Sox and NOx emissions
Sulphur
The mass of SOx emitted by the vessel is calculated by multiplying
oxides
the given fuel type consumption (in metric tons) with the sulphur
emissions
content of each fuel type (%) and sulphur content factor per metric
(SOx)
ton of fuel.
MT NOx
The sulphur content factor is a 昀椀xed parameter of 1.99782 per
metric ton and, given the fuel type, the sulphur content percentage
is expressed as an absolute value. The emitted mass of SOx will then
be:
Consumption [MT] * Sulphur content [%]* Sulphur Content Factor
1.99782 per mt

ty-based method. This integrates ship-speci昀椀c technical data with

operational parameters for accurate estimates.
MT NOx
NOx emissions (metric tons):
NOx (mt) = Energy Output (kWh) × NOx Factor (g/kWh)/ 10^6
Energy outputs = Energy Output (kWh) = SFOC (g/kWh) × Fuel Consumed (metric tons) × 10^6
