This checklist offers tips and resources to help schools identify opportunities to "green" their buildings and operations, focusing on common-sense improvements that schools can make in their daily operations to minimize or stop potential health and environmental problems before they start. The first section discusses the benefits of a green school program. The second section highlights management strategies. The list of environmental strategies includes: energy use; solid waste generation; indoor air quality; hazardous materials; mercury use; pest management; mold growth; water consumption; laboratory waste; building construction/renovation; purchasing; groundskeeping; and food service. Each section presents a list of strategies, a "Did you know?" box, and referrals for obtaining further information. (SM)
