♦ Category: Energy

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

♦ Activity: Electricity generation - Imported electricity

♦ Greenhouse gas: Nitrous oxide ( N2O )

► Year 1990 —

● Greenhouse gas emission estimate —

Amount: 362.30 tonnes of N2O Emitted (112,314 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Electricity Generation] * [Heat content] * [Fuel N2O emission]
