Compliance frameworks at a glance

The shipping industry now has five overlapping reporting regimes. Each measures something slightly different, has a different deadline, and goes to a different authority. The platform handles all five from the same dataset.

Comparison

Framework	Authority	Scope	What we calculate	What we generate	Deadline
IMO CII	Flag State / IMO	Ships ≥ 5,000 GT	Attained CII, Required CII, A–E rating, reefer-corrected CII	CII Statement of Compliance	31 March
EU ETS	EU Verifier	Voyages calling EU/EEA ports	Voyage classification, covered CO₂, phase-in factor, EUA cost	EU ETS Report	30 September
FuelEU Maritime	EU Verifier	Energy used in EU/EEA waters	WtW GHG intensity, compliance balance, penalty	FuelEU Report	31 January
EU MRV	EC THETIS-MRV	Voyages calling EU/EEA ports	Voyage-level CO₂, distance, fuel mix	EU MRV Report	31 March
IMO DCS	Flag State / IMO GISIS	Ships ≥ 5,000 GT	Annual fuel consumption, distance, hours underway	IMO DCS Report	31 March

How they interlock

One dataset, five outputs

All five reports are computed from the same consumption logs you upload. Upload once; generate everything.

Year-aware throughout

CII reduction factors, ETS phase-in, FuelEU targets — all change by year. Pick the year and every number updates.

Voyage-leg precision

EU ETS coverage is applied per-leg using BOSP-based segmentation, not whole voyages. The EU MRV report follows the same model.

Audit-ready trace

Every figure is back-traceable to the consumption log row that produced it.
