Environmentally preferable products, sustainability, "green," reducing environmental footprint--have all become part of the everyday lexicon as schools, businesses, households, and the public sector have increasingly focused on strategies and tactics designed to reduce their impact on the environment and human health. State governments have been leaders in this area by adopting policies and implementing programs intended to improve their environmental profile and otherwise enhance their sustainability objectives. A key tactic in greening state government is the adoption of procurement policies that promote the purchase and use of products and services that have a reduced negative impact on the environment and human health when compared to their traditional counterparts. Ten states plus the District of Columbia now require or encourage schools to adopt green cleaning programs, and that number will continue to grow as information about such policies and programs becomes more readily available and other states emulate those that have gone before them. This article provides a summary of the various approaches taken by states and provides more detail about this positive trend. (Contains 1 footnote.)
