Providing safe and healthy learning environments for our children is a fundamental way to advance sustainability in our K-12 schools. However, according to reports by the Government Accountability Office, the U.S. Department of Education, the American Federation of Teachers and other organizations, many schools are in poor condition, and many have environmental health issues (GAO 1995) (GAO 1996) (DoEd 1999) (AFT 2008). Research shows that a school's physical environment impacts the health, performance, and productivity of both the students and the staff. Healthy, efficient school environments embrace sustainable practices that promote good health, generate additional funding for schools, improve academic performance, and evoke a spirit of environmental stewardship and accountability amongst students and staff. By encouraging the adoption of school environmental health programs and innovative green practices, the nation will reap long-term benefits from healthy, high-performing schools.
