The Chicago Blackhawks will wear one-of-a-kind green St. Patrick's Day warm-up jerseys on Sunday, March 12, before hosting the Minnesota Wild at the United Center at 11:30 a.m.

Each autographed warm-up jersey will be auctioned off online. All jerseys will be auctioned off to fans on auctions.nhl.com from Sunday, March 12, through Friday, March 24, with all proceeds benefitting Chicago Blackhawks Charities. Select green apparel will be available for purchase at the Blackhawks Store located by section 117, in addition to the Michigan Avenue and Oakbrook store locations.

In conjunction with the National Hockey League's Green Week, the Blackhawks will host a hockey/sport equipment collection in-arena at section 113 on Sunday, March 12, and during the 2017 Illinois State High School Hockey Championships on Friday, March 17. Fans are encouraged to bring their used equipment to either game for donation. In-game presentation during Sunday's contest will feature various videos on how to maintain environmentally friendly practices and a public service announcement by Jonathan Toews.

The Blackhawks have also been a member of the Green Sports Alliance, a nonprofit organization that leverages the cultural and market influence of sports to promote healthy, sustainable communities, since 2015. In a continued effort to promote sustainable business practices, the National Hockey League, its member Clubs, and League partners will celebrate NHL Green Week from March 11-17, 2017. The NHL and its Member Clubs are committed to improving hockey's environmental impact. Hockey can trace its roots to the frozen freshwater lakes and ponds of North America and Europe. The ability to skate and play the game outdoors is a critical component of the NHL's history and culture. Major environmental challenges such as climate change and freshwater scarcity affect future opportunities for hockey players of all ages to take the game outside. Since its launch in 2010, NHL Green has been committed to preserving the environment - including the frozen ponds that inspired and cultivated the game more than 100 years ago.

Through the organization's partnership with Constellation, the Blackhawks will also host "Go Green Night" at the United Center on Friday, March 31, when the team faces off against the Columbus Blue Jackets at 7:30 p.m. in support of the organization's commitment to environmental sustainability. Constellation will supply Green-e Energy Certified Renewable Energy Certificates (RECs) to match the electricity use during the game with energy generated from environmentally responsible renewable resources minimizing the carbon footprint of the game. Green-e Energy certifies that renewable energy certificates meet the minimum environmental and consumer protection standards established by the non-profit Center for Resource Solutions. For more information on Green-e Energy certification requirements, please visit www.green-e.org.
