This article presents case studies from three districts implementing green cleaning. In 2008, Missouri passed legislation requiring state education officials to convene a committee of stakeholders with the purpose of developing green cleaning guidelines and specifications for schools. The guide, published by the Department of Elementary and Secondary Education (DESE), is titled "Green Cleaning Guidelines and Specifications for Schools" and was formally adopted by the Missouri State Board of Education in January 2009. In general, the Missouri guidelines provide a comprehensive approach to green cleaning, including recommendations related to the purchase of "environmentally sensitive" cleaning and maintenance products, janitorial paper supplies, and cleaning equipment. In January 2009, the Columbia Public School District's Custodial Services Department officially adopted the Missouri Green Cleaning Guidelines and Specifications for Schools in an effort to facilitate a healthier environment for students, employees, and visitors. In 2005, New York became the first state in the country to pass a law requiring all public and private elementary and secondary schools to purchase and use environmentally sensitive (green) cleaning products for facility maintenance. The East Meadow Union Free School District, one of the largest school systems on Long Island, began working to bring its cleaning program into compliance with the state law. Since beginning its program, the district has stepped into a leadership role, serving as a role model to other districts across the nation that are developing green cleaning programs. When school districts take the lead in driving sustainability, they set an example for the children and communities they serve. This is why Floyd County Schools, a 21-school district based in Rome, Georgia, uses its sustainability initiatives to not only operate more efficiently and sustainably, but also to educate students about the impact building operations have on the environment. This education has proven immensely valuable. For years, the district's landscaping and recycling programs, as well as other sustainability projects, have been successful both in reducing the district's environmental impact and in teaching children how to be environmental stewards in school and at home.
