For the first time, an entire industry will be governed by a global emissions pricing mechanism. That industry is maritime.
From 2028, vessels will begin paying for their greenhouse gas emissions under a framework being finalised by the International Maritime Organization (IMO). Carbon pricing is expected to start between USD 100 and 380 per tonne of CO₂ equivalent and rise over time. This policy will apply across international operations, regardless of location or flag.
No other industry has faced a globally coordinated emissions price. Maritime is now the front line of climate-driven market reform.
Impacts for maritime operators
-
Emissions become a direct operating cost. A vessel emitting 10,000 tonnes of CO₂ each year could face up to USD 4 million in additional annual costs.
-
Carbon intensity becomes a commercial metric. Vessels with lower emissions will be cheaper to operate and more attractive to charterers focused on decarbonising supply chains.
-
Early movers benefit. Operators that act now can reduce exposure, secure compliance credits, and align with ESG-linked financing and procurement trends.
Electrification as a strategic lever
Electrification won’t solve every challenge, but it is one of the most practical tools available today to reduce emissions from vessel operations.
-
Battery-electric and hybrid systems are already in use across port service vessels, offshore wind support, coastal vessels and ferries. An increasing number of vessels are also implementing shore power to reduce emissions while in port. These solutions can significantly reduce emissions, particularly where clean grid power is accessible.
-
The focus shifts from global fuel logistics to local infrastructure. Ports and energy providers become essential enablers of vessel decarbonisation.
-
Electrification provides a technical and commercial foundation for future fuels. Even where full electric operation isn’t feasible, hybrid systems and charging can reduce reliance on conventional fuels and prepare for integration with future fuels as they become available.
Ports and power networks step into a new role
As emissions become monetised, clean energy becomes a compliance tool. High-capacity port electrification enables operators to reduce costs and improve environmental performance. It also opens up new revenue models for energy providers, who can supply clean power into a high-value, regulated market.
Ports are no longer just logistics hubs. They are part of the decarbonisation infrastructure.
Oceon’s role
At Oceon, we’re building the integrated systems that support this transition. Our Electrified Ocean Networks (EONs) connect vessels, ports, and energy markets into coordinated energy systems. We help reduce emissions, unlock investment, and enable commercial pathways for maritime electrification at scale.
We see this not only as a regulatory response but as a chance to reshape how energy is delivered and used across the maritime sector.
