MGO / MDO - Well-to-Wake
Marine Gas Oil and Marine Diesel Oil - distillate fuels with slightly higher Cf (3.206) and LCV (42.7 MJ/kg) than residuals.
Tank-to-wake CO₂
3,206.00t
From Cf per MEPC.364(79)
Energy content
42,700GJ
LCV 42.7 MJ/kg
Well-to-wake GHG
3,868.6t CO₂e
90.6 gCO₂e/MJ WtW
Method
TTW CO₂ (t) = mass × Cf Energy (MJ) = mass (kg) × LCV (MJ/kg) WtW (t CO₂e) = Energy (MJ) × WtW factor (g/MJ) / 1e6
WtW factors include upstream extraction, processing, transport, plus tank-to-wake combustion and relevant CH₄/N₂O. FuelEU Maritime Annex II publishes the authoritative defaults.
