You may have thought the greenest thing about Philadelphia's major league baseball team was its furry green mascot, the Phillie Phanatic. But the city that once led the nation as its first capital back in 1774, is leading the U.S. in a new way in 2008: its professional sports teams have taken unprecedented steps towards greening their enterprises. In April 2008, the Philadelphia Phillies announced it would offset the carbon footprint created by electricity use at Citizens Bank Park. It bought 20 million kilowatt-hours of Green-e Certified Renewable Energy Certificates, which the U.S. Environmental Protection Agency says represents the largest single purchase of 100-percent renewable energy in professional sports.
