♦ Category: Energy

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

♦ Activity: Fuel combustion - Natural gas

♦ Greenhouse gas: Carbon dioxide ( CO2 )

► Year 1990 —

● Greenhouse gas emission estimate —

Amount: 330.14 tonnes of CO2 Emitted (330.14 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Fuel combustion] * [Heat content] * [Fuel CO2 emission]
