♦ Category: Energy

IPCC: 1A4c - Fuel Combustion Activities - Other Sectors - Agriculture/Forestry/Fishing/Fish Farms
Sector: Agriculture & Forestry : Ag Energy Use

♦ Activity: Fuel combustion - Gasoline

♦ Greenhouse gas: Nitrous oxide ( N2O )

► Year 1990 —

● Greenhouse gas emission estimate —

Amount: 3.65 tonnes of N2O Emitted (1,132 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Fuel combustion] * [Heat content] * [Fuel N2O emission]

● Activity level used in calculations —

Activity: Fuel combustion = 48,705,974 gal of Gasoline
Basis: Data
Reference: DATA NOT AVAILABLE -Value for this year is assumed to be equal to the average value for years 2001 to 2004.

● Parameters and Constants used in calculations —

Parameter: Fuel N2O emission = 6.000E-07 g / btu
