Alphaliner Prices Maersk's Algeciras Detour at Up to €33m in EU Carbon Savings
Alphaliner data put the first price tag on how EU ETS is pushing container carriers to substitute non-EU hubs for Spanish port calls.
Alphaliner reported on Saturday (2026-08-15) that Maersk's decision to route its MECL container service around Algeciras generated estimated EU ETS-related savings of between €16 million and €33 million — the first time the scale of that routing strategy has been quantified.2
The figures show how the EU Emissions Trading System's extension to shipping is directly reshaping port call decisions. By substituting Tanger Med for Algeciras on the MECL service's westbound leg in late 2024, and then dropping the Spanish port from the eastbound routing in 2025, Maersk reduced its ETS exposure without altering the commercial reach of the trade. The move appears deliberate and replicable.2
The mechanism is straightforward. EU ETS liability applies to voyages between EU ports and to the EU-adjacent portion of voyages arriving from outside the bloc. A vessel calling at a hub just beyond the EU's jurisdiction and handing its cargo to a feeder service can reduce the nautical miles that count toward its compliance obligation. The regulation's architects anticipated this risk from the outset, portogente.com.br reported, yet the policy left the transhipment window open.2
Alphaliner's range — €16 million at the low end, €33 million at the high — is wide enough to warrant caution. The gap reflects the difficulty of reconstructing voyage emissions from public schedule data rather than audited fuel records. These are estimates, not verified compliance figures, and the difference between the two endpoints is not trivial.2
ICE EUA Dec-rolling closed at €81.26 per tonne of CO2 as of Saturday (2026-08-15). At that price, avoiding even the lower bound of the Alphaliner estimate implies a substantial volume of CO2 emissions removed from EU registries, making the compliance arithmetic for competing carriers difficult to dismiss.2
EU ETS revenues grew 11% in 2025 to €43.2 billion, representing 62% of all revenue raised from global carbon pricing schemes that year, according to an International Carbon Action Partnership study cited by Montel on May 21 (2026-05-21). Maritime emissions coverage is a newer and still-expanding component of that total. Transhipment substitution replicated across multiple carriers would erode it, though the source material does not quantify what share of the total shipping contributes.1
Whether rival carriers have adopted the same template is not disclosed in the Alphaliner analysis. The competitive sensitivity is real: disclosing a routing strategy built around ETS avoidance invites regulatory attention, and the European Commission acknowledged the transhipment arbitrage problem when drafting the rules, portogente.com.br reported.2
Eight signals tracked for ICE EUA Dec-rolling are weighted 69% bearish. Lower carbon prices would reduce the per-tonne incentive to route around EU ports. But they would also lower the absolute cost of staying within the EU network, making the Maersk MECL decision harder to evaluate in isolation from where the carbon price settles over coming months.2
For EUA traders, the more immediate question is how the Commission chooses to treat accumulating evidence of port substitution — whether as a compliance anomaly addressable through enforcement, or as a structural flaw requiring a change to the regulation itself. Either outcome shifts the ETS burden for container shipping. Algeciras, a major EU transhipment hub losing calls to a competitor sitting one strait away, now provides the clearest documented case of how carbon pricing is redrawing the economics of European port geography.2
