The core problem is not hard to spot.
That combination matters. Modern World Cups are already enormous logistical exercises, but 2026 appears likely to stretch the model further than ever. Air travel is expected to carry the biggest environmental cost, especially with supporters, sponsors and corporate guests moving repeatedly between distant host cities.
This is where the political pressure sharpens. has moved away from the language of carbon neutrality after criticism around 2022, but it still says it wants to cut emissions sharply by 2030 and reach net zero by 2040. The tension is obvious: football’s biggest event keeps getting larger, while its climate targets become harder to defend.
Using existing stadiums helps. Encouraging public transport helps. Cleaner technology and lower food waste help. But those steps look modest beside the scale of the travel footprint. If the biggest source of emissions is flying, then the tournament format itself becomes part of the debate.
There is an obvious sporting argument for expansion: more nations, more representation, more global reach. But sustainability critics appear to be forcing football into a tougher conversation about whether growth and climate responsibility can keep moving in the same direction.
That debate will only intensify as host-city plans become clearer and 2026 draws closer. The next storyline to watch is not just who qualifies, but whether can show that its environmental promises still mean something when the world arrives across North America.
