The Philippines is stepping up efforts to protect its coastal ecosystems. The government recently advanced its National Blue Carbon Action Partnership (NBCAP) Roadmap. This plan aims to conserve and restore mangroves, seagrass beds, and tidal marshes. It also explores biodiversity credits — a new market linked to nature conservation.
Blue carbon refers to the carbon stored in coastal and marine ecosystems. These habitats can hold large amounts of carbon in plants and soil. Mangroves, for example, store carbon at much higher rates than many land forests. Protecting them reduces greenhouse gases in the atmosphere.
Biodiversity credits are a related concept. They reward actions that protect or restore species and ecosystems. They work alongside carbon credits but focus more on ecosystem health and species diversity. Markets for biodiversity credits are being discussed globally as a complement to carbon markets.
Why the Philippines Is Targeting Blue Carbon
The Philippines is rich in coastal ecosystems. It has more than 327,000 hectares of mangroves along its shores. These areas protect coastlines from storms, support fisheries, and store carbon.
Mangroves and seagrasses also support high levels of biodiversity. Many fish, birds, and marine species depend on these habitats. Restoring these ecosystems helps conserve species and supports local food systems.
The NBCAP Roadmap was handed over to the Department of Environment and Natural Resources (DENR) during the Philippine Mangrove Conference 2026. The roadmap is a strategy to protect blue carbon ecosystems while linking them to climate goals and local livelihoods.
DENR Undersecretary, Atty. Analiza Rebuelta-Teh, remarked during the turnover:
“This Roadmap reflects the Philippines’ strong commitment to advancing blue carbon accounting and delivering tangible impact for coastal communities.”
Edwina Garchitorena, country director of ZSL Philippines, which will oversee its implementation, also commented:
“The handover of the NBCAP Roadmap to the DENR represents a turning point in advancing blue carbon action and strengthening the Philippines’ leadership in coastal conservation in the region.”
The plan highlights four main pillars:
- Science, technology, and innovation.
- Policy and governance.
- Communication and community engagement.
- Finance and sustainable livelihoods.
These pillars aim to strengthen coastal resilience, support community well‑being, and align blue carbon action with national climate commitments.
What Blue Carbon Credits Could Mean for Markets
Globally, blue carbon markets are growing. These markets allow coastal restoration projects to sell carbon credits. Projects that preserve or restore mangroves, seagrass meadows, and tidal marshes can generate credits. Buyers pay for these credits to offset emissions.
According to Grand View Research, the global blue carbon market was valued at US$2.42 million in 2025. It is projected to reach US$14.79 million by 2033, growing at a compound annual growth rate (CAGR) of almost 25%.
The Asia Pacific region led the market in 2025, with 39% of global revenue, due to its extensive coastal ecosystems and government support. Within the market, mangroves accounted for 68% of revenue, reflecting their high carbon storage capacity.
Blue carbon credits belong to the voluntary carbon market. Companies purchase these credits to offset emissions they can’t eliminate right now. Buyers are often motivated by sustainability goals and environmental, social, and corporate governance (ESG) standards.
Experts at the UN Environment Programme say these blue habitats can capture carbon 4x faster than forests:
Why Biodiversity Credits Matter: Rewarding Species, Strengthening Ecosystems
Carbon credits aim to cut greenhouse gases. In contrast, biodiversity credits focus on saving species and habitats. These credits reward projects that improve ecosystem health and may be used alongside carbon markets to attract finance for nature.
Biodiversity credits are particularly relevant in the Philippines, one of 17 megadiverse countries. The nation is home to thousands of unique plant and animal species. Supporting biodiversity through market mechanisms can strengthen conservation efforts while also supporting local communities.
Globally, biodiversity credit markets are still developing. Organizations such as the Biodiversity Credit Alliance are creating standards to ensure transparency, equity, and measurable outcomes. They want to link private investment to good environmental outcomes. They also respect the rights of local communities and indigenous peoples.
These markets complement carbon markets. They can support conservation efforts. This boosts ecosystem resilience and protects species while also capturing carbon.
Together with blue carbon credits, they form part of a broader nature-based solution to climate change and biodiversity loss. A report by the Ecosystem Marketplace estimates the potential carbon abatement for every type of blue carbon solution by 2050.
Science, Policy, and Funding: The Roadblocks Ahead
Building blue carbon and biodiversity credit markets is not easy. There are several challenges ahead for the Philippines.
One key challenge is measurement and verification. To sell carbon or biodiversity credits, projects must prove they deliver real and measurable benefits. This requires science‑based methods and monitoring systems.
Another challenge is finance. Case studies reveal that creating a blue carbon action roadmap in the Philippines may need around US$1 million. This funding will help set up essential systems and support initial actions.
Policy frameworks are also needed. Laws and rules must support credit issuance, protect local rights, and ensure fair sharing of benefits. Coordination across government agencies, local communities, and investors will be important.
Stakeholder engagement is key. The NBCAP Roadmap and related forums involve scientists, policymakers, civil society, and private sector partners. This teamwork approach makes sure actions are based on science, inclusive, and fair in the long run.
Looking Ahead: Coastal Conservation as Climate Strategy
Blue carbon and biodiversity credits could provide multiple benefits for the Philippines. Protecting and restoring coastal habitats reduces greenhouse gases, conserves species, and supports local economies. Coastal ecosystems also provide natural defenses against storms and rising seas.
If blue carbon and biodiversity credit markets grow, they could fund coastal conservation at scale while supporting global climate targets. Biodiversity credits could further enhance ecosystem protection by linking nature’s intrinsic value to market mechanisms.
The market also involves climate finance and corporate buyers looking for quality credits. Additionally, international development partners focused on coastal resilience may join in.
For the Philippines, the next few years will be critical. Implementing the NBCAP roadmap, establishing credit systems, and strengthening governance could unlock new opportunities for climate action, sustainable development, and regional leadership in blue carbon finance.
