Environmental Performance Index

The 2022 Environmental Performance Index (EPI) offers a data-rich sustainability scorecard that translates cutting-edge scientific findings into policy insights. Using 40 performance indicators, the EPI ranks 180 countries on their national efforts to protect environmental health, enhance ecosystem vitality, and mitigate climate change. These indicators measure how close countries are to meeting internationally established sustainability targets for specific environmental issues.

With a methodology refined over two decades that builds on the most recent data, the EPI enables decision-makers to recognize the drivers of top-tier performance. Analysis of the EPI data demonstrates that financial resources, good governance, human development, and regulatory quality matter for elevating a country’s sustainability. Highlighting these connections, the EPI helps to promote sustainable development in support of a more environmentally secure and equitable future.
