INDICATORS/The Environmental Performance Index (EPI)

The 2016 Environmental Performance Index is a project lead by the Yale Center for Environmental Law & Policy (YCELP) and Yale Data-Driven Environmental Solutions Group at Yale University (Data-Driven Yale), the Center for International Earth Science Information Network (CIESIN) at Columbia University, in collaboration with the Samuel Family Foundation, McCall MacBain Foundation, and the World Economic Forum.

These indicators are combined into nine issue categories, each of which fit under one of two overarching objectives. This section provides an overview of how the EPI is calculated.
