♦ Activity: Fuel combustion - Biomethane

♦ Greenhouse gas: Carbon dioxide from biogenic sources ( CO2 )

► Year 2010 —

● Greenhouse gas emission estimate —

Amount: 0 tonne of CO2 From biogenic materials (0 tonne CO2 Eq.)
Basis: Calculation
Calculation: [Fuel combustion] * [Heat content] * [Fuel CO2 emission]

● Activity level used in calculations —

Activity: Fuel combustion = 0 scf of Biomethane
Basis: Data
Reference: Not Applicable.
