DESCRIPTION:
This paper seeks to provide a review of the development of port sustainability in concept and in practice, with a specific focus on waste management systems within ports. The handling and treatment of ship waste discharge has evolved over time, as shipping has changed and as the understanding of the human impact on the environment has increased.
The general trend among international regulations surrounding waste is to shift it away from disposal at sea and towards disposal on land. There is also a trend towards increasing the efficiency and potentially recyclability of waste, meaning actions such as waste segregation are becoming increasingly important.
Such trends mean greater need at ports for efficient and effective waste management systems, which must receive increasing levels of waste from ships, even as the global shipping industry continues to expand. Waste management has become a key role of ports, with such waste needing to be removed from ships through port just like goods and passengers.
Efficient waste management provides a good service for ports with positive economic, environmental, and reputational benefits. Those with the best capacity to deal with a particular ship’s waste is more likely to see that ship call there. Ports which can rapidly shift waste will have quicker ship turnaround, decreasing wasted ship time and increasing port throughput.
At the same time, as waste management may prove an economic burden, imposing sanitary and safety concerns as well as more direct disposal costs, for both ports and shipping, it needs to take place within a robust regulatory and monitoring framework. Ports and ships working to meet established standards are at a disadvantage if others are avoiding compliance. As a result, improved sustainability is best achieved through broader engagement in developing regulations and monitoring and enforcement mechanisms through transparent stakeholder consultation including port authorities, shipping representatives, local communities living near the ports, and local and national authorities.
Around the world, there are many innovative practices to improve waste operations. Increased digitization allows for earlier notification of incoming waste, better monitoring of waste flows, and easier sharing and analysis of data. Improved segregation on both ships and in ports allows for waste to be more efficiently, and more effectively, treated. Some waste may even undergo minimal treatment while on ships. New waste fee structures accommodating such changes and other considerations are needed to create appropriate incentive structures.
As with regulations, innovations can benefit from enhanced cooperation among stakeholders. Ports can engage with governments and the private sector to prompt attention to shipping-related innovation. Mixed funding schemes, such as public-private partnerships, provide more opportunities for ports to improve and futureproof their activities.
As understanding and research and innovative technologies around waste management continue to increase, national and international expectations are likely to change with changing knowledge. At the same time, shipping volumes will likely keep rising as the global economy expands.
As a hub of the global shipping network, the fate of the seas of East Asia is intertwined with the sustainability of global shipping. While this will be a challenge, it also provides an opportunity, for the ports around these seas to become global leaders in port sustainability innovation.

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.
The 2026 PEMSEA Network of Local Governments for Sustainable Coastal Development (PNLG) and PEMSEA Network of Learning Centers (PNLC) Joint Learning Forum
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.

PEMSEA Blue Carbon Program Updates
PEMSEA eBulletin - September 2026
September connected regional decisions with local action—from a new declaration in Busan to community-led work across the region.
In Busan, the 2026 PNLG General Assembly adopted the Busan Declaration on Promoting Local Coastal Resilience and Sustainable Blue Economy and welcomed Atauro Island, Timor-Leste, as the Network’s newest member. Meanwhile, PEMSEA Founder Dr. Chua Tia-Eng returned to the PEMSEA Resource Facility for a discussion with colleagues on PEMSEA’s history, lessons, and continuing role in advancing sustainable coastal and ocean governance.
PEMSEA project updates include the GEF/UNDP/ASEAN IRBM Project advanced planning for food and biodegradable waste management in the Pasac-Guagua Watershed, while the PRICELESS Project brought stakeholders together in Regions 3 and 4A to tackle challenges and priorities for the Philippine Rise.
In the Philippines and Timor-Leste, MEP partners under the MOF/PEMSEA Marine Plastics ODA Project mobilized communities, schools, government agencies and civil society organizations for International Coastal Cleanup activities, turning awareness of marine plastic pollution into action on the ground.
