The Green Bay Packers recently announced "Packers Green Team," a new program focusing on the use of renewable resources and other sustainable practices at Lambeau Field.
On game days, the field will be powered with energy from Wisconsin Public Service's NatureWise renewable energy program, which produces electricity from wind and biogas sources. About 1.2 million kilowatt hours of electricity will be purchased through the season.
The Packers are also encouraging fans to recycle more in the Lambeau Field. Working with Waste Management, additional recycling containers will be placed around the stadium. The team collected around 7 tons of recyclable material per game last season.
Plastic plates and cups currently used at the stadium's suites and restaurants will also be replaced with food-ware made from biodegradable materials.
Other stadiums with green ambitions include the one at University of Minnesota, Gillette Stadium, NY Mets' Citi Field, and AT&T Park in San Francisco.
