(c) Carbon Dioxide Emission Factors for Transportation Fuels
The default carbon dioxide emission factors in Table 7 are provided for use with section 95125(i) of the regulation. These factors may only be used for vehicular emissions and should not be applied to stationary combustion sources.
Table 7. Carbon Dioxide Emission Factors for Transportation Fuels
CA Low Sulfur Diesel
CA Reformulated gasoline, 5.7% ethanol
Non-CA Diesel/Diesel No.2
Fischer Tropsch Diesel
Jet Fuel, Kerosene (Jet A or A-1)
Jet Fuel, Naphtha (Jet B)
Liquefied Natural Gas (LNG)
Liquefied Petroleum Gas (LPG)
Motor Gasoline (Non CA and off-road)
Fuels With Other Units Of Measure
Natural Gas (CNG) per therm
Natural Gas (CNG) per gasoline gallon equivalent
Hydrogen per kg
Note: Emission factors are based on complete combustion and high heating value (HHV).

Methanol emission factor is calculated from the properties of the pure compounds; the fraction oxidized is assumed to be the same as for other liquid fuel.
