The very next year, the greatest show on Earth was about to begin: the FIFA World Cup. His country had not qualified. His city did not even have a proper football pitch. But in 2002, when South Korea and Japan co-hosted the tournament, the first World Cup ever held in Asia, his father sat him in front of a television screen and showed him something he had never seen before: the whole world playing one game.

That year, Brazil won the cup. He was one year old. He understood nothing. But maybe, somewhere beyond understanding, he felt something.

By 2006, he was kicking a plastic bottle around a dirt road in front of a tea stall while there was a debate going on about Messi or Ronaldo going to be the next big thing. By 2010, football became a ritual. Late nights. A small screen. His father was sitting beside him. They laughed. They cheered. They believed. Then came the final. Iniesta scored in extra time. Spain won. And he cried without knowing why. By 2022, he was twenty-one, educated, aware, watching a game on his phone at University Hall while reading about migrant worker deaths in another tab. And now in 2026, he is twenty-four. He still loves football. He always will.

But the planet he was born on has warmed up by over 1.2°C since his birth. The Arctic has lost a third of its summer ice. His own country floods harder every monsoon season. And this summer, the biggest World Cup in history, 48 teams, 3 countries, 16 cities, 104 matches, is projected to generate up to 491,340 tonnes CO₂e equivalent. That is around 184% higher than Qatar 2022, 58% higher than Russia 2018, 69% higher than Brazil 2014, 95% higher than South Africa 2010, 420% higher than Germany 2006, and 130% higher than South Korea & Japan 2002.

His love for the game grew. The emissions grew faster

Moving from 32 to 48 teams is not simply adding sixteen more squads to a spreadsheet. It is an increase in everything that moves. According to Alexis Normand, co-founder of carbon accounting platform Greenly: “The bigger an event, the more people attend, the more that fly to the different venues, the higher it emits. That’s the reason the U.S., Mexico, and Canadian World Cup is going to be basically a record setter, because it’ll have nearly three times more spectators than the previous World Cup, and they’re going to be travelling across much larger distances.”

But the expansion creates a second-order problem that is easy to miss. A larger format does not just add travel; it also makes travel harder to optimise. More teams mean more constraints in scheduling, rest periods, broadcast windows, and group-stage logistics. The system becomes less efficient the bigger it gets. A 48-team World Cup does not just raise emissions arithmetically. It reduces the tournament’s own capacity to keep those emissions in check.

This is what makes 2026 different from simply “a bigger Brazil 2014.” The two variables, scale and geography, are interacting with each other, not sitting side by side. And when they interact, emissions do not rise linearly. They multiply.

What Qatar teaches us (If we are willing to learn)

Qatar 2022 (from a sustainability perspective, not human rights perspective) is important precisely because it shows what happens when a large global event is hosted in a geographically compact form. The tournament still involved substantial international travel, but once teams and travelling groups arrived, the domestic travel burden remained extremely low.

The compact nature of Qatar 2022 eliminated the carbon footprint of domestic air travel that fans, players, and officials were required to do to attend matches in previous World Cups.

What Qatar separates, that most discussions blur, is the difference between global accessibility and internal mobility. A World Cup will always carry large international travel emissions. Fans fly from Buenos Aires, Seoul, Lagos, and Dhaka. That is structural. That is the nature of a global tournament. But what happens after people arrive, and how far they move within the host system, is a design decision. And Qatar made that decision well, even if it made other decisions badly.

This is why Qatar 2022 sits well below Brazil 2014 in the workbook, despite both being 32-team editions. Brazil 2014 reached 290,847 tonnes CO₂e, while Qatar 2022 is estimated at 173,212 tonnes CO₂e. The difference is not merely about tournament era or popularity. It is about geography.

