Environmental Performance Measurement

The world has entered a new era of data-driven environmental policymaking. As demonstrated by the quantitative targets recently established by initiatives like the UN Sustainable Development Goals, the Paris Climate Agreement, and the Kigali Amendment to the Montreal Protocol, governments are increasingly being asked to validate their environmental performance with data. A more empirical approach to environmental protection promises to make it easier to spot problems, track trends, highlight best policy practices, and optimize investments in sustainable development.  

YCELP has a longstanding commitment to enabling and advancing data-driven environmental policymaking. As the flagship project of our center, the Environmental Performance Index (EPI) has shaped debates and informed governments around the globe on how to improve country-level performance against environmental benchmarks. The EPI is a biennial analysis that ranks 180 countries on 32 environmental issues like climate change, environmental health, and biodiversity. These indicators track trends in environmental performance and provide scorecards on how close countries are to meeting established environmental targets. Our transparent and robust analyses provide practical guidance for countries that aspire to move toward a sustainable future.
