Walden III became Racine's first Green School in November 2006. The Walden Green School Initiative is an organization at the school which encourages environmentally-friendly actions, such as students recycling cans, bottles and paper, and plans for future efforts for more environmentally-conscious progress, funded by charitable donations and philanthropic grants. The group was instrumental in the installation of solar panels on the school's roof in 2008, which have raised money for other energy-efficiency projects, such as the installation of new weather-resistant doors in the school's breezeway
