FuelEU Deadline Looms as High Bunker Costs and Slow Charterer Action Stall Shipping Emissions Progress

Estimated reading time: 3 minutes

The maritime industry is entering a critical compliance period as operators face mounting pressure to cut emissions while grappling with high fuel costs, uneven adoption of efficiency technologies, and limited progress from charterers during the latest reporting cycle.

New industry data released this month shows that large shipowners and charterers achieved only modest emissions improvements in 2025 despite increased use of biofuels and energy saving technologies. The findings arrive as FuelEU Maritime enters its first full compliance cycle, with penalties for non compliance in the 2025 reporting period due to be issued by 30 June 2026.

The combination of regulatory deadlines, elevated bunker prices, and slow investment decisions is creating a challenging environment for shipowners, carriers, and cargo interests across Europe and key global trade lanes. Industry analysts say operational efficiency measures are delivering measurable benefits, but deployment remains too limited to meet longer term decarbonization targets.

According to DNV, shore power is rapidly evolving from a voluntary environmental initiative into a regulatory requirement. European ports, California, and several Asian jurisdictions are expanding requirements for vessels to connect to onshore electricity while at berth to reduce emissions and local air pollution.

The shift is occurring as FuelEU Maritime introduces financial consequences for operators failing to meet greenhouse gas intensity targets. For many shipping companies, compliance planning has moved from a strategic discussion to an operational necessity.

The regulatory burden extends beyond vessel owners. Charterers increasingly influence fuel choices, voyage planning, and operational efficiency, making their participation critical to achieving emissions targets. However, industry reporting indicates progress among charterers remains slower than many regulators and shipowners had anticipated.

High marine fuel prices remain a significant obstacle to faster adoption of low carbon fuels and retrofit programs.

Singapore bunker indications on 24 June showed very low sulfur fuel oil trading at approximately $711.50 per metric ton, while marine gasoil approached $936.50 per metric ton. Separate market assessments placed Singapore VLSFO closer to $762.00 per metric ton and Rotterdam VLSFO at approximately $687.50 per metric ton.

The elevated cost environment is forcing many operators to balance regulatory compliance against commercial realities. Retrofit projects, alternative fuels, and new efficiency technologies often require substantial capital commitments at a time when freight markets remain volatile across several shipping segments.

For breakbulk, project cargo, and heavy lift operators, the challenge can be particularly complex because vessel utilization patterns and specialized cargo requirements often limit operational flexibility.

Industry attention continues to focus on technologies capable of reducing fuel consumption without requiring immediate fuel switching.

DNV estimates that wider adoption of shore power for vessels above 5,000 gross tons could reduce fuel oil consumption by roughly 3.5%, equivalent to approximately 29 million tonnes of carbon dioxide annually. However, infrastructure limitations and inconsistent port availability continue to constrain implementation.

Meanwhile, Lloyd’s Register reports growing interest in propulsion energy saving devices, hull coatings, wind assisted propulsion systems, and other efficiency measures. Adoption is increasing across both newbuild and retrofit markets, but deployment remains uneven across the global fleet.

Longer term policy signals remain clear. The International Maritime Organization expects its Net Zero Framework, approved in 2025, to enter into force in 2027 with the first year of application scheduled for 2028. At the same time, green shipping corridor initiatives continue to expand, including new pilot projects and the recently announced Brazil to Belgium corridor consortium, reinforcing industry expectations that regulatory and commercial pressure to decarbonize will continue to intensify.
