About the Index
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 Blue Technology Barometer measures the performance of countries and territories across four pillars:
Ranks CO₂ emissions from marine activity, water contamination, and plastic recycling.
Ranks the sustainability of marine activities, such as shipping and fishing.
The Blue Technology Barometer was developed through the analysis of select datasets and primary research interviews with global blue technology innovators, policymakers, and international ocean sustainability organizations.
It quantifies the economies of 66 countries and territories with large or economically significant ocean coastlines along four separate pillars: ocean environment, marine activity, technology innovation, and policy and regulation.
Within each pillar, a series of indicators—a list of qualitative and quantitative factors—were then selected and populated. Through trend analysis, research, and a consultative peer-review process with several of the subject matter experts interviewed for this report, weighting assumptions were assigned to determine the relative importance with which each indicator and pillar influenced a country’s blue technology leadership.
MIT Technology Review was founded at the Massachusetts Institute of Technology in 1899. We are a leading voice on climate change issues with a dedicated topic area on our website for the global climate emergency, including innovations that may accelerate decarbonization and national climate policy initiatives. The Massachusetts Institute of Technology is strongly committed to climate change: in May 2021, MIT shared a new, decade-long plan aimed at fighting climate change and helping to decarbonize the economy by 2050.
MIT Technology Review Insights is the custom publishing division of MIT Technology Review. We conduct qualitative and quantitative research and analysis worldwide and publish a wide variety of content, including articles, reports, infographics, videos, and podcasts.
