Pilot 2006 Environmental Performance Index

The Pilot 2006 Environmental Performance Index was formally released in Davos, Switzerland, at the annual meeting of the World Economic Forum this past January. The EPI is a new effort to gauge countries against a set of 16 specific indicators tracked in six policy categories: Environmental Health, Air Quality, Water Resources, Productive Natural Resources, Biodiversity and Habitat, and Sustainable Energy. The world map shown here combines the indicators to portray overall environmental health by nation. You might think of the colors as proxy values for sustainability. Coincidentally (or not?) yellow, red, & orange nations appear to be places from which large numbers of people migrate to new homes in the blue and green. Data lovers, hang on. More posts on the index and underlying environmental trends are coming.
