Target Field, the new home of the Minnesota Twins baseball team, earned the U.S. Green Building Council's (USGBC) Leadership in Energy and Environmental Design for New Construction (LEED-NC) Silver Certification. With a total of 36 points, it also has been designated America's greenest ballpark.

To keep the facility sustainable, St. Paul-based Marsden Bldg Maintenance employs an aggressive green cleaning program. From green chemicals to composting paper towels, the building service contractor strives to be as green as possible.
