An international panel for ocean sustainability needs to proactively address challenges facing existing science–policy platforms

Recent calls for an International Panel for Ocean Sustainability (IPOS) to provide consensus-based science advice for global ocean sustainability appeal to the successes of global science–policy platforms, specifically the Intergovernmental Panel on Climate Change (IPCC), the Intergovernmental Science–Policy Platform on Biodiversity and Ecosystem Services (IPBES), and the World Ocean Assessment (WOA)1. A new IPOS may facilitate global ocean sustainability, but only if it proactively addresses the challenges facing existing international science–policy platforms—namely representation, accountability, and politicization.
