♦ Category: Energy

IPCC: 1A3bi - Fuel Combustion Activities - Transport - Road Transportation - Cars
Sector: Transportation : On Road : Light-duty Vehicles : Passenger Cars

♦ Activity: Fuel combustion - Renewable Diesel

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

► Year 2006 —

● 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 gal of Renewable Diesel
Basis: Calculation
Calculation: [EMFAC category fuel combustion] * ([Fuel sales] / [EMFAC total fuel combustion]) * [Fraction of fuel mix]
