♦ Category: Energy

IPCC: 1A1b - Fuel Combustion Activities - Energy Industries - Petroleum Refining
Sector: Industrial : Petroleum Refining

♦ Activity: Fuel combustion - Petroleum coke

♦ Greenhouse gas: Nitrous oxide ( N2O )

► Year 2000 —

● Greenhouse gas emission estimate —

Amount: 6.26 tonnes of N2O Emitted (1,941 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Fuel combustion] * [Heat content] * [Fuel N2O emission]
