The EEOI is calculated based on IMO MEPC.1/Circ.684, with the
EEOI only uses CO2 factor

The carbon factors used are as follows:
Heavy fuel oil: 3.1144
Light fuel oil: 3.151
Diesel oil: 3.206

Annual
The AER is calculated based on MEPC.336(76) guideline, with the
AER only uses CO2 factor
E昀케ciency
formula:

Ratio (AER)
AER for the 昀氀eet = (Annual fuel consumption * carbon factor of the
fuel) /total transport work (Distance sailed * average DWT of G2
Ocean’s 昀氀eet).
The carbon factors used are as follows:
Heavy fuel oil: 3.1144
Light fuel oil: 3.151
Diesel oil: 3.206

The SOx emissions are divided by transport work (distance*cargo
transport
carried) to give a fair comparison year by year.
