♦ Category: Energy

IPCC: 1A3di - Fuel Combustion Activities - Transport - Water-borne Navigation - International Water-borne Navigation (International Bunkers)
Sector: Transportation : Water-borne : International : Transit (CA waters)

♦ Activity: Fuel combustion - Residual fuel oil

♦ Greenhouse gas: Carbon dioxide ( CO2 )

► Year 2000 —

● Greenhouse gas emission estimate —

Amount: 421,385 tonnes of CO2 Emitted (421,385 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Fuel combustion] * [Heat content] * [Fuel CO2 emission]
