Blue Economy Startups

The ocean covers over 70% of the Earth's surface, regulates our climate, supports livelihoods for over three billion people, and provides vital ecosystem services. Yet overfishing, plastic pollution, acidification, and climate change are pushing marine systems to the brink.

The global Blue Economy is projected to reach $3 trillion by 2030, driven by investments in sustainable seafood, ocean conservation, marine renewables, and circular innovations. New technologies and regenerative approaches are essential to restoring ocean health while building resilient coastal economies.

This infographic highlights pioneering startups advancing the Blue Economy across four key innovation categories:

  • Sustainable Seafood & Aquaculture: Startups creating alternative seafood solutions, scaling regenerative aquaculture, and improving food security while reducing pressure on wild fisheries.
