The Blue Technology Barometer is a ranking of 66 coastal
countries and territories on their progress and commitment
toward protecting ocean sustainability. It measures the
degree to which economies are prioritizing the protection of
ocean health, through sustainable marine activity, blue
innovation, and policy implementation.
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
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.
