Saudi Arabia, the host of the 2034 World Cup in men’s soccer, plans to construct or renovate 15 stadiums, create a futuristic city, and expand airports to accommodate the event, resulting in significant greenhouse gas emissions. Critics argue that hosting the World Cup in countries with developed soccer culture and industry would be more sustainable. Saudi Arabia's bid includes sustainability initiatives, but the scale of the event could make it the most carbon-intensive World Cup in history. Despite concerns about environmental impact, FIFA accepted Saudi Arabia's promises regarding sustainability and climate measures.
