1 See following pages for an explanatory key to the tables and graphs below. NOTE: The central axis on the bar graph represents the average score for all countries. Bars to the right of the axis represent above average performance, and bars to the left represent below average performance on that particular indicator. Page 1 of 5

2 2005 Environmental Sustainability Index Summary The 2005 ESI benchmarks the ability of nations to protect the environment over the next several decades. It does so by integrating 76 data sets tracking natural resources endowments, past and present pollution levels, environmental management efforts, and a society s capacity to improve its environmental performance into 21 indicators of environmental sustainability. These indicators permit comparison across five fundamental components of sustainability: Environmental Systems; Environmental Stresses; Human Vulnerability to Environmental Stresses; Societal Capacity to Respond to Environmental Challenges; and Global Stewardship. Units of Measurement Variables: The variables are the fundamental building blocks of the ESI. Units of measurement are specific to each variable. For example, the variable of dissolved oxygen concentrations in water is measured as milligrams dissolved oxygen per liter water, and the variable of deaths from infectious diseases is measured in deaths per 100,000 population. Indicator score: The indicator scores represent the average of the standardized z-scores of the variables that comprise each indicator. Positive numbers represent above average levels of performance and negative scores represent below average performance as compared to the average performance of the complete set of 146 countries included in the ESI. A z-score of +1 or -1 translates as plus or minus one standard deviation from the mean, respectively. Component score*: The component scores are the equally weighted average of the scores of a group of related indicators. ESI score * : The overall ESI score is the equally weighted average of the 21 indicator scores. The peer group ESI score is the same, but only taking into account the peer group country data to create the standardized z-scores. * Both the Index score and the Component scores are presented as standard normal percentiles. These have a theoretically possible range of 0-100; the actual range is determined by the shape of the distribution of scores across all the countries. In all cases higher scores represent higher measures of environmental sustainability. Page 2 of 5

3 ESI overall score, ranking, and data availability are shown in the table: ESI is the overall score based on the 21 indicators of environmental sustainability (out of a theoretical total possible score of 100) Ranking is the overall rank of the country among all 146 countries in the 2005 ESI. Peer group ESI is the average score of those countries from the same economic peer group (see table below). Variable Coverage is the number of variables for which data were available (out of 76 variables) GDP/Capita is the 2000 purchasing power parity (PPP) measurement for the country used to separate the countries into 5 peer groups. Missing variables imputed shows the number of variables with no data for which an imputation was used. Economic peer groups: Quintile groups by average GDP per capita (PPP) Source: World Bank, World Development Indicators, 2004 Scores for the 21 indicators of environmental sustainability are shown in the bar graphs: The bar graph is set up to illustrate comparisons among countries on the 21 indicators of environmental sustainability from which the overall ESI score is calculated. Negative scores (that fall to the left of the axis) are below average A score of zero is the mean score for all 146 countries. The central axis depicts zero for each Complete 2005 ESI report available at: Positive scores (that fall to the right of the axis) are better than average The empty bars show the average scores for the economic peer group. The shaded bars represent the scores of the country. Page 3 of 5

4 Indicators are also aggregated to create five components of environmental sustainability: The Five Components of the 2005 ESI Scores for the 5 components of environmental sustainability are shown in the radar graph: The point at the center of the spider diagram denotes a score of zero for any of the five systems. (The closer to zero on any line, the poorer the country s performance on that component of environmental sustainability) The points on the ends of the lines radiating from the center denote a score of 100 for any of the five systems. (The closer to 100 on any line, the better the country s performance on that component of environmental sustainability) The point and number along the line denotes the country s score on that component. (The score will fall somewhere between 0 and 100) Lines are drawn to connect the country s scores on each component line. The size of the enclosed, shaded area is a measure of its overall performance. The shape of the shaded area in the diagram reflects the particular distribution of scores across the five components. The larger the area, the higher the overall score on the ESI. Tables of country rankings for the ESI can be found on pages 4-5 of the main report, and similar tables for the component and indicator scores can be found in Appendix D.
