In recent years, concerns over environmental degradation and environmental sustainability have pushed governments to search for new ways to combat environmental problems. One such approach, which is gaining in popularity, is environmentally preferable purchasing (EPP). EPP attempts to address environmental challenges by taking advantage of government's vast purchasing power to create strong markets for environmentally friendly products and services. This article reviews governments' experience with EPP in the United States. Specifically, the article describes the development of EPP in the federal government and reviews EPP activities at both the national and subnational levels. Next, the article presents several broad strategies that governments and procurement professionals can pursue in implementing EPP. The article concludes by identifying several challenges facing EPP.
