We organised an extra roundtable, focused on youth, which took place on March 22 and 23 in Bonn, on the margins of the UN SDG Action Campaign’s Global Festival of Action in Bonn. This briefing was the key document to prepare for this roundtable, and presents the key rationale for and added value of producing free, publicly accessible league tables to help investors, civil society, and governments assess corporate performance in delivering the Sustainable Development Goals. The topics and questions listed within do not represent prescriptive aspects for discussion, but rather considerations to help kickstart the formal consultation. This document will be updated and expanded based on feedback, with the aim of developing recommendations around the need to develop, fund, house, and safeguard SDG-related league tables within a formal institution, tentatively described here as the World Benchmarking Alliance.
