The 2012 Environmental Performance Index (EPI) and Pilot Trend EPI (Trend EPI) rank 132 countries on 22 performance indicators in ten policy categories and two overarching objectives that reflect facets of Environmental Health and Ecosystem Vitality. These indicators provide a gauge of how close countries are to environmental policy goals. The EPI’s proximity-to-target methodology facilitates cross-country comparisons as well as analysis of how the global community is doing collectively on each particular policy issue. The pilot trend EPI reflects changes in environmental performance over the period 2000-2010.
