EcoArenas, LLC is working with architecture firm Castro Mello Arquitetos to build the world's most sustainable soccer stadium. They are aiming to be the first soccer stadium with a LEED Platinum rating. With features such as re-used materials, solar panels, low flush toilets, a wildlife area as part of the grounds, and many more...they're very likely to reach that goal. The stadium is just one project in a much larger initiative McKee started with fellow Brazilian and friend, Vicente de Castro Mello, in 2008. The initiative is called CopaVerde and is a detailed plan to leverage the 2014 World Cup and 2016 Olympics to transform Brazil into one of the greenest economies in the world.
