Environmental Sustainability Index

Project Description
The Environmental Sustainability Index (ESI) is a measure of
overall progress towards environmental sustainability, developed
for 142 countries. The ESI scores are based upon a set of 20 core
"indicators," each of which combines two to eight variables for a
total of 68 underlying variables. The ESI permits cross-national
comparisons of environmental progress in a systematic and
quantitative fashion. It represents a first step towards a more
analytically driven approach to environmental decisionmaking.

The documents made available here provide in-depth details on the
analytical framework, quantitative methodology, and data sources
that underlie the ESI . We welcome criticisms, suggestions, and

The ESI is the result of collaboration among the World Economic
Forum's Global Leaders for Tomorrow Environment Task Force, The
Yale Center for Environmental Law and Policy, and the Columbia
University Center for International Earth Science Information
Network (CIESIN).
