Chicago has been chosen as a finalist to host the 2016 Summer Olympics. As part of its bid, Chicago promised to host the "Greenest Olympics Yet" but the bid has no binding environmental standards. A city resolution is proposed to mandate that the Olympic Village achieve LEED Platinum certification, the highest standard. This would demonstrate the city's commitment to green building and hosting environmentally friendly Olympics. The resolution details that buildings account for a large portion of carbon emissions and energy costs, and green buildings provide health and cost savings through efficiency. The Olympic Village would consist of towers to be converted to condos after the games.
