This collection includes an archive of 2006, 2008, 2010 and 2012 Environmental Performance Index (EPI) reports and data sets.
The EPI utilizes a proximity-to-target methodology focused on a core set of environmental outcomes linked to policy goals. The Pilot Trend Environmental Performance Index (Trend EPI), introduced in 2012, ranks countries on the change in their environmental performance over the period 2000-2010.
