ethanol
liquid biofuelDESNZ 2025 Bioethanol. Scope-1 CO2e (CH4+N2O; biogenic CO2 netted to zero) is a separate factor from the biogenic combustion CO2 ('outside of scopes'). IPCC 2006 Biogasoline NCV 27.0 MJ/kg (wide range 13.6–54.0, 'ethanol theoretical'), raw CO2 70,800 kg/TJ.
- Biogenic CO2 from ethanol combustion is reported on a SEPARATE line ('outside of scopes'), not silently zeroed.

CO₂ ≠ CO₂e — separate metrics, never converted into one another.Biogenic CO₂ is listed on its own line: the carbon still leaves the stack, but it is accounted for separately from fossil CO₂ rather than added to it. What these metrics mean →

Emissions
CO₂ and CO₂e are separate — never derived from each other.
Energy density
Energy per unit of mass or volume.
Assumptions
- density: assumed ethanol density 794 kg/m³ at 15 °C (fuel-properties basis)
- heating value basis: energy on LHV/NCV basis, 26.8 MJ/kg
- heating value basis: energy on HHV/GCV basis, 29.7 MJ/kg
