2026 World Cup Projected as Most Polluting Tournament in History

The 2026 FIFA World Cup is projected to be the most polluting tournament in sports history, emitting more than nine million tonnes of CO₂ ^[1].

The environmental impact of the event highlights a growing conflict between the expansion of global sporting spectacles and international climate goals. As FIFA increases the scale of its flagship tournament, the carbon cost of logistics and infrastructure risks undermining the organization's public sustainability pledges.

The tournament will be hosted across the U.S., Canada, and Mexico [2, 3]. This expansive geographical footprint contributes to a massive carbon footprint due to the necessity of extensive air travel for teams, officials, and millions of fans [3, 4].

Further contributing to the ecological damage is the record 48-team format ^[4]. The increase in participating nations necessitates more flights and longer stays, while the construction of large stadiums to accommodate the larger crowds generates significant emissions ^[4].

These projections contrast with previous assertions from FIFA and its president, Gianni Infantino, regarding the tournament's environmental standards [1, 5]. Critics said the scale of the event makes it an ecological disaster, regardless of specific mitigation efforts implemented by the host nations [1, 3].

FIFA has not yet provided a detailed counter-analysis to these specific emission projections, but the sheer scale of the 2026 event — spanning three countries — represents a departure from more concentrated tournament models used in the past [2, 3].
