The Blue Economy refers to the sustainable use of ocean resources for economic growth, improved livelihoods, and ocean ecosystem health. It recognizes the ocean as a source of value beyond extraction—including carbon sequestration, biodiversity, tourism, transportation, and renewable energy.
Originally defined by the World Bank, the Blue Economy includes both traditional and emerging marine sectors that prioritize sustainability and inclusivity.
“The blue economy is the sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of the ocean ecosystem.” – World Bank

Key Sectors of the Blue Economy
Here are some of the major areas driving growth in the Blue Economy:
