The International Association of Ports and Harbors (IAPH) has welcomed the landmark agreement reached last Friday at the United Nations’ International Maritime Organization (IMO), which outlines a new package of greenhouse gas (GHG) emissions reduction regulations, known as the “IMO net-zero framework.” The agreement, advanced by MEPC83 for adoption later this year, sets a course for global implementation by 2028.
Global Economic Measure to Drive Low-Carbon Fuel Adoption
The new economic measure is seen as a vital step in the decarbonization of maritime shipping, which currently handles 90% of global trade and contributes approximately 3% of global GHG emissions. The framework is expected to encourage the development and adoption of low and zero-carbon fuels, and will fund infrastructure through the IMO Net-Zero Fund.
Funds collected through the measure will be allocated to:
-
Research, development, and deployment of zero and near-zero GHG emission technologies.
-
Infrastructure and equipment development, especially in maritime, coastal, and port areas.
Alignment with IAPH’s Long-Term Proposals
The agreement aligns closely with IAPH’s previous proposals and contributions, including a comprehensive study presented at MEPC 82 on infrastructure investment needs—particularly in developing countries. IAPH’s original proposal emphasized the need for inclusive, global funding to support maritime decarbonization across all regions.
Guidelines and Port Collaboration
Following formal adoption in October 2025, IAPH will play a key role in shaping the guidelines needed to support the IMO net-zero framework. These will provide clarity for stakeholders and facilitate smoother global implementation.
In parallel, IAPH will:
-
Expand the IMO-recognized Environmental Ship Index (ESI) to reward GHG emission reductions beyond compliance.
-
Encourage voluntary cooperation between ports and shipping via the IMO ports resolution.
-
Offer financial incentives, such as reduced port fees, to greener vessels.
Port Readiness and Cross-Sector Collaboration
To assist ports in adapting to new fuel technologies, IAPH will continue working through its Clean Marine Fuels and Port Readiness Level Working Groups. These groups are developing tools and frameworks to guide ports through complex transitions involving fuel bunkering, cargo operations, and safety protocols.
Moreover, IAPH is collaborating on CEM-HUBS, a joint initiative with the International Chamber of Shipping (ICS). The project seeks to break industry silos and connect the maritime and energy sectors to scale up the production, transportation, and use of low-carbon fuels.
A Call for Global Certainty and Investment Support
IAPH Managing Director Patrick Verhoeven emphasized the need for regulatory certainty and global standards, especially as ports face multi-billion dollar investment decisions.
