The Global Commons Stewardship Index is a composite of the latest breakthroughs in sustainability indicators, focusing attention on how countries are af­fecting the Global Commons both within their borders and through impacts embodied in trade and consumption (so-called “international spillovers”).

The Index aims to inform actions to achieve major international agreements, including the Sustainable Development Goals (SDGs), the Paris Climate Change Agreement, and the Con­vention on Biological Diversity.

The Global Commons Stewardship Index is a collaboration between the SDSN, the Yale Center for Environmental Law & Policy, and the Center for Global Commons at the University of Tokyo.
