Situated at the heart of Southeast Asia (SEA), which holds the world's highest blue carbon stocks, Singapore is a fast-growing regional hub for blue carbon expertise and innovation. Building on Singapore's established carbon services ecosystem and ongoing research programmes, WWF Singapore and Hatch Blue, supported by EDB, has launched Blue Catalyst in 2026 - a new open innovation challenge seeking start-ups and innovators to develop technological solutions for high-quality blue carbon credits across Asia.

Overview of blue carbon and challenges in blue carbon project development
Blue carbon ecosystems, such as mangroves, seagrasses, peatlands and coastal wetlands, are among the planet’s most powerful natural climate solutions, storing carbon up to four times more efficiently than terrestrial forests. Mangroves buffer coastal communities from storms, support rich biodiversity, and in Singapore alone, provide habitat for over 3,000 insect species1. These ecosystems not only sequester carbon at scale but also safeguard US $800 billion in food security and livelihoods annually. Yet, 40% of mangrove-dependent species are already threatened globally.
High-integrity carbon markets can generate reliable revenue streams by pricing both the carbon sequestered and the co-benefits to communities and biodiversity.
However, blue carbon project development is often challenged by complex implementation and monitoring, reporting and verification (MRV). Projects require highly tailored approaches for restoration and protection and have long gestation and monitoring needs as mangroves have slower rates of carbon accumulation. These challenges are compounded with various risks for failure, such as low survival rates of mangrove seedlings and vulnerability of coastal habitats to sea level rise and ocean acidification due to climate change. MRV for blue carbon projects can also take 1-2 years before credit issuances and require extensive sampling and sophisticated measurement approaches and equipment. As up to two-thirds of carbon stock in blue carbon projects are found below ground, it is also challenging to use satellite or remote sensing technologies to scale or speed up the MRV process.
As demand for nature-based credits rises, the success of blue carbon projects hinges on trust and scalability, making innovation, technology, and collaboration more critical than ever.
