A vessel over 5000GT calling at the Malta Freeport today carries a carbon compliance bill under the EU Emissions Trading System (ETS) that did not exist two years ago. By 2027, that bill will cover 100% of verified CO₂ emissions on intra-EU voyages, up from 40% in 2024. At the same time, the IMO’s Net-Zero Framework (NZF) remains politically stalled whilst the Strait of Hormuz, through which one-fifth of globally traded oil passes, is under geopolitical stress. All these factors are outrightly intensifying shipping costs. Malta is not just observing these developments but is directly exposed to all three pressures.

The EU ETS extension to maritime shipping is an active compliance cycle with a mechanical phase-in that increases cost obligations year-on-year. From 2026, it also expands to cover methane and nitrous oxide. When the EU ETS was introduced in 2024, the surcharge added just 1% to average shipping costs largely masked by the Red Sea crisis pushing freight rates upward. By 2026, with full 100% compliance now in force and methane and nitrous oxide added to scope for the first time, industry analysis by Searoutes puts that figure at between 6% and 12% of total shipping costs. Hapag-Lloyd has confirmed its ETS surcharge will rise by approximately 45% in 2026 driven by:        i) full ETS coverage, ii) methane and nitrous oxide expansion, and iii) rising carbon allowance prices. Maersk likewise signal substantial hikes from these same factors. These two major shipping lines operate approximately 30% of global container capacity. For an island economy where over 90% of goods arrive by sea, these are not futile percentages but ones that translate directly into the cost of every imported good.     

The structural risk for Malta, however, is not only cost; it is competitive distortion. Peer-reviewed analysis shows that for EU transhipment hubs competing with nearby non-EU ports, diversion becomes economically viable at carbon prices below €25 per tonne. Current prices have, at times, exceeded three times that level. The Malta Maritime Forum’s (MMF) Brussels mission in March 2026 presented hard evidence of exactly this. Transhipment activity is visibly shifting to expanding non-EU hubs along the North African coast, as carriers re-route to avoid ETS costs paradoxically generating the same emissions outside EU jurisdiction while reducing southern EU ports to secondary feeder roles.

The MMF’s formal recommendations to the Commission included:

• A temporary freeze on ETS and FuelEU Maritime for shipping pending a global IMO measure,
• Exclusion of high-transhipment EU ports from the definition of “port of call” where transhipment exceeds 65% of activity,
• Extended derogations for major island states, and
• A Commission commitment to withdraw regional schemes once a global system is in place – amongst other recommendations.

These recommendations were grounded in a formal political process. Maltese MEP Daniel Attard issued a question to the Commission earlier this year raising precisely this concern. That for island states permanently dependent on maritime connectivity and without viable modal alternatives, ETS price signals do not drive behavioural change but rather drive inequality, inflationary pressure and a loss of competitiveness. Commissioner Hoekstra’s answer acknowledged a Central Bank of Malta estimate of consumer price increases of 0.11–0.25% linked to ETS shipping costs and noted that Malta receives additional allowances given its large maritime sector. The response, however, stopped short of any structural commitment from the Commission which is why the MMF’s empirical intervention was both necessary and well-timed.

The 2026 ETS review is the first mandatory reassessment of the maritime extension. It is also, given the current political climate, the clearest moment for Malta to influence the policy since the EU ETS Directive came into force.

FuelEU Maritime adds a second layer of obligations on top of ETS: a well‑to‑wake greenhouse‑gas‑intensity trajectory tightening toward near‑zero by mid‑century. Together, the two regimes create a multi‑track compliance burden that was originally expected to be unified under a global IMO baseline. However, that baseline has not yet entered into force and, quite frankly, by the likes of it, will not be coming into force anytime soon.

The IMO-NZF was technically approved at the Marine Environment Protection Committee(MEPC) 83 in April 2025. The extraordinary MEPC session convened in October 2025 to adopt it was adjourned for a year. The constraint is predominantly political, and it has hardened since. Two pre-session papers submitted ahead of MEPC 84 (27 April – 1 May 2026) represent the most serious challenge to date. The United States (MEPC 84/7/41) calls: for the NZF to be scrapped entirely, for the reconvened extraordinary session not to resume, and for any future framework to require explicit ratification by each member state a procedure that, in practice, can delay entry into force by decades.

Argentina, Liberia, and Panama (MEPC 84/7/38) take a different but equally consequential line, they retain the NZF’s shell but strip out its economic core entirely: no IMO fund, no pricing mechanism, and a Global Fuel Intensity target that adjusts based on whatever the market is already delivering. That two of the world’s three largest flag states are aligned against the NZF is not incidental. A framework that cannot attract the support of the flag states which constitute the majority of the world’s fleet (and which in turn confer MARPOL jurisdiction over same) faces a clear problem that no amount of technical refinement can resolve.

Over 90% of Malta’s goods arrive by sea. Geopolitical disruption in the Strait of Hormuz complicates every layer of this picture: longer voyages, higher bunker costs, war‑risk premia, and reduced scheduling reliability. The combined effect of regulatory cost, geopolitical pressure, and the absence of a global pricing counterweight should not be viewed as separate issues. For an island economy, they act together and the impact is significantly amplified.

Regulatory fragmentation is not a transition phase. For now, it is the reality. The EU’s Fit for 55 agenda is active and strengthening, while the global framework intended to establish a level playing field is facing its most serious political challenge yet. What unfolds at MEPC 84 at the end of April will determine whether the NZF framework survives in any meaningful form, or whether Malta, along with every other EU island economy, will be left carrying a regional compliance burden, without global alignment, for years to come.
