Public investment in the blue economy has nearly doubled in the past decade, but funding still falls short of global needs

The global ocean economy reached USD 2.6 trillion in gross value added in 2020, yet investment in its sustainable transition remains critically low. While tracked ocean finance flows grew to USD 9.18 billion in 2023, this represents less than 2% of the estimated USD 550 billion needed annually by 2030. Financing is heavily reliant on official development assistance (ODA), which accounted for 55% of flows in 2023, but recent ODA cuts by major donors like Germany, the US, the UK, Japan, and France threaten progress. Most funding has historically targeted maritime transport, fisheries, and marine protection, while decarbonisation and adaptation sectors, such as offshore energy and disaster preparedness, remain underfunded. Despite this, investing in the ocean-climate nexus could reduce the 2050 emissions gap by 35% on a 1.5°C pathway and yield global benefits five times the value of the investment.

• There is a massive disparity between the annual investment required for the sustainable ocean economy by 2030 and the actual tracked funding. While an estimated USD 550 billion is needed per year, tracked investments in 2023 were only USD 9.18 billion, which is less than 2% of the requirement.
• Ocean finance is disproportionately dependent on official development assistance (ODA), which provided approximately 55% of total tracked flows in 2023. However, sustainable ocean economy initiatives received only 1.4% of total ODA that year.
• Recent fiscal and political pressures have led to a 23% decline in overall ODA between 2024 and 2025, with over 95% of these cuts coming from France, Germany, Japan, the UK, and the US, risking a subsequent decline in ocean financing.
• Funding for the sustainable ocean economy has been concentrated in maritime transport, fisheries, and marine protection, while climate-critical sectors like offshore energy and disaster preparedness have received minimal support.
• Investing in the ocean-climate nexus offers substantial environmental and economic returns, including the potential to reduce the 2050 emissions gap by 35% on a 1.5°C pathway and generate global benefits at a rate of five times the invested value.
• The cost of inaction regarding ocean protection is estimated at USD 75-85 billion annually. Specifically, unsustainable fisheries management could cost businesses between USD 53–83 billion in lost profits globally.
• Major financial institutions and initiatives are providing significant but varied support: the World Bank's blue economy portfolio exceeded USD 11.1 billion in FY2025, and the European Investment Bank provided EUR 12.9 billion in lending between 2021 and 2025.
