The blue economy is the sustainable use of ocean resources for economic prosperity. It covers everything from fisheries and shipping to offshore energy, marine tourism, and biotechnology — all while preserving the health of ocean ecosystems.
Oceans are an economic powerhouse. The global blue economy is worth an estimated $2.5 trillion annually and supports over 350 million jobs. Shipping alone moves 90% of global trade by volume. Offshore wind energy is the fastest-growing segment, with investments exceeding $50 billion in 2024.
For countries like Bangladesh, India, and small island nations, the blue economy is transformative. Bangladesh's Bay of Bengal maritime area is larger than its land area. India has a 7,500 km coastline with enormous potential for fisheries, port development, and marine energy. The World Bank is actively financing blue economy projects to combat overfishing, plastic pollution, and coastal degradation.
