Established in 2000, Matthew Schwartz Design Studio (www.ms-ds.com) is a branding and interactive agency who works with leading nonprofits and academic institutions to design solutions that help tackle some of the world’s greatest challenges; combining expertise in strategy, design and technology to connect the dots between engagement and impact. 

Methods

The Environmental Performance Index (EPI) is constructed through the calculation and aggregation of 20 indicators reflecting national-level environmental data. These indicators are combined into nine issue categories, each of which fit under one of two overarching objectives. Click on "Learn More" to explore the complete methods.

Data Explorer

The EPI Data Explorer allows users to dynamically investigate global data: Compare environmental performance with GDP, population, land area, or other variables; create a chart that highlights all 178 ranked countries, only those in a specific region, or a custom-defined group. There's a lot more to the data than rankings, so dive in.
