Methanol - Well-to-Wake by pathway

Grey (fossil natural-gas feedstock), bio (waste-derived), or e-methanol (electrolytic H₂ + captured CO₂). WtW intensities span 1–100 gCO₂e/MJ depending on pathway.

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.
