Emission factors include both directions, thus return trip need not to be calculated
Ferries carry both passengers and freight; 80% of emissions are allocated to passengers, 20% to freight.
Ropax ships carry both freight and passengers; 84% of emissions are allocated to freight, 16% to passengers.
g/pkm = grams per passenger kilometre (the transport of one passenger over one kilometre)
CO = hiilimonoksidi, HC = hiilivedyt (sisältäen metaanin CH4), NOx = typen oksidit, PM = hiukkaset, CH4 = metaani, N2O = typpioksiduuli, SO2 = rikkidioksidi, CO2 = hiilidioksidi, CO2e = hiilidioksidiekvivalentti, MJ = megajoule
