As the newly-named host of the 2034 World Cup in men's soccer, Saudi Arabia says it will construct or renovate 15 stadiums, create a futuristic city and expand airports in a massive buildout to accommodate millions of athletes, coaches and spectators.
That will emit tons of planet-warming greenhouse gases as concrete and steel are manufactured and transported, diesel-powered excavators and trucks are used and new buildings are powered and cooled. When all the emissions associated with the world's buildings are grouped together, they are the largest contributor to climate change.
