♦ Category: Energy

IPCC: 1A3dii - Fuel Combustion Activities - Transport - Water-borne Navigation - Domestic Water-borne Navigation
Sector: Transportation : Water-borne : Interstate : Transit (CA waters)

♦ Activity: Fuel combustion - Residual fuel oil

♦ Greenhouse gas: Carbon dioxide ( CO2 )

► Year 1990 —

● Greenhouse gas emission estimate —

Amount: 145,944 tonnes of CO2 Emitted (145,944 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Fuel combustion] * [Heat content] * [Fuel CO2 emission]
