The Environmental Sustainability Index (ESI) is a measure of overall progress towards environmental sustainability. The index provides a composite profile of national environmental stewardship based on a compilation of indicators derived from underlying datasets. This Web site provides access to the ESI report, underlying data, and associated maps for the Pilot 2000, 2001, 2002 and 2005 versions of the ESI. The documents made available here provide in-depth details on the analytical framework, quantitative methodology, and data sources that underlie each edition of the ESI. Note that because of data and methodological improvements to each subsequent version of the ESI, the country scores cannot be utilized in time-series analysis. We welcome criticisms, suggestions, and comments.
