FAME Biodiesel (B100) - Well-to-Wake

FAME biodiesel well-to-wake intensity under FuelEU Maritime: enter the certified E from the Proof of Sustainability and Annex II converts it with Cf 2.834 and LCV 37 MJ/kg (RED Annex III). Without a certificate, or from food and feed crops such as rapeseed, Art. 10(1)(a) counts it as MDO/MGO, 90.77 gCO₂e/MJ.

Fuel masstCertified EgCO₂e/MJTotal GHG intensity from the Proof of Sustainability. Example: 14.9, the RED Annex V Part D default, waste cooking oil biodiesel. Blank counts the fuel as fossil.Made from food and feed cropsStarch-rich, sugar or oil crops grown as a main crop, such as rapeseed, soy or palm (Directive (EU) 2018/2001 Art. 2, point 40). Art. 10(1)(a) counts these as fossil whatever the E.

No certified E entered. Under Art. 10(1)(a) of Regulation (EU) 2023/1805 it is counted as the least favorable fossil pathway for its fuel type, MDO/MGO, ISO 8217 grades DMX to DMB: 90.77 gCO₂e/MJ, no reward factor.

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

FAME biodiesel (waste feedstock) well-to-wake GHG intensity.
