<P> The Environmental Performance Index (EPI) is a method of quantifying and numerically marking the environmental performance of a state's policies . This index was developed from the Pilot Environmental Performance Index, first published in 2002, and designed to supplement the environmental targets set forth in the United Nations Millennium Development Goals . </P> <P> The EPI was preceded by the Environmental Sustainability Index (ESI), published between 1999 and 2005 . Both indices were developed by Yale University (Yale Center for Environmental Law and Policy) and Columbia University (Center for International Earth Science Information Network) in collaboration with the World Economic Forum and the Joint Research Centre of the European Commission . The ESI was developed to evaluate environmental sustainability relative to the paths of other countries . Due to a shift in focus by the teams developing the ESI, the EPI uses outcome - oriented indicators, then working as a benchmark index that can be more easily used by policy makers, environmental scientists, advocates and the general public . Other leading indices like the Global Green Economy Index (GGEI) provide an integrated measure of the environmental, social and economic dynamics of national economies . The GGEI utilizes EPI data for the environmental dimension of the index while also providing a performance assessment of efficiency sectors (e.g. transport, buildings, energy), investment, green innovation and national leadership around climate change . </P>
