According to the USA Today (McLean, Virginia), Major League Baseball is partnering with the Natural Resources Defense Council (both of New York) to increase each team's green programs, from increasing recycling to installing solar panels or, perhaps, wind turbines at some of the league's 31 ballparks.
The Team Greening Program will provide each team advice on all aspects of the team's operation, including concessions and transportation. The program will not be a blanket mandate, as each team has different needs — the Seattle Mariners, for example, began composting Safeco Field's food scraps last year, diverting 100 tons of material from landfill and saving the team on disposal costs.
Some cities are announcing greening schemes ahead of the Team Greening Program. The New York Mets, in partnership with the U.S. Environmental Protection Agency (Washington), recently announced environmental goals for its new stadium, Citi Field, while the Pittsburgh Pirates launched its "Let's Go Bucs, Let's Go Green" program this past Tuesday.
One of the NRDC's blogs even recently offered tips for greening one's fantasy baseball team.
