As a gathering of coastal states, under Japan’s presidency the G20 will specifically work to reduce marine plastic pollution and support marine biodiversity. This policy paper highlights how oceans are governed spaces and points to the key role of the oceans in realizing the SDGs. We argue that the G20 can and should play an important role in addressing major governance gaps in ensuring the sustainable management of oceans.

In the paper we spell out recommendations that we consider realistic, effective, and consistent with the priorities of the Japanese presidency of the G20.
