The 2012 Environmental Performance Index (2012 EPI) centers on two broad environmental protection objectives: (1) reducing environmental stresses on human health, and (2) promoting ecosystem vitality and sound natural resource management. These are gauged using 22 indicators tracked in ten policy categories:
- Environmental Burden of Disease
- Air Pollution (effects on human health)
- Water (effects on human health)
- Air Pollution (ecosystem effects)
- Water (ecosystem effects)
- Biodiversity and Habitat
- Climate Change
The EPI utilizes a proximity-to-target methodology focused on a core set of environmental outcomes linked to policy goals. The 2012 EPI includes 132 countries based on data availability.
The Pilot Trend Environmental Performance Index (Trend EPI) ranks countries on the change in their environmental performance over the last decade. As a complement to the EPI, the Trend EPI shows who is improving and who is declining over time.
