Fifa could even consider a permanent venue for the World Cup, says Diab. "The lowest carbon stadium or the most environmentally friendly stadium is the stadium that is not built." This is especially the case where stadiums are being built in areas that may not be able to find a use for stadiums after the World Cup is over. In Qatar, for example, he says, it"s "open to question" how so many world class stadiums in such a small geographical area will be used after the tournament. "We"ve seen in previous tournaments of these becoming stranded assets, just left to crumble or being underutilised after the World Cup."
