 2026 tournament will use 11 existing venues and five that require major renovations—adds significant embodied carbon. Stadiums in Mexico City and Guadalajara will need upgrades that involve concrete and steel, materials responsible for roughly 10% of global emissions.
“We are kidding ourselves if we think planting trees can compensate for the fossil fuels burned by thousands of flights,” says Dr. Elena Franco, an ecologist at the University of British Columbia who studies the environmental impact of mega-events. “FIFA should be investing in direct emission reductions, not just offsets.”
The Promise and the Performance Gap
In 2021, FIFA published its Climate Strategy, pledging to reduce emissions by 50% by 2030 and reach net zero by 2040. The plan includes carbon budgets for events, renewable energy use in stadiums, and incentives for sustainable travel. Yet, a review by the climate watchdog Carbon Tracker in 2023 found that FIFA had not disclosed a concrete roadmap for meeting those targets in the 2026 cycle.
Infantino, who has been FIFA president since 2016, has often focused on financial growth. Under his leadership, FIFA’s revenue reached a record $7.6 billion in the 2019–2022 cycle, driven largely by World Cup broadcasting rights and sponsorships. But a 2022 report by the nonprofit Transparency International noted that FIFA’s sustainability commitments lacked independent verification. “Without third-party audits, these pledges remain aspirational at best,” the report concluded.
The discrepancy is particularly glaring in the global south, where many of the stadiums for the 2026 tournament are located. Host cities like Mexico City face water scarcity and air pollution challenges. A 2019 study by researchers at the National Autonomous University of Mexico found that the construction of the Estadio Azteca’s renovations could increase local particulate matter by 12% during construction phases. For residents living near the site, that means higher rates of asthma and other respiratory illnesses.
Biodiversity and Stadium Construction: An Overlooked Crisis
Beyond carbon emissions, the expansion of World Cup infrastructure threatens local ecosystems. In Vancouver, one of the proposed 2026 host cities, the planned upgrades to BC Place Stadium involve expanding parking lots and building new access roads—paving over green corridors used by migratory birds. Dr. James Thornton, an ecologist from the University of Washington, notes: “The Pacific Flyway is an essential migratory route. Habitat fragmentation from tournament-related construction could harm bird populations already stressed by climate change.”
The situation is similar in Toronto, where the renovation of BMO Field may encroach on the Lake Ontario shoreline, a vital habitat for fish and waterfowl. A 2020 assessment by the Toronto and Region Conservation Authority warned that construction runoff could increase sediment in the lake, damaging spawning beds for native species like lake trout.
FIFA’s own Sustainability Strategy acknowledges the importance of “protecting biodiversity,” but it does not mandate specific pre-construction environmental impact assessments for host city upgrades. Instead, the responsibility falls on local organizing committees—a patchwork approach that experts say can lead to inconsistent enforcement. “We need a binding minimum standard for all host nations,” argues Dr. Thornton. “Not just a checkbox on a sustainability brochure.”
What the 2026 World Cup Means for Climate-Vulnerable Nations
For low-lying island nations and developing countries that contribute little to global emissions but suffer the most from climate impacts, the World Cup’s carbon footprint sends a damaging signal. Dr. Marisol Fernandez, a climate policy expert at the University of the West Indies, explains: “When a mega-event like the World Cup claims carbon neutrality through offsets while expanding its travel footprint, it normalizes the idea that adaptation and compensation are sufficient, rather than pushing for deep decarbonisation.”
The 2026 tournament will be the first in history to feature 48 teams, and FIFA has already announced that the 2030 edition will span six countries across three continents. For Infantino, this expansion is a business opportunity—more matches mean more broadcast revenue. But each additional host nation adds layers of travel, construction, and waste.
In response to mounting pressure, FIFA has launched a “Football for the Planet” initiative partnering with the United Nations Framework Convention on Climate Change. But details remain sparse. A spokesperson told QuasarPost that the 2026 Local Organising Committee would release a full sustainability report by mid-2025. Until then, many scientists remain skeptical.
Dr. Laybourn sums up the challenge: “FIFA has an enormous platform. If President Infantino genuinely wants to leave a legacy, he should champion a binding emissions cap for each tournament and invest in climate adaptation for host communities. Otherwise, the World Cup will become a symbol of the disconnect between sporting rhetoric and planetary reality.”
As the countdown to 2026 begins, fans and activists alike are watching not just the scoreboard, but the carbon meter. The next three years will determine whether FIFA’s climate promises are a goal scored or one conceded.
