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.
