EU ETS puts a direct price on maritime carbon, and CII ratings carry corrective-action obligations that escalate with poor performance. For a mid-market operator, the gap between an E and a D is measurable — yet most are still managing it in spreadsheets.
Attained vs. required Carbon Intensity Indicator per vessel, with a year-end A–E rating projection against MARPOL Annex VI thresholds.
Actual carbon cost to date plus a year-to-date-pace projection, so you see annual liability before it lands.
Model speed reduction, hull cleaning, propeller polishing and weather routing — with their CII point gain and euro impact — to plan your way out of a poor rating.
Four headline metrics — total vessels, vessels needing attention, total ETS exposure, fleet average rating — sit above a sortable inventory. At-risk vessels and aggregate euro exposure are the first things you see.

Three headline cards — CII rating with urgency cue, attained intensity in gCO₂/dwt·nm against the required threshold, and ETS exposure at current pace — plus a CII Performance Scale that plots the vessel along the A–E band visually.

Each voyage shows route, distance, average speed, fuel burned, ETS cost and status — filterable by completed, planned or non-EU. Inline editing and CSV import/export keep data entry fast.

Toggle measures and watch the carbon-intensity trajectory respond in real time — actual, projected, optimised and required lines across the year against the A–E zones. See exactly which combination crosses a vessel from E into D, and what it costs to get there.

Technical specs, maintenance and efficiency records (hull cleaning, dry dock, EEXI/EEDI verification) and ownership data — completeness flagged, and exportable to PDF for sharing or filing.

IMO Carbon Intensity Indicator (CII, per MEPC.337/338/339(76)) and the EU Emissions Trading System (Directive 2023/959), including voyage scope classification across INTRA-EU, FROM-EU, INTO-EU and NON-EU legs.

No. Fathom is a calculation and decision tool. It gives you defensible numbers and quantified options; the regulatory decisions remain yours.
Fathom is built to complement it — focused on the operational decisions and cost exposure that reporting tools leave out, like which interventions move a vessel between rating bands.
