Data Explorer

The Environmental Performance Index provides a ranking that shines light on how each country manages environmental issues. However, the EPI ranking is only one way to look at important global data. This EPI Data Explorer allows users to investigate the global data more dynamically: Compare environmental performance with GDP, population, land area, or other variables; create a chart that highlights all 178 ranked countries -- or only those in a specific region, or a custom-defined group. There's a lot more to the data than rankings, so dive in.
