♦ Category: Energy

IPCC: 1A4a - Fuel Combustion Activities - Other Sectors - Commercial/Institutional
Sector: Commercial : Retail & Wholesale : Refrigerated Warehousing

♦ Activity: Fuel combustion - Natural gas

♦ Greenhouse gas: Nitrous oxide ( N2O )

► Year 1990 —

● Greenhouse gas emission estimate —

Amount: 0.149 tonne of N2O Emitted (46.13 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Fuel combustion] * [Heat content] * [Fuel N2O emission]

● Activity level used in calculations —

Activity: Fuel combustion = 1,441,342,462 scf of Natural gas
Basis: Data
Reference: DATA NOT AVAILABLE - Value for this year is assumed to be equal to the average value for the latest 5 years with available data.

● Parameters and Constants used in calculations —

Parameter: Fuel N2O emission = 1.000E-07 g / btu
