IMO CII ANNUAL FORECAST

Plan a vessel’s carbon intensity

Use a full calendar year of distance and consumed fuel. The result uses the IMO supply-based capacity × distance measure.

Vessel & year

Capacity means DWT for cargo ship types and GT for passenger and ro-ro ship types.

Reference year Ship type Gross tonnage GT · applicability Capacity DWT Total annual distance NM

Use the vessel’s full IMO DCS year, including consumption in port. The distance is total reported distance, including movement while not under way where applicable; it is not one voyage’s routed distance.

Annual fuel consumption

Enter tonnes consumed across the full year; use 0 for grades not used. At least one grade must be positive.

HFO tonnes · 3.114 tCO₂/t LFO tonnes · 3.151 tCO₂/t MGO / diesel tonnes · 3.206 tCO₂/t LNG tonnes · 2.750 tCO₂/t Other documented fuel tonnes Other fuel CO₂ factor tCO₂/t

CO₂ only: CII does not use CH₄ or N₂O CO₂e in this calculation. Use a documented fuel conversion factor for other fuels. Blend factors and allowed voyage adjustments require separate verification.
