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

Methodology: The Blue Technology Barometer 2022/23
Now in its second year, the Blue Technology Barometer assesses and ranks how each of the world’s largest maritime economies promotes and develops blue (sea-centric) technologies that help reverse the impact of climate change on ocean ecosystems and how they take advantage of the oceans. resources to reduce greenhouse gases and other effects of climate change.
To create the index, MIT Technology Review Insights compiled 20 quantitative and qualitative data indicators for 66 countries and territories with coasts and maritime economies. This included analysis of select data sets and primary research interviews with global blue technology innovators, policy makers and international ocean sustainability organizations. Using trend analysis, research, and a consultative peer review process with multiple subject matter experts, weighting hypotheses were assigned to determine the relative importance of each indicator’s influence on blue technology leadership. a country
These indicators measure how each country or territory’s economic and maritime industries have affected their marine environment and how quickly they have developed and deployed technologies that help improve ocean health outcomes. Adherence to policies and regulations, particularly adherence to international fisheries treaties and marine protection laws, were considered factors.
The indicators are organized into four pillars, which evaluate metrics around a sustainability theme. Each indicator is scored from 1 to 10 (10 being the best performance) and weighted by its contribution to its respective pillar. Each pillar is weighted to determine its importance in the overall score. Because these research efforts focus on countries developing blue technology to promote ocean health, the technology pillar ranks highest, with 50% of the overall score.
The four pillars of the Blue Technological Barometer are:
Carbon emissions derived from maritime activities and their relative growth. The metrics in this pillar also assess each country’s efforts to mitigate ocean pollution and improve the health of ocean ecosystems.
Efforts to promote sustainable fishing activities and increase and maintain marine protected areas.
Advances in promoting the development of sustainable ocean technologies in several relevant fields:
- MIT Technology Review Insights’ Green Future Index 2022 net innovation scores.
- A count of patents and technology startups relevant to the sea.
- An assessment of each economy’s use of technologies and technological processes that facilitate ocean sustainability.
Commitment to sign and enforce international treaties to promote ocean sustainability and enforce sustainable fisheries.
