Investing in Ocean Resilience: a sea change in Climate Finance

A Turning Tide in Climate Finance

A regenerative and sustainable blue economy represents a trillion-dollar frontier investment opportunity with the potential to generate significant returns for investors while advancing social and environmental goals.  

The importance of coastal and ocean ecosystems to the global economy cannot be overstated. Coastal regions are home to almost half of all economic activity and 40 percent of the world’s population. Coastal floods and storm surge already cost the world between USD$10-40 billion dollars a year, projected to reach USD$1 trillion annually by 2050, yet less than one percent of climate finance is invested into coastal nature-based solutions. 

The Ocean is living capital and a highly undervalued asset class. When we invest in its health, we invest in our own. The cost of inaction far outweighs the price of progress. To turn away from the Ocean is to abandon more than USD$8 trillion in potential value. To embrace its promise is to unlock USD$15.5 trillion in benefits, create 12 million jobs by 2030, and bring greater resilience to nations most in need. Yet the science clearly shows that the window for action is closing fast. That is why we must be patient with capital and impatient with action, delivering investment that reduces risk and drives environmental, economic, social and cultural security. But no one sector can go it alone. It is going to take radical collaboration, from beachfront to boardroom.

Who We Are and Why We’re Here

This is where the Ocean Risk and Resilience Action Alliance (ORRAA) comes in. We are a global coalition of more than 120 partners, including banks, insurers, governments, multilaterals, NGOs, locally led SMEs, and academic institutions. All are committed to a common mission: by 2030, to activate at least USD$500 million in investment into finance and insurance products that build the resilience of 250 million climate-vulnerable coastal people in the Global South, and with a focus on Nature-based Solutions. 

Our model works at three interconnected levels. Starting from the ground up, we are building a pipeline of finance and insurance products. We then target the missing middle, bridging policy and capital by strengthening and enabling environments, supporting standards and guidance, and building platforms that bring together investors, communities, project developers, and governments. Finally, we work from the top down to build a capital market for the Ocean — one that blends concessional, philanthropic, and return-seeking capital in ways that align financial incentives with climate and community outcomes. And there are ‘shovel-ready’ investment opportunities right now searching for investors. 

Real Projects, Real Impact

Since its inception, ORRAA has been supporting an incubation and innovation marketplace through small and medium-sized grants to locally led, climate, nature and gender-positive projects. This ranges from microinsurance and savings accounts for small-scale fishers, to coral reef parametric insurance, and blue carbon credit systems rooted in local stewardship. In just the past four years, we’ve supported 50 projects in 30 countries through grants totaling USD$20 million, supporting more than 340,000 people and leveraging an additional USD$65 million of investment.

From Principles to Practice

In 2022, ORRAA and partners (including Salesforce, Conservation International, the World Economic Forum, and The Nature Conservancy) launched the High-Quality Blue Carbon Principles and Guidance. These principles are now being adopted globally by developers, investors, and intermediaries as the basis for development, investment and deployment.

But principles only matter when they’re practiced. That’s why we also developed the High-Quality Blue Carbon Practitioners Guide with Conservation International, released in October 2024, with support from the UK Government’s Blue Planet Fund. 

And to solve the supply-demand gap, we’re developing a new digital tool: The Octopus Platform. Powered by Salesforce’s agentic AI and in partnership with 2050 and unveiled at the Blue Economy and Finance Forum (BEFF) in June 2025, the Octopus Platform will be a global marketplace that connects investors, project developers, and SMEs working on ocean solutions, helping ensure the right money meets the right projects. 

A Step-change for a Sea-change

Finally, working from the top-down, ORRAA’s Sea Change Impact Financing Facility (SCIFF) is developing financial instruments that bridge the ‘valley of death’ between grant funding and investment-readiness by providing a funnel through which they can progress, leading to bankable propositions and investment opportunities across the capital stack. 

Just like a small skiff, or fishing boat, rarely sails alone, the financial instruments being developed are a flotilla working together to deliver the cornerstone elements of a capital market for the Ocean. They include impact funds that invest into Small Island Developing States, a Blue Guarantee Facility, a Blue Bond Accelerator and blended finance vehicle for marine protected areas.

And through our #BackBlue Ocean Finance commitment, which now includes over USD$3.45 trillion in assets under management, we are providing the Ocean with a seat at the table when finance and insurance decisions are made. Those decisions must include stopping financing destructive activities — and not starting new potentially destructive ones, like deep sea mining — and investing for our common future and long-term financial, social and environmental returns. Institutional investors and asset managers need to mobilize across the capital stack — grants, concessional, patient and return-seeking — mobilizing the development of financial instruments which allow millions, billions and then trillions of dollars to flow. 

A Wave of Momentum: UNOC3 and the BEFF

In June 2025, we saw two landmark events: the third United Nations Ocean Conference (UNOC3) in Nice, and the BEFF in Monaco. Together, they signal a new chapter in ocean finance. At the BEFF, over €8.7 billion in public–private and philanthropic investment was committed to 2030, with €1 billion being deployed or investment ready in 2025. Leaders from business, finance, and government outlined a vision for a blue economy that is just, regenerative, and investable.

Then, at UNOC3, the Nice Ocean Action Plan was announced, with key pledges including €1 billion from the European Commission for ocean science and conservation, USD$3.5 billion from development banks to tackle plastic pollution, the creation of the world’s largest marine protected area in French Polynesia, and major funding for ocean governance from Germany, New Zealand, Spain, and Costa Rica. In addition, 19 more countries committed to ratify the High Seas Treaty, bringing us within reach of the 60 needed for it to enter into force, finally offering an international agreement governing the conservation and sustainable use of marine biological diversity in areas beyond national jurisdiction. These binding commitments are reformulating how the global financial system engages with our most vital shared resource.

Looking Ahead: Toward COP30

As we look to COP30 in November in Brazil, hosted under President Lula’s leadership, we expect that climate, nature and ocean finance will come together in the heart of the Amazon, connecting climate justice, biodiversity, and community resilience. The time is now to shift from viewing the Ocean as a resource to be exploited, to understanding it as a regenerative engine for people and planet.  

The wave is building. And it’s going to take all of us — investors, scientists, policymakers, and communities — to ride it together.
