We help to create opportunities for investors to be part of building a sustainable blue future by mainstreaming investments in our ocean.


We help address the global climate and biodiversity challenge by supporting sustainable Nature-based Solutions with financial longevity.


We support developers and enterprises so they can develop and build a strong business case to attract private investments.

Blue Natural Capital

Blue Natural Capital (BNC) is the natural capital found in coastal and marine environments – in ecosystems such as coral reefs, mangroves and seagrass beds. Unfortunately, this capital is undervalued in many places around the globe and continues to be lost and degraded at an alarming rate.

Why is BNC important?

BNC ecosystems provide invaluable resources and livelihoods to local communities including tradable products, an abundance of seafood, and tourism revenue. They improve water quality and act as a buffer to storm surges.  Also referred to as blue carbon, they are efficient at removing carbon from the atmosphere but are sources of significant carbon emissions if destroyed.  They are vital refuges for biodiversity and a key component of a healthy ocean.

What is IUCN doing?

The investment in sustainable coastal protection and management brings tangible benefits to local communities that are often heavily dependent on the health and abundance of the marine resources. Together with partners, IUCN is building the business case for investing in our ocean. We work with projects on the ground to develop sustainable businesses with private investor appeal, and support the broader finance and conservation community with valuable lessons on investment opportunities.

The Blue Natural Capital Financing Facility (BNCFF) supports the development of sound, investable BNC projects with clear ecosystem service benefits, based on multiple income streams and appropriate risk-return profiles.

The BNCFF is managed by IUCN and funded by the Government of the Grand Duchy of Luxembourg.

The Blue Carbon Accelerator Fund (BCAF) supports the development of blue carbon restoration and conservation projects in developing countries and helps pave the way for private sector finance.

The BCAF is managed by the IUCN and funded by the Australian Government.
