Chapter 3. Results

With objective data and clear metrics, the 2018 EPI grades and compares 180 countries on their performance in protecting environmental health and managing natural resources. We score and rank these countries on their environmental performance using the most recent year of data available as well as data from approximately a decade earlier. The state of the world is captured in the Global Scorecard. These results reveal current standings on a core set of environmental issues and identify where progress is or is not being made. The full results of the 2018 EPI, including country and indicator-level analysis, are available at epi.yale.edu. We highlight some of the most important results here in the report.
