DESCRIPTION:
Navigate through inspiring stories of renewed commitments, strengthened partnerships, and collective action this October!
Read about how Philippine mayors and local leaders from five coastal cities and municipalities pledged to strengthen local actions and solutions to reduce marine plastic pollution. The Mayors’ Conference on Reducing Marine Plastics in Manila brought together key decision-makers to sign the Mayors’ Compact and project agreements under the MOF/PEMSEA ODA Project, marking milestones toward cleaner and more sustainable coasts.
Know more about how PEMSEA reaffirmed its commitment to regional cooperation on sustainable ocean governance through the 34th Expanded Executive Committee (EC) Meeting led by Partnership Council Chair Atty. Jonas Leones, setting a clear implementation pathway toward achieving 2030 global targets.
On the ground, see how empowered communities under the Marine Plastics ODA Project are leading awareness and behavior change efforts across local sites—proving that real progress begins with collective local action.
Learn about the renewed partnership between the Government of Timor-Leste and the PEMSEA Resource Facility through the signing of a revised Memorandum of Understanding in Manila, ensuring continued collaboration for reducing marine plastics in the East Asian Seas region.
Explore the growing impact of the GEF/UNDP/ASEAN Integrated River Basin Management (IRBM) Project across Southeast Asia in their latest newsletter, from river basin consultations in the Philippines to the upcoming project rollout in Malaysia, and multistakeholder workshops advancing the Water-Energy-Food-Ecosystem Nexus approach.
This month, we also congratulate Mr. Yinfeng Guo for his election as IUCN Regional Councillor for South and East Asia, recognizing his long-standing leadership and contributions to regional ocean and coastal governance!

Proceedings of the 2026 PEMSEA Network of Local Governments (PNLG) Forum "Empowering Coastal Cities for a Blue Future"
The 2026 PEMSEA Network of Local Governments (PNLG) Forum, themed “Empowering Coastal Cities for a Blue Future,” was organized by the PEMSEA Network of Local Governments for Sustainable Coastal Development (PNLG), in collaboration with the PEMSEA Network of Learning Centers and the PEMSEA Resource Facility, and hosted by Busan Metropolitan City, Republic of Korea. The forum took place from September 8-10, 2026, at the Paradise Hotel Busan.
PEMSEA eBulletin - October 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.
PEMSEA Regional Methodology for Blue Carbon Project Accounting
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.
INTERNATIONAL SEMINAR ON BLUE CARBON ECOSYSTEM VALUES: Accounting and Crediting Guidance Frameworks
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.
