The Green Sports Alliance is a non-profit organization with a mission to help sports teams, venues and leagues enhance their environmental performance. The founding members of the Alliance are from six different professional sports leagues—a collaboration that is unprecedented.
The founding Alliance members include the Vancouver Canucks (NHL), the Seattle Storm (WNBA), the Seattle Mariners (MLB), the Seattle Seahawks (NFL), the Portland Trail Blazers (NBA) and the Seattle Sounders FC (MLS). The founding partners of the Alliance are the Natural Resources Defense Council, Bonneville Environmental Foundation, United States Environmental Protection Agency, Portland State Institute for Sustainable Solutions, Green Building Services, Coates Kokes, Green Bear Group, Lane Powell and Milepost Consulting.
Since January of 2010, venue operators, sports marketing directors and environmental scientists have collaborated through the Alliance to exchange their real world experiences and create metrics that are meaningful and measurable. The information gathered from this collaboration is now available to members and partners not only to gain a better understanding of the impact sporting events have on the environment, but also to provide inspiration and a roadmap for teams and venues to make changes to reduce that impact.
Since the North American launch in March 2011, more than 50 sports teams and venues from across North America have joined the Green Sports Alliance, representing nine professional sports leagues.
