For the ninth year in a row, SEI has been ranked among the top think tanks in the world working on environment policy and practice.

The index is based on a survey of thousands of journalists, policy-makers, donors and topic and regional specialists around the globe, using a detailed list of criteria including leadership and staff; quality and reputation of the research produced; policy impact and recognition; convening power; innovation; inclusiveness; and communications.

From a pool of 8248 think tanks, the index produces rankings by region and expertise. There is also a section on the most significant think tank publications, in which SEI’s work on the Sustainable Development Goals is featured.

SEI Deputy Director and Research Director, Åsa Persson, said the think tank ranking is a validation of SEI’s core approach. “On one hand, we function as a think tank, working closely with policy-makers and development practitioners, and engaging with industry and financial actors,” she said. “But in every case, we ground our engagement in our own rigorous scientific research. That combination adds real value in supporting policy for sustainable development.”
