2014 EPI Data Files

This spreadsheet contains the 2014 EPI Framework and Indicator scores. It does not include the 2002-2012 Backcasted Scores or Raw Data. 

This spreadsheet contains the 2014 EPI indicator scores and backcasted data from 2002-2012. Included is a 'Data Dictionary' Spreadsheet that explains the variable name codes used for the Objectives, Policy Issues, and Indicators. Note: this spreadsheet does not contain the raw data values used to construct indicators. For the raw data, please download the individual raw data file for the relevant policy issue category.

A single spreadsheet that contains the detailed statistical weightings applied to each level of aggregation (e.g., indicator, issue, and objective) to calculate the 2014 EPI.

This spreadsheet contains detailed scoring information on whether countries allow, restrict, or ban the Dirty Dozen Persistent Organic Pollutants (POPs) through the Stockholm Convention.

Abstract: The number and type of indicators used for assessing environmental sustainability around the world have proliferated dramatically within the last few years. From a count of nearly zero just two decades ago, environmental indexes now number in the hundreds. While much has been published on the technical aspects of indicator construction, much less attention has been given to the actual management and policy uses of environmental indicators. Whether environmental indicators are performing a true service in the policy arena is still an open question. This paper addresses this gap by reviewing the impacts of indicators in policy and management contexts generally and in the environmental policy context specifically. We examine the theoretical role that indicators may play in informing or driving policy decisions (e.g., by simplifying choices, highlighting trends, or holding decision makers accountable) and examine case studies of indicator uses around the world derived from a survey of indicator efforts, to identify factors that affect how indicators are used. Where possible we identify best practices for designing effective indicators that can drive policy decisions.

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.
