Environmental Performance Measurement

The world has entered a new era of data-driven environmental policymaking. With the UN’s 2015 Sustainable Development Goals, governments are increasingly being asked to explain their performance on a range of pollution control and natural resource management challenges with reference to quantitative metrics. A more data-driven and empirical approach to environmental protection promises to make it easier to spot problems, track trends, highlight policy successes and failures, identify best practices, and optimize the gains from investments in environmental protection.

For years, data-driven policymaking has been a longstanding and core focus area for YCELP thanks to our flagship project, the Environmental Performance Index (EPI). Now in its twentieth year, the biennial report ranks 180 countries on 24 performance indicators across 10 issue categories covering environmental health and ecosystem vitality. Over the course of its history, the EPI has influenced policymakers and shaped debates across the globe as to how bestimprove country-level performance against environmental benchmarks.
