Abstract: This manual serves as a guide to the process of developing an environmental performance index based on the experience of the Yale Center for Environmental Law and Policy (YCELP) and the Center for International Earth Science Information Network (CIESIN) at Columbia University in developing the Environmental Sustainability Index (ESI) and its subsequent form, the Environmental Performance Index (EPI). Here we share our “lessons learned” in creating performance indices, particularly with respect to environmental issues.
