As carbon rules tighten and alternative-fuel investment accelerates, owners of older ships will face a harder question: does another retrofit extend commercial life, or merely delay an inevitable recycling decision?

Hitesh Vyas, Vice President, Middle East and Green Recycling Coordinator at Wirana Shipping Corporation, examines the factors shaping this decision:

Shipping’s fuel transition is usually discussed as a technology race: which fuel will win, when supply will scale and how quickly new engines can be deployed. Yet the transition will also shape the other end of a vessel’s life. As emissions rules become progressively more demanding, fuel choice and carbon performance will increasingly determine whether an older ship remains commercially viable or is sent for responsible recycling.

The choices facing owners are becoming more complex. LNG, methanol, lower-carbon drop-in fuels and other alternatives each carry different implications for vessel design, fuel availability, tank capacity, operating costs and emissions performance. For newer ships, these considerations can be addressed during the design stage. For older vessels, the decision is more difficult because any investment must be recovered within a much shorter remaining economic life.

This will not happen as a sudden wave. The effect will be gradual, uneven and closely tied to freight markets, but it will compound. For a growing portion of the fleet, the decision to trade on will no longer depend principally on age and earnings. It will depend on whether the vessel can continue to meet regulatory, chartering and financing expectations without absorbing disproportionate capital and operating costs.

The market effect

If fuel and emissions performance are becoming so important, why has recycling supply remained relatively constrained?

The answer lies partly in geopolitics. Longer and less efficient trading patterns have increased tonne-mile demand, while the expansion of the shadow fleet has allowed many older vessels to remain gainfully employed. Higher charter rates have also given owners more room to respond. They can reduce speed, improve voyage planning or fund modifications whose cost can be recovered while earnings remain strong.

That breathing space should not be mistaken for a permanent solution. Slow steaming cannot erase a vessel’s technical limitations, while retrofits become harder to justify when a ship has little remaining life.

Carbon costs

The EU Emissions Trading System has brought carbon directly into voyage economics. It covers 100% of emissions between EU ports and 50% of emissions on voyages between EU and non-EU ports. The phase-in reaches 100% of the 2026 emissions covered at the 2027 surrender deadline, while methane and nitrous oxide are also included from 2026.

Two apparently similar ships may therefore carry materially different compliance costs. A vessel operating on conventional fuel may face a higher carbon exposure than a modern ship using a lower-emission alternative, but converting an existing vessel to LNG, methanol or another fuel can require tens of millions of dollars, depending on its design and the scope of work.

The owner must then consider fuel availability, methane slip in the case of LNG, reduced cargo capacity, time out of service and whether the investment can be recovered before the vessel reaches the end of its commercial life.

The commercial test is therefore not whether a retrofit is technically possible. It is whether the retrofit produces a credible return across the vessel’s remaining economic life.

CII will affect employability

Outside Europe, the Carbon Intensity Indicator is steadily tightening the link between operational efficiency and commercial access. A ship rated D for three consecutive years, or E for one year, must develop an approved corrective action plan. The required reduction against the 2019 reference line rises from 11% in 2026 to 21.5% in 2030.

Owners can respond through speed management, routing, maintenance and energy-saving technologies. But for an older vessel, the cumulative cost and loss of operating flexibility may outweigh the value of another trading year.

The consequences extend beyond regulatory paperwork. Charterers, financiers, insurers and cargo interests increasingly scrutinise environmental performance. A vessel permitted to trade may nevertheless become harder to charter, finance or insure on attractive terms.

The global framework is coming, even if the timetable moves

The IMO’s draft Net-Zero Framework points towards a global fuel-intensity standard and emissions-pricing mechanism calculated on a well-to-wake basis. Formal adoption was adjourned in October 2025, with talks scheduled to resume in 2026. The precise timetable may therefore change, but the direction of travel is clear: lifecycle emissions will increasingly carry a financial value.

That uncertainty should not encourage owners to postpone planning. They must test scenarios covering fuel prices, carbon exposure, trading patterns, retrofit cost and residual life rather than rely on a single forecast.

Some sectors will move first

Container ships and car carriers are likely to feel the transition earlier than several other segments. Their trading patterns, customer visibility and fleet-renewal programmes create stronger pressure to adopt alternative fuels and demonstrate emissions reductions.

As newer dual-fuel vessels enter service, older conventional ships may find themselves pushed towards less attractive employment before being released for recycling.

The decisive period is likely to emerge towards the end of this decade, when tighter CII requirements, regional carbon costs and the prospective global framework begin to overlap. A weaker freight market could accelerate the process by removing the earnings cushion that currently supports older tonnage.

Transition planning

Ship recycling should not be viewed as evidence that decarbonisation has failed. Properly planned and responsibly executed, it is part of fleet renewal. The danger lies in waiting until compliance costs, poor ratings or declining employment leave an owner with limited choices and little negotiating time.

Owners should assess recycling alongside retrofit and continued-operation scenarios well before a vessel reaches that point. The fuel transition will not send every older ship to the recycling yard at once. It will, however, steadily redraw the boundary between assets worth upgrading and those whose steel, equipment and materials can contribute more through safe and environmentally sound recycling.
