PDF file providing overview of data used for 2006 Environmental Performance Index, including raw values for included countries and brief descriptions of how data were collected/measured. From site: "By identifying specific targets for environmental performance and measuring how close each country comes to these established goals, the Pilot 2006 Environmental Performance Index (EPI) provides benchmarks for current national pollution control and natural resource management results. The issue-by-issue and aggregate rankings facilitate cross-country comparisons both globally and within relevant peer groups.…The EPI centers on two broad environmental protection objectives: (1) reducing environmental stresses on human health and (2) protecting ecosystem vitality." | GIS_Data>ENVSData>Other_Sites>Global>Global_EPI>CNTRY_EPI_joined (Jim Proctor Fall 2008).
