AEG is a major player in the arena industry: Besides owning Los Angeles's Staples Center, the firm manages Kansas City's Sprint Center, Portland's Rose Garden, and Minneapolis's Target Center, among others. So when the firm says it wants to be a leader in green arenas, others will listen. Indeed, the stated goal from AEG is pretty strong: "to be the leaders in our sector, the sports and live entertainment industries, by establishing the environmental standards by which other such organizations can measure themselves. To accomplish this, we are attempting to detail, measure and manage all aspects of our environmental performance."

Now, declaring they want to be a leader is a pretty ambitious statement, as there are more than a few arenas with a strong environmental record: St. Paul's Xcel Energy Center continues to wrack up the awards and recognition from its continued commitment to green management. And Consol Energy Center, the new home of the Pittsburgh Penguins (NHL), is now LEED-certified.

Still, strip aside the rhetoric and you have something pretty cool from AEG. The firm certainly has implement green practices: there's solar on the Staples Center roof, installing a green roof at Target Center, and going for LEED certification at the Rose Garden. The goals are attainable: by 2020 the firm wants to achieve a 25 reduction in solid waste sent to the landfill, 20 percent reduction in greenhouse gas emissions, a 20 percent reduction in water use, 15 percent of all electricity from solar power.
