Earlier this year we redesigned the Environmental Performance Index for 2010. (We also did the 2008 site.) The EPI is a global measurement and ranking of the environmental quality and policies of most of the world’s nations. This new design tries to be accessible to an even wider audience, emphasizes interactive maps more, and lets you see many facets of a country’s performance at a glance. Learning from Fusedspace, the new design also features “trails”, allowing you to “walk” from one country another along many paths, comparing countries along the way.
