♦ Category: Energy

IPCC: 1A3aii - Fuel Combustion Activities - Transport - Civil Aviation - Domestic Aviation
Sector: Transportation : Aviation : Domestic Air transport : Intrastate

♦ Activity: Fuel combustion - Jet fuel

♦ Greenhouse gas: Carbon dioxide ( CO2 )

► Year 1990 —

● Greenhouse gas emission estimate —

Amount: 4,670,751 tonnes of CO2 Emitted (4,670,751 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Fuel combustion] * [Heat content] * [Fuel CO2 emission]

● Activity level used in calculations —

Activity: Fuel combustion = 486,372,695 gal of Jet fuel
Basis: Calculation
Calculation: [Total domestic fuel use] * [Intrastate miles travelled] / ([Intrastate miles travelled] + [Interstate miles travelled])
