The OECD is building a comprehensive database on the Sustainable Ocean Economy. Reliable and timely data on the natural asset base and the sustainability of the ocean economy, the well-being and resilience of coastal communities, and the health of marine ecosystems are scarce. There is equally a need to monitor policies and finance to speed up the transition. This work will help meet the demands of the international community for a better evidence base to support decision making, including SDG 14. The database is currently under development.
