In celebration of Earth Day, NHL Green has teamed up with Sterling Planet, the United States' leading retail provider of environmental assets for corporate, utility and government clients, to attempt to mitigate the environmental impact of the 2013 Stanley Cup Playoffs.

For the second consecutive year, using environmental assets from Sterling Planet, the NHL will counterbalance the estimated carbon emissions resulting from arena electricity consumption during all 2013 Playoffs games and team air travel throughout the Playoffs, based on conservative projections of the expected carbon footprint associated with the 2013 Stanley Cup Playoffs.

Accordingly, Sterling Planet will provide the NHL with 12,850 megawatt-hours (MWh) in the form of Green-e® Energy certified renewable energy certificates (RECs) from U.S. wind projects and 1,148 metric tons of verified emission reductions -- also known as carbon offsets -- from projects authenticated by the Verified Carbon Standard or the Climate Action Reserve, independent accounting programs which validate, measure, monitor and ensure the environmental benefit of the carbon offset projects.

"The NHL's commitment to environmental stewardship is extraordinary," said NRDC Senior Scientist Allen Hershkowitz. "The League is financing watershed restoration, recovering food for donations and promoting measurements of energy, water, and waste at all NHL arenas. Through this GHG reduction initiative -- when combined with the impact from last season -- the NHL will avoid more than 38 million pounds of carbon, making it one of the largest global warming pollution offset initiatives by any sports league ever."

The RECs and carbon offsets together will create a benefit of more than 22.5 million pounds (10,214 metric tons) of avoided emissions of carbon dioxide. The environmental benefit compares to taking approximately 2,100 cars off U.S. roads for a year.
