Overview

The Space Sustainability Rating (SSR) is a voluntary rating system providing space actors with a transparent rating and certification system to assess the level of #sustainability of their missions. It also offers practical guidance on how to improve missions’ sustainability performance, with the goal of helping to address the challenges raised by the proliferation of space debris. Developed in the last three years by a consortium including the World Economic Forum, the European Space Agency, the Massachusetts Institute of Technology, BryceTech and the University of Texas at Austin, the rating provides an innovative solution for space operators to support their debris mitigation efforts and increase the sustainability of their missions. All space actors are welcomed to join the SSR. If you wish to learn more about the rating and explore opportunities for engagement please visit our website.
