In advance of this year’s report, which will be unveiled during a live online event beginning at 11 a.m. Thursday, we spoke with Daniel Esty, the Hillhouse Professor of Environmental Law and Policy at Yale and one of the lead authors of the report.

The 2020 Environmental Performance Index will be announced during a live, online event beginning at 11 a.m. this Thursday, June 4 [Register here]. During the webinar, the EPI team, led by Zach Wendling, the project director, will discuss the 2020 results and rankings — and offer insights on what the scorecard says about the pathway to a sustainable future both for individual nations and the world as a whole.
Why is the EPI important?
What difference has the EPI made since it was first unveiled in the year 2000?
Esty: Going back 20 years, the EPI has helped to trigger a fundamental change in how environmental policymaking gets done — shifting the standard practice from a mode of anecdotal decision making toward a much more analytically rigorous and data-driven approach to problem identification, assessment of policy options, and empirically grounded assessment of whether government programs have delivered the intended results. It has demonstrated the logic of a more empirical approach to environmental policymaking and provided the foundation on which the UN’s 2015 commitment to 17 Sustainable Development Goals, underpinned by 169 quantitative targets has been built.
How have national leaders used the insights to change policy?
Esty: The EPI has helped to signal what sustainability leadership looks like — and national officials often point to what others are doing in their push to adopt new approaches to sustainability challenges. Other leaders across the world have used the EPI results to call out problems — particularly policy shortcomings that have not gotten adequate attention. We witnessed a dramatic example of this signaling effect two years ago in India where the 2018 EPI highlighted the fact that Indian cities had become the most polluted places in the world — triggering dozens of newspaper stories, a parliamentary inquiry, and vigorous public debate. The 2020 EPI, which will be revealed on June 4, will have a new #1 nation based largely on that country’s cutting-edge efforts to respond to climate change — which we hope will inspire more ambitious programs of greenhouse gas emissions control across the world.
Are there any trends you’ve identified over the years?
Esty: Perhaps the most notable trend across the years is that nations that pursue environmental policy with care and consistency and a commitment to following data-driven analysis outperform those that are more haphazard in their approach to sustainability. In fact, the primary policy lesson from the 2020 EPI Report is that good “governance” represents the most significant determinant of top-tier results. Real public participation in the policy process, a carefully structured regulatory strategy, open debate over goals and programs, the presence of a lively media and vibrant NGOs, and a commitment to the rule of law all correlate with out-performance over time.
Can you speak to any of the key findings this year?
Esty: The EPI team will be hosting a webinar on Thursday, June 4 to reveal the results. We invite people to register for this event and to join us. As noted above, a new #1 country will be revealed with that country’s environment minister on the ZOOM call to help explain how it achieved its leadership position. But without revealing any secrets, we can say that good governance and consistent effort over many decades across the full spectrum of sustainability challenges pays off.
