EU ETS Review 2026: Broader Scope, Greater Need for Clarity
July 21, 2026

What the European Commission’s proposal could mean for shipowners and managers

The European Commission has published its proposal for the 2026 review of the EU Emissions Trading System (EU ETS).

For European industry, the proposal includes a more gradual transition, additional decarbonisation support and greater flexibility around the reduction of free allowances.

For shipping, the direction is different.

Maritime transport remains firmly within the existing EU ETS framework, while an expansion of the scope is being considered. That could bring additional vessel categories, voyages and emissions into the system.

The central question is therefore no longer only how much carbon will cost.

It is whether a broader maritime scope will be accompanied by simpler reporting, proportionate verification and clearer commercial responsibility.

Maritime remains within the EU ETS

The European Commission has chosen to keep maritime transport within the current EU ETS structure rather than moving smaller vessels into a separate carbon-pricing system.

This provides continuity for companies already working with:

  • emissions monitoring;
  • annual verification;
  • allowance procurement;
  • surrender obligations;
  • charterparty cost allocation.

At the same time, continuity does not mean that the existing scope will remain unchanged.

The proposal creates a pathway for additional vessel categories to be brought into the EU ETS. It may also lead to changes in the treatment of voyages, port calls and transshipment activity.

For shipowners and managers, this means that existing compliance processes may need to support a larger part of the fleet.

Possible expansion to smaller vessels

One of the most relevant elements for shipping is the potential reduction of the current vessel threshold for certain ship types.

General cargo and offshore vessels between 400 and 5,000 GT have already been included in the EU Monitoring, Reporting and Verification framework. This means that the emissions-data foundation for a possible future inclusion in the EU ETS is already being established.

The final vessel categories, timelines and compliance requirements have not yet been confirmed.

However, the direction is clear: smaller vessels may increasingly become part of European carbon regulation.

This is particularly relevant for small and medium-sized shipowners and managers, where compliance responsibilities are often handled by lean teams.

For these companies, the administrative impact can be just as significant as the cost of purchasing allowances.

Broader coverage must remain workable

Expanding the EU ETS to additional vessels can increase the share of maritime emissions covered by carbon pricing.

But broader coverage will only work if the compliance framework remains proportionate.

Applying the same level of administration to a small vessel as to a large oceangoing fleet could create unnecessary complexity and cost.

The practical design therefore matters.

Shipping companies need clarity on:

  • which vessels will be included;
  • which voyages and emissions will fall within scope;
  • when the new requirements will take effect;
  • which data must be monitored and reported;
  • how verification will be organised;
  • who will be responsible for the administrative process;
  • how compliance costs can be passed on contractually.

A wider scope without simpler processes could lead to duplicated data handling, additional manual checks and more fragmented communication between owners, managers, charterers and verifiers.

The objective should not only be to include more emissions.

It should also be to create a system that companies can operate efficiently.

The impact goes beyond annual compliance

The EU ETS review is not simply a reporting matter.

Changes to vessel and voyage scope can affect operational, financial and commercial decisions throughout the year.

Vessel and voyage exposure

A company needs to understand which voyages generate an obligation and how that obligation develops over time.

Exposure can depend on:

  • the vessel’s size and type;
  • the departure and arrival ports;
  • port calls during the voyage;
  • the party responsible for the vessel’s operation;
  • the contractual arrangement with the charterer.

This requires visibility at vessel, voyage and fleet level rather than a single annual calculation.

EUA procurement

More vessels in scope may increase the number of allowances a shipping company needs to purchase and surrender.

Companies will need to forecast their EUA requirements, understand the associated cash-flow impact and decide when allowances should be purchased.

The EUA market is influenced by policy developments, auction supply, weather, energy demand and financial positioning.

That makes procurement timing and cost visibility increasingly important.

Charterparty cost allocation

The company responsible for compliance administration is not always the party that should ultimately bear the cost.

Owners and charterers therefore need clear reporting and contractual arrangements.

