The Environmental Performance Index (link is to the 2008 site, see also our new 2010 design and data) is a global measurement and ranking of the environmental quality and policies of most of the world’s nations. This year’s index was released in Davos in January. We worked with its creators (the Yale Center for Environmental Law and Policy and the Center for International Earth Science Information Network at Columbia University) to make a more accessible and public online manifestation of the index and its components.
One of the goals is to provide access to the index’s subjective, uncertain, and manifold aspects—as well as to the causal and correlative relationships that must be understood in order to improve environmental policies and stir change.
The design emphasizes hyperlinking to allow users to discover the relationships between many aspects of the world’s environment, as well as between countries. It features resizable “wiki charts,” in which every marker on the chart may be a hyperlink to a different page.
