A quarterly analysis published by VesselBot and reported on 29 October 2026 finds that choice of carrier can change a voyage’s Well-to-Wake emissions intensity by as much as 35 per cent on the same trade lanes.
Report findings
VesselBot’s Decoding Maritime Emissions, Q3 2026: Stable Intensity, Diverging Voyage Performance presents quarter-on-quarter measurements and compares carriers operating on four major fronthaul trades, and it records a spread of performance at the voyage level that is material to shippers and charterers. The report uses the Well-to-Wake metric to capture the full-chain carbon intensity attributed to voyages and identifies that, even on identical trade lanes, the difference between the most and least efficient carriers can be significant, up to the 35 per cent cited.
The report title underlines a distinction between aggregate intensity trends and voyage-level variability; while headline intensity at a macro scale is described as stable, the data reveal that individual voyage outcomes diverge between operators. That divergence is presented across the four fronthaul trades the authors examined and is expressed as variation in emissions intensity rather than as a raw emissions total.
Market choice matters
For commercial parties, the finding that carrier selection can materially alter measured Well-to-Wake intensity places carrier choice alongside freight rate and schedule as a variable with environmental consequences. VesselBot’s quarterly series, as summarised by reports, frames the result as an actionable difference in footprint that may affect contractual discussions, sustainability reporting and procurement decisions.
The report’s comparison across multiple carriers on the same trade lanes supplies an empirical basis for buyers to consider emissions intensity as a comparative metric when procuring lift, and for carriers to benchmark voyage performance against peers. The magnitude of the gap cited gives weight to calls for clearer voyage-level measurement and for consistent disclosure practices that allow shippers to make informed choices.
Reporting and transparency
VesselBot has continued a quarterly cadence of analysis with this Q3 2026 instalment, offering an evolving dataset that stakeholders can use to track changes in performance over time; sources published the findings on 29 October 2026. By reporting variability on identical trade lanes, the study highlights the importance of transparent, comparable data if market participants are to align procurement and operational decisions with emissions objectives.
The Q3 2026 report, as relayed by reports, therefore represents both a snapshot and a prompt: a snapshot of diverging voyage performance across four principal fronthaul trades in the last quarter and a prompt for greater uptake of standardised intensity metrics in commercial practice. The figures cited underline that where emissions performance is measurable and comparable, it becomes a factor that can legitimately influence commercial behaviour and disclosure.
