"We try to use the iconic statue of baseball to communicate to fans," said Allen Hershkowitz, senior scientist at the Natural Resources Defense Council. "Americans love sports, and if we can get them to hear the environmental message when they go to sporting events, that's helpful.
"Most sports are played outdoors. Most baseball games are played outdoors. Global warming is not good for sports. Storms, droughts, floods, they aren't good for baseball."
The electricity used at Busch Stadium during the All-Star events is being offset by wind-energy certificates purchased. An estimated 287 metric tons -- or 633,312 pounds -- of carbon dioxide emissions will be saved from entering the earth's atmosphere because of MLB's decision to purchase the green power.
"If there's one thing we can say about baseball, it's not political," Hershkowitz said. "So to have Bud Selig, the commissioner of baseball, say, 'Global warming matters to us, and we want to figure out how to reduce our ecological footprint,' that takes the politics out of the debate about global warming."
In addition, MLB Green Teams are present at all All-Star events to collect as many plastic bottles of beer, soda and water as possible. MLB and the St. Louis Cardinals hope to recycle 20 tons of plastic, cardboard and paper generated during the three days of All-Star events, or about 25 percent of the total trash generated.
"The All-Star Game celebration is a celebration of all of our values," said John McHale, executive vice president, administration and chief information officer for Major League Baseball. "As [Commissioner Bud Selig] never stops reminding us, we are a social institution with social obligations. We mostly play the game outside and are tied to the grass and the air and the water, so staying ability is a very important value for us to embrace.
"We play on the earth. That's where our game takes place, so all of those kinds of things are important to us. "
