One of the buildings, the Arena Fonta Nova, is applying for LEED certification and will host several games during the World Cup. It was modeled using 30% less steel and features a light-weight metal roof that allows for maximum ventilation to keep the arena cool as well as a water collection system and recycling installations to reduce waste.
It is the goal of FIFA and Brazil to create a sustainable event with advances in waste management, the promotion of recycling, and the use of green buildings. They will strive to minimize the carbon footprint that the World Cup will leave behind, and 2014 may become an extremely important year for green building and design.
