Environmental Performance Index (EPI)

The 2018 Environmental Performance Index (2018EPI) 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 24 indicators tracked in ten issue categories:

Air Quality
Water and Sanitation
Heavy Metals
Biodiversity and Habitat
Forests
Fisheries
Climate and Energy
Air Pollution
Water Resources
Agriculture

For more information on the indicators, download the 2018 EPI Technical Appendix version 5.

The EPI utilizes a proximity-to-target methodology focused on a core set of environmental outcomes linked to policy goals. The 2018 EPI includes 180 countries based on data availability.
