With games spread across the United States, Mexico, and Canada, the 2026 World Cup is expected to increase flights, travel, and energy consumption, raising an alert about extreme heat, logistics, and unprecedented climate impact.
The 2026 World Cup could go down in history for a reason that is nothing to celebrate: the forecast is that the tournament will exceed 9 million tons of carbon dioxide, according to ecoticias.com. If the estimate is confirmed, the event will be pointed out as the most polluting ever held in sports.
The alert gains strength because the competition will take place in three countries at the same time, with venues spread across the United States, Mexico, and Canada. In practice, this increases the pressure on airplanes, ground transportation, accommodation, energy, and all the infrastructure needed to keep a tournament of this size running for over a month.
Besides the climate footprint, the World Cup is also expected to face another major problem: extreme heat in the North American summer. For players, fans, and operational teams, the challenge will not only be watching the games but enduring the conditions imposed by a larger, longer, and much more spread out championship than previous editions.

A giant tournament, with 48 teams and 104 games
The 2026 edition will be the largest World Cup in history in terms of participants and matches. There will be 48 teams and 104 games, with matches distributed in 16 cities across three different countries.
This format increases the scale of the event but also multiplies logistical demands. More teams mean more travel, more infrastructure needs, more energy consumption, and more demand for services related to broadcasting, security, telecommunications, and accommodation.
The tournament will be held from June 11 to July 19, 2026, a period when summer usually puts even more pressure on operations in several host cities.
Flights are one of the most critical points of the account
Among the factors that weigh most in the emissions estimate is air transport. The movement of teams, staff, sponsors, and millions of fans between very distant cities tends to push the carbon footprint up.
The host cities are spread across three countries, and some of the distances are extreme. Between Vancouver and Miami, the two furthest points of the tournament, there are about 5,600 kilometers.
The mentioned report also calculates that emissions related to flights may increase between 160% and 325% compared to previous World Cup editions. This difference helps explain why the 2026 World Cup is already surrounded by environmental criticism.
Extreme heat and risk for athletes, fans, and stadiums
The climate issue is not only about emissions. Several studies cited by the publication indicate that various host cities may experience potentially dangerous thermal stress episodes during the competition.
Miami, Dallas, Houston, and Monterrey are among the cities with the highest risk, precisely because of the temperatures expected for the summer. This reignites the discussion about game schedules, the need for longer breaks, and even changes in the calendar of major sporting events.
For experts, the scenario shows that global warming is already beginning to reshape how international championships are organized. And the 2026 World Cup should serve as a tough test for this new limit.
Artificial intelligence enters the field, but does not solve the environmental pressure
While the tournament raises environmental alerts, FIFA also intends to use the edition as a technological showcase. The organization announced AI-based tools for referees, teams, and fans, while the host countries are expected to adopt advanced systems for security and infrastructure management.
This hyperconnectivity will increase the energy and technological dependency of stadiums, digital networks, and broadcast platforms. In other words: the World Cup will also be a test of endurance for energy, connectivity, and large-scale operation.
Any failure in these systems can create a domino effect on essential event services. Therefore, backup networks, stable energy, and quick response gain even more weight in a championship that is already born under pressure.
In the end, the 2026 World Cup promises to be a double milestone: on one side, a showcase of expansion, technology, and new sports structure; on the other, a symbol of the environmental contradictions of modern mega-events. If the forecast of more than 9 million tons of CO₂ is confirmed, the tournament will enter the global debate not only for football but for the climate cost it carries along.
