Methodology: The Blue Technology Barometer 2022/23
The Blue Technology Barometer, now in its second year of operation, ranks and assesses how each of the largest companies in the world.
Maritime economies promotes and develops blue technologies (marine-centered), that help reverse the negative impact of
Climate change and ocean ecosystems: How they use ocean-based resources for greenhouse gas reduction
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 selected
Datasets and interviews with global blue tech innovators, policymakers, et al.
International ocean sustainability organizations. Through trend analysis, research, as well as a consultative approach
Peer-review process with many subject matter experts. Weighting assumptions were assigned in order to determine the
The relative importance of each indicator’s impact on a country’s blue technology leadership is discussed.
These indicators show how each country’s maritime and economic industries have impacted its economy.
How quickly they have developed and deployed technologies to improve the marine environment
Health outcomes Consideration was given to regulatory compliance factors and policy, in particular the observation of
International treaties on marine protection and fishing.
The indicators are divided into four pillars that evaluate metrics related to sustainability themes. 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 in order to determine its importance in the overall score. These research results are available here
Blue technology is a technology pillar that promotes ocean health and countries are focusing their efforts to develop it.

The Blue Technology Barometer’s four pillars are:
The relative growth of maritime activities and carbon emissions. This pillar also contains metrics
Assess each country’s efforts in protecting the oceans and improving ocean ecosystem health.
Efforts to encourage sustainable fishing and to increase and maintain marine protected zones.
There has been progress in encouraging the development of sustainable ocean technologies in several 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
