Hosting a World event in just one country is already a handful. First and most obvious, at least one stadium is needed. Some countries may already have stadiums with the required characteristics, but some others have to build them from scratch. Let’s skip for the moment the hydric consumption, just thinking about materials transportation and the building process, emissions-free?
Forgetting the stadium, let’s just take a look at the competition. There will be national teams from lots of countries that will have to move around in planes (private, of course). Each of the 48 national teams will play several matches . Again, emissions-free?
And last, the most important thing in football is the fans. They are not staying at home, people would love to go and cheer for their teams . In their case, the flights would probably be commercial, but the question remains, emissions free?
