HVO / Renewable Diesel - Well-to-Wake

HVO well-to-wake intensity under FuelEU Maritime: enter the certified E from the Proof of Sustainability and Annex II converts it with Cf 3.115 and LCV 44 MJ/kg. At the RED default E of 16.0 for HVO from waste cooking oil the result is 17.25 gCO₂e/MJ; without a certificate Art. 10(1)(a) counts it as MDO/MGO, 90.77.

FuelHVO

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

TTW CO2 (t)=mass⋅Cf\text{TTW CO}_2 \text{ (t)} = \text{mass} \cdot C_fEnergy (MJ)=mass (kg)⋅LCV (MJ/kg)\text{Energy (MJ)} = \text{mass (kg)} \cdot \text{LCV (MJ/kg)}WtW (t CO2e)=Energy (MJ)⋅WtW factor (g/MJ)106\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

HVO (hydrotreated vegetable oil) marine well-to-wake GHG intensity.
