The Blue Technology Barometer 2022/23
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.

Overall ranking
Pillars
Comparative
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.
Rank
Score
Ocean Environment
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.

Marine Activity
This pillar ranks each country on the sustainability of its
marine activities, including shipping, fishing, and protected
areas.

Policy and Regulation
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.

About
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 (marine-centered) technologies that help reverse the impact of
climate change on ocean ecosystems, and how they leverage ocean-based resources to reduce greenhouse gases and
other effects of climate change.
To build the index, MIT Technology Review Insights compiled 20 quantitative and qualitative data indicators
for 66 countries and territories with coastlines and maritime economies. This included analysis of select
datasets and primary research interviews with global blue technology innovators, policymakers, and
international ocean sustainability organizations. Through trend analysis, research, and a consultative
peer-review process with several subject matter experts, weighting assumptions were assigned to determine the
relative importance of each indicator’s influence on a country’s blue technology leadership.
These indicators measure how each country or territory’s economic and maritime industries have affected its
marine environment and how quickly they have developed and deployed technologies that help improve ocean
health outcomes. Policy and regulatory adherence factors were considered, particularly the observance of
international treaties on fishing and marine protection laws.
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 is weighted for its contribution to its
respective pillar. Each pillar is weighted to determine its importance in the overall score. As these research
efforts center on countries developing blue technology to promote ocean health, the technology pillar is
ranked highest, at 50% of the overall score.
The four pillars of the Blue Technology Barometer are:
Ocean Environment
Carbon emissions resulting from maritime activities and their relative growth. Metrics in this pillar also
assess each country’s efforts to mitigate ocean pollution and enhance ocean ecosystem health.
Marine Activity
Efforts to promote sustainable fishing activities and increase and maintain marine protected areas.
Technology Innovation
Progress in fostering the development of sustainable ocean technologies across several relevant fields:
Clean innovation scores from MIT Technology Review Insights’ Green Future Index 2022.
A tally of maritime-relevant patents and technology startups.
An assessment of each economy’s use of technologies and tech-enabled processes that facilitate ocean
sustainability.
Policy and Regulation
Commitment to signing and enforcing international treaties to promote ocean sustainability and enforce
sustainable fishing.
