The Green Sports Alliance is a non-profit organization with a mission to help sports teams, venues and leagues enhance their environmental performance. Alliance members represent 13 sports leagues and over 90 sports venues and teams - a collaboration that is unprecedented.
The Green Sports Alliance brings sports organizations and environmental experts together in an effort to improve the environmental performance of sports facilities and operations.
Since January of 2010, the Alliance has brought together venue operators, sports team executives and environmental scientists to exchange information about better practices and develop cost-competitive and innovative solutions to their environmental challenges. The information gathered from this collaboration is available to Alliance members in order that they gain a better understanding of how sporting events can be performed in an environmentally sensitive manner.
The Green Sports Alliance was conceived and founded by Paul G. Allen’s Vulcan Inc. and the Natural Resources Defense Council. Inaugural members and partners of the Alliance are the Seattle Seahawks, Portland Trail Blazers, Seattle Sounders FC, Seattle Mariners, Seattle Storm, Vancouver Canucks, the Bonneville Environmental Foundation, and Milepost Consulting. Technical assistance and organizational support has been provided by Green Building Services, Lane Powell, Coates Kokes, Green Bear Group, the Institute for Sustainable Solutions, the U.S. Environmental Protection Agency and other partners supporting the mission of the organization.
“The Stadium Managers Association is very excited to hear about the formation of the Green Sports Alliance. Their objective of developing an advanced environmental model for sports facilities aligns with our objective to assist stadium managers in achieving the highest levels of facility operations. The Stadium Managers Association looks forward to working with the Green Sports Alliance on these common objectives of enhancing the efficient and sustainable operations of stadiums.”
