Energy-weighted well-to-wake intensity of a fuel blend, entered as one row per component by mass, as FuelEU counts a blend such as B30. This tool takes no certified E, so every biofuel and RFNBO component counts as its fossil fallback under Art. 10(1); the FuelEU GHG intensity calculator takes the certified values.
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 of a fuel blend by component, with uncertified biofuel counted as fossil under FuelEU Art. 10(1)(a).
