IMO DCS carbon factors on modelled sea-route distance at your stated consumption — screening figure for comparison, not an MRV submission. Feed voyage results into the CII and EU ETS estimators for the compliance angle.

Method

IMO carbon factors, eight fuel grades.

Carbon factors

HFO 3.114, MGO/MDO 3.206, LNG 2.750, methanol 1.375 — per the IMO DCS table.

EEOI

CO₂ per tonne-mile of cargo — the operational efficiency index.

AER

CO₂ per deadweight-mile — the metric behind CII ratings.

This tool searches the 5,966-port index — a modelled sea route where the pair is on the 111-port network, a printed NGA Pub. 151 figure where the source lists it, otherwise a labelled straight-line estimate. The distance library covers the same index with the source called out per result; the port distance calculator adds canal-alternative routing on the modelled network.
