Proceedings of the 5th PEMSEA Network of Learning Centers (PNLC) Executive Committee Meeting 2026

From local solutions to international dialogues, October saw PEMSEA bringing coastal and ocean governance conversations to the forefront.

On the international stage, PEMSEA brought regional perspectives to the 11th International Waters Conference in Indonesia, the 2nd APEC Ocean Resilience Enhancement Conference, and Asia-Pacific Ocean Week 2026. Through these engagements, PEMSEA shared experiences and practical approaches to integrated coastal management, ocean resilience, and source-to-sea governance, contributing East Asian Seas perspectives to wider discussions on shared environmental challenges and regional cooperation.

At the regional level, the PEMSEA Executive Committee (EC) met online for the 36th EC Meeting  to review institutional governance measures, discuss regional priorities, and look ahead to key Partnership milestones taking shape for 2027.

In the Philippines, PEMSEA continued to strengthen local partnerships through the PRICELESS Project and MOF/PEMSEA Marine Plastics ODA Project through continued collaboration with its partners and stakeholders.

Different platforms, shared priorities. This month, PEMSEA's engagements showed how regional experience can inform international conversations, how partnerships can shape collective priorities, and how cooperation can support solutions on the ground.

A Harmonized Guide for Estimating Carbon Stocks, Sequestration, and GHG Reductions in Coastal Ecosystems

Differences in measurement methods, carbon pool inclusion, and monitoring frameworks have made blue carbon projects in East Asia hard to compare. PEMSEA’s Regional Methodology addresses this with a single accounting framework for mangroves, seagrasses, and salt marshes. It is designed to be compatible with national greenhouse gas inventories and technically aligned with voluntary carbon credit certification requirements.

The Main Methodology sets out project eligibility and additionality, boundaries and stratification, baseline and project scenarios, uncertainty management, a tiering system, leakage, permanence and risk management, and monitoring, reporting, and verification. Five technical annexes provide the field and analytical detail:

• Annex A – Mangrove Ecosystems: carbon stock and sequestration assessment methods
• Annex B – Seagrass Ecosystems: carbon stock and sequestration assessment methods
• Annex C – Salt Marsh Ecosystems: carbon stock and sequestration assessment methods
• Annex D – Mapping Blue Carbon Ecosystems: remote sensing, validation, and change detection
• Annex E – Monitoring Environmental Parameters: the environmental conditions that influence blue carbon ecosystems

The methodology was prepared under the guidance of the Blue Carbon Technical Working Group of the EAS Partnership Council, with contributions from experts across the region. It is intended for project developers, national agencies, researchers, and verifiers working to bring high-integrity blue carbon projects to market.

The Korea Maritime Institute (KMI) and Partnerships in Environmental Management for the Seas of East Asia (PEMSEA) convened the International Seminar on Blue Carbon Ecosystem Values in Busan, Republic of Korea. The seminar gathered representatives from six East Asian countries, academic institutions, and regional partners to validate enhancements to the Regional Blue Carbon Accounting Protocol (RBCAP), review biodiversity accounting and crediting approaches, and define PEMSEA’s role in governance, verification, and market development. Key outcomes included expert recommendations to strengthen the RBCAP, shared insights on biodiversity crediting pathways, and a clearer vision of PEMSEA’s added value as a regional platform for advancing blue carbon and biodiversity markets.

• PEMSEA Blue Carbon Program Updates

   

The 2026 PEMSEA Network of Local Governments for Sustainable Coastal Development (PNLG) and PEMSEA Network of Learning Centers (PNLC) Joint Learning Forum, themed “Empowering Coastal Cities for a Blue Future,” was organized by the PNLG and PNLC in collaboration with the Korea Maritime Institute (KMI), the Korea Institute of Ocean Science and Technology (KIOST), Coastal 500, and the PEMSEA Resource Facility. The Forum was hosted by the Metropolitan City of Busan, Republic of Korea. The Joint Learning Forum took place on 8 September 2026 at Paradise Hotel Busan as part of the 2026 PNLG Annual Forum (8-10 September 2026). It featured two panel discussions: Local Pathways for Blue Carbon and Nature-Based Solutions, and Capitalizing on Coasts: Financing and Innovating Local Blue Economies.
