Blended Fuel Well-to-Wake

Energy-weighted WtW GHG intensity for fuel blends - e.g. B30 biodiesel, HVO drop-in, bio-LNG mix, methanol/fossil-methanol blend.

Formula, assumptions, limits

\text{TTW CO}_2 \text{ (t)} = \text{mass} \cdot C_f

\text{Energy (MJ)} = \text{mass (kg)} \cdot \text{LCV (MJ/kg)}

\text{WtW (t CO}_2 \text{e)} = \frac{\text{Energy (MJ)} \cdot \text{WtW factor (g/MJ)}}{10^6}

WtW factors include upstream extraction, processing, transport, plus tank-to-wake combustion and relevant CH₄/N₂O. FuelEU Maritime Annex II publishes the authoritative defaults.

In short

Energy-weighted well-to-wake GHG intensity for fuel blends - biodiesel, HVO, bio-LNG, methanol blends.
