Two days ago MetLife stadium in New Jersey was the home to the most-watched television event in the world: the Super Bowl. Over 111 million people tuned in to watch what turned out to be a lopsided game, with the Seattle Seahawks easily trouncing the Denver Broncos in a 43-8 victory. But what has not been covered much in the media is the stadium itself, which many energy efficiency advocates see as a champion in its own right. Built to replace the older Giants Stadium and opened in 2010, MetLife has since become one of the most efficient sports complexes in the United States.

Since opening its doors nearly four years ago, MetLife has saved nearly $20 million in operating expenses while reducing its carbon emissions by over 230,000 metric tons, compared to the old stadium. These savings were planned from the very beginning, with the owners of the stadium agreeing to environmental efforts in 2009 that would go on to make MetLife a very green building.

While it was being built, MetLife ownership worked with the Environmental Protection Agency (EPA) on finding materials to build with. They agreed to use 40,000 tons of recycled steel to construct the space itself, as well as environmentally-friendly concrete and seats that were made from reused steel and plastic. The work with the EPA did not end there, as every six months officials from MetLife send a report highlighting their continued efforts – including the use of solar power and stadium-wide recycling efforts, to cut down on the amount of waste produced.