A broader scope increases the importance of:

  • accurate voyage reports;
  • transparent emissions calculations;
  • clear cost-allocation mechanisms;
  • timely communication between parties;
  • supporting data that can withstand commercial scrutiny.

Internal workload

Every additional vessel can create recurring administrative work.

This may include:

  • data collection;
  • emissions calculations;
  • verifier communication;
  • invoice preparation;
  • EUA transfers;
  • internal approvals;
  • reconciliation with charterers.

For companies with limited internal resources, the quality of the workflow becomes critical.

A more targeted ETS for industry and shipping

The Commission’s proposal suggests that the future EU ETS will not simply become stricter or softer across every sector.

Instead, the system is becoming more targeted.

European industry may receive more time, conditional support and additional access to decarbonisation funding.

Shipping, meanwhile, is likely to remain firmly within the carbon-pricing framework and may face broader coverage.

This difference is important.

It shows that the impact of the EU ETS review will not be evenly distributed across the economy.

For shipping companies, the focus should therefore be on the specific operational and commercial consequences for their fleets.

Opportunities for maritime decarbonisation

The EU ETS review also creates opportunities.

A greater share of carbon-market revenues may be used to support:

  • cleaner marine fuels;
  • vessel-efficiency technologies;
  • alternative propulsion;
  • emissions-reduction projects;
  • infrastructure for maritime decarbonisation.

This could help accelerate investment in cleaner shipping.

However, the practical value will depend on how funding programmes are designed.

Important questions include:

  • which technologies will qualify;
  • whether smaller shipping companies can access support;
  • how complex the application process will be;
  • whether projects need to be commercially proven;
  • when funding will become available.

For many owners, access and simplicity will be just as important as the amount of funding available.

Preventing overlapping carbon costs

The relationship between the EU ETS and future global maritime regulation also requires attention.

A future carbon-pricing mechanism under the International Maritime Organization could create overlap with the European system.

The same emissions should not be priced twice without a clear coordination mechanism.

Shipping is a global industry. A fragmented regulatory landscape could lead to:

  • multiple emissions calculations;
  • separate reporting obligations;
  • conflicting responsibility structures;
  • overlapping financial exposure;
  • additional administrative costs.

Greater alignment between European and international regulation would help companies manage their obligations more efficiently.

The proposal is not yet final

The European Commission’s publication is the start of the legislative process.

The European Parliament and EU Member States will now review and negotiate the proposal.

The final scope, implementation dates and detailed compliance requirements may still change.

Shipowners and managers should not wait for every detail to be final before assessing their potential exposure.

Companies can already begin reviewing:

  • vessels that may fall within a lower threshold;
  • the quality and availability of emissions data;
  • gaps in current reporting processes;
  • charterparty arrangements;
  • expected EUA requirements;
  • internal responsibilities;
  • the capacity of existing teams and systems.

Early preparation does not mean acting on assumptions.

It means understanding where regulatory change could create operational or financial pressure.

From regulatory change to practical insight

The EU ETS review confirms that carbon exposure will remain a permanent part of shipping economics.

For companies already within the system, a wider scope may increase compliance volume and financial exposure.

For companies currently outside the EU ETS, the review could introduce a completely new regulatory obligation.

In both cases, the priority is the same:

Understand what applies, quantify the exposure and create a workable process before the obligation becomes urgent.

Navaris supports shipowners and managers by translating carbon regulation into practical operational and financial insight.

Through a combination of technology and direct maritime expertise, we help companies:

  • monitor vessel and voyage exposure;
  • forecast EU ETS costs;
  • prepare reporting and cost allocation;
  • understand EUA requirements;
  • support allowance procurement;
  • assess regulatory developments;
  • reduce unnecessary manual work.

Conclusion

The EU ETS review could significantly expand the number of maritime vessels and voyages covered by European carbon pricing.

That may strengthen the system and create new opportunities for cleaner shipping.

But broader coverage must be accompanied by proportionate reporting, practical verification and clear commercial responsibility.

For shipowners and managers, the issue is no longer only the EUA price.

It is how vessel scope, compliance workload and financial exposure come together.

More scope requires more clarity.
Not more duplicated compliance.
