Environmental Performance Index (EPI)
Yale University's Environmental Performance Index (EPI) ranks countries on performance indicators covering both environmental public health and ecosystem vitality.
The 2012 Country Performance Map visualises EPI indicators using Google Maps. The map shows a heat map of each country's EPI ranking and allows the user to view the EPI's other performance indicators via a drop-down menu.
Users can mouse-over a country to reveal the country's ranking and ranking trend in an information window. Clicking on a country takes the user to the country's dedicated country profile page where all the performance indicators for the country can be viewed on one page.
The Environmental Performance Index (EPI) is a method of quantifying and numerically benchmarking the environmental performance of a country'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 U.N. Millennium Development Goals.
In the 2012 EPI ranking, the top five countries were Switzerland, Latvia, Norway, Luxembourg, and Costa Rica. The bottom five countries were South Africa, Kazakhstan, Uzbekistan, Turkmenistan, and Iraq. The United Kingdom was ranked in 9th place, Japan 23rd place, Brazil 30th, the United States 49th, China 116th, and India came in 125th. The top five countries based on their Pilot Trend EPI were Latvia, Azerbaijan, Romania, Albania and Egypt.
