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.
The 2014 EPI takes into account whether an issue is material, that is relevant, for each country. For example, a country that lacks a coastline does not receive a score for Fisheries. The goal of materiality is to level the playing field between countries so that they can be more consistently compared to one another. Because countries have different natural resources, topographies, and geographies, the EPI tries to take these considerations into account.
This spreadsheet details the materiality filters used as well as the population, land area and income group of each country.

A comparison of EDI and EPI scores, surprisingly, does not show any meaningful relationship between environmental performance and access to environmental rights, although the same size of countries (70) could be partly responsible for the weak correlation.

From giants like China to upstarts like the Basque Country, the group of states and regions taking our cue is always growing.Though the influence of the EPI can be measured in many ways, one of the ways we know we’re having an impact is the extent to which countries and even sub-national actors have taken up our methods and language.

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.
