The Environmental Emergency Risk Index (EERI) builds upon existing humanitarian, development and environmental performance indices, primarily on InfoRM. InfoRM is a way to measure the risk of humanitarian crises that identifies where crises requiring international assistance may occur and analyses that risk so it can be better managed by everyone.
The Environmental Emergency Risk Index (EERI) looks at the InfoRM risk elements of hazards, vulnerabilities and capacities. It then adds key environmental emergency elements to get an understanding of the countries at risk of anthropogenic disasters.
