Lead PI: Dr. Alexander de Sherbinin , Alexander de Sherbinin

Unit Affiliation: Center for International Earth Science Information Network (CIESIN)

September 2021 - June 2022
Project Type: Research


The 2022 Environmental Performance Index (EPI) ranks 180 countries on 40 performance indicators in the following 11 issue categories: air quality, sanitation and drinking water, heavy metals, waste management, biodiversity and habitat, ecosystem services, fisheries, acid rain, agriculture, water resources, and climate change mitigation. These categories track performance and progress on three broad policy objectives, environmental health, ecosystem vitality, and climate change. The EPI's proximity-to-target methodology facilitates cross-country comparisons among economic and regional peer groups. The data set includes the 2022 EPI, component scores, and time-series source data.

The 2022 EPI is the result of a collaboration of more than a decade between the Yale Center for Environmental Law and Policy (YCELP), Yale University, and the Columbia University Center for International Earth Science Information Network (CIESIN). The data collection overview (including an archive of biennial EPI data releases and reports for 2006, 2008, 2010, 2012, 2014, 2016, 2018, and 2020), including data for download, and maps are available at our main program web site https://sedac.ciesin.columbia.edu/data/collection/epi.
