The overall rankings tab shows the performance of the examined economies relative to each other and aggregates scores generated across the following four pillars: ocean environment, marine activity, technology innovation, and policy and regulation.
This pillar ranks each country according to its levels of marine water contamination, its plastic recycling efforts, the CO2 emissions of its marine activities (relative to the size of its economy), and the recent change of total emissions.
This pillar ranks each country on the sustainability of its marine activities, including shipping, fishing, and protected areas.
This pillar ranks each country on its contribution to ocean sustainable technology research and development, including expenditure, patents, and startups.
This pillar ranks each country on its stance on ocean sustainability-related policy and regulation, including national-level policies, taxes, fees, and subsidies, and the implementation of international marine law.
