Good news for the Minnesota Twins and Minnesota residents: Target Field, is the first sports facility to be LEED-certified both for new construction and the operation and maintenance of the ballpark.

The Milwaukee Brewers will highlight the environmentally advanced features of Miller Park and how the ballpark is run during the team's inaugural "Green Week" from June 20-26, as the Brewers will launch their "Brewing a Greener Game" sustainability initiative.

NHL Green, the National Hockey League’s sustainability initiative, will oversee the NHL Water Restoration Project, an first-ever attempt to balance the League’s water footprint, with the goal of making the 2011 Stanley Cup Final the first ever water-neutral series in League history.

Another improvement to Chase Field as the Arizona Diamondbacks prepare for a big season: an addition that will generate 75 kilowatts of solar power and also provide needed shade for fans as they enter and exit the ballpark.