According to the Greenly report, 87% of the 2026 tournament’s total emissions will come from spectator travel, generating an estimated 6.82 million tonnes of CO₂e. The internal movement within North America is a major portion of that. In many discussions about sport and climate, international aviation naturally receives the most attention. And in the 2026 projection, international travel is indeed the largest component at 331,433 tonnes CO₂e, or 67.5% of the total. That does not make domestic movement negligible.

In the same projected case, domestic travel contributes 159,907 tonnes CO₂e, or 32.5% of the total footprint (although this is likely the weakest part of the model, as it uses rather simplistic assumptions). Still, that is an extraordinary figure. It means domestic travel alone in the projected 2026 tournament is far greater than the entire footprint of England 1966. It also shows that once host geography becomes large enough, internal movement stops being a background issue and becomes a major emissions category in its own right. This is where compactness becomes a sustainability variable.

The blind spot nobody wants to name

The New Weather Institute’s report argues that the real problem is structural: a competition model that is ever larger, more global, and more dependent on long-distance travel. This is compounded by the lack of sustainable alternatives; unlike Europe or Asia, North America does not have extensive high-speed rail networks that would help cut the carbon footprint of transport.

That last point deserves its own moment. Rail is the single most effective domestic alternative to aviation for distances under 800 kilometres. Europe uses it constantly for tournament logistics. But across the 4,500-kilometre spread of the 2026 host cities, rail is either unavailable, impractical, or simply absent. So planes become the default. And when planes become the default across sixteen cities and forty-eight teams, domestic travel stops being a footnote. It becomes a carbon category of its own.

The report also questions FIFA’s climate strategy, accusing the body of having a “blind spot” when it comes to the environmental crisis, pointing to a clear gap between the organisation’s sustainability pledges and the reality of its decisions, such as expanding the tournament or choosing widely scattered host cities.

FIFA acknowledges that air travel is a significant contributor to the overall footprint of any major event, noting that “it is clear that reducing emissions linked to flights is one of the biggest sustainability challenges major event organisers face.” Yet the 2026 sustainability strategy, by multiple accounts, sets no carbon target for the tournament itself. You cannot acknowledge the problem in one sentence and expand it with the next decision.

Sustainability is a design problem, not a branding problem

The most important thing the 2026 World Cup reveals has nothing to do with recycling bins in stadiums, electric team buses, or solar panels on venue roofs. Those matter. But they are downstream interventions applied to an upstream problem that was already locked in the moment host cities were selected.

According to Good Vision’s analysis: “You cannot continue expanding tournaments, increasing air travel, and adding more host cities while simultaneously claiming a commitment to climate goals. At some point, the numbers must be confronted.”

The workbook’s underlying message is not simply that a 48-team tournament emits more than a 32-team tournament. It is that a 48-team tournament across a dispersed tri-national geography creates a multiplier effect. Expansion raises the baseline, but geography determines how severe that rise becomes. In other words, sustainability is not only about what technologies are added later. It is also about what structural decisions are made first.

Venue selection, tournament format, host spread, and transport architecture determine most of a tournament’s emissions before any sustainability team writes a single strategy document. By the time the green branding begins, the carbon geometry is already fixed. A badly designed travel footprint cannot be solved by better messaging.

This is the real lesson. Not that bigger tournaments have bigger carbon costs, that is obvious. The lesson is that dispersed tournaments emit disproportionately more than compact ones. The interaction between scale and geography creates a multiplier, not a sum. And that future mega-event planning, whether it is football, the Olympics, or any global gathering, must treat geography as an emissions decision, not a backdrop.

Back to the boy

That twenty-four-year-old will watch the FIFA World Cup 2026. He will stay up late. He will feel things that words cannot fully explain. Football does that. It always has. It earns its place in the world. But he is also the generation that will live with what this tournament leaves behind, not in memory, but in atmosphere. And he deserves a governing body that takes that as seriously as it takes broadcast rights. The 2026 World Cup may be the greatest in history. It may also be a turning point, the clearest proof yet that in environmental terms, bigger is not just bigger. It is farther. And farther, in 2026, costs the earth.
