♦ Category: Energy

IPCC: 1A1ai - Fuel Combustion Activities - Energy Industries - Main Activity Electricity and Heat Production - Electricity Generation
Sector: Electricity Generation (Imports) : Specified Imports : PSW : Four Corners (NM)

♦ Activity: Fuel combustion - Coal

♦ Greenhouse gas: Nitrous oxide ( N2O )

► Year 1990 —

● Greenhouse gas emission estimate —

Amount: 77.40 tonnes of N2O Emitted (23,995 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Fuel combustion] * [Heat content] * [Fuel N2O emission]

● Activity level used in calculations —

Activity: Fuel combustion = 2,991,400 ton of Coal

● Greenhouse gas emitted per unit activity —

Amount: 25.9 g of N2O per ton of Coal
8,021 g (i.e. 8.02 kg) of CO2eq. per ton of Coal
