PI007 | Emitted mass of CO2 V4.0

Performance Indicator

The total mass of emitted CO2 in laden and ballast condition, calculated on the basis of fuel consumption.


Definition

The mass of CO2 emitted by the vessel is calculated by multiplying given fuel type consumption expressed in metric tons by a respective non-dimensional conversion factor provided below.


The total mass of CO2 emitted by the vessel is calculated by adding masses of CO2 emitted by the vessel burning all, different types of fuel.

Respective fuel consumptions shall be calculated only for voyages completed during given quarter in order to be compared to the Transport Work (PI064). This means that an inaccuracy is acceptable with respect to the definition of the quarter.

The emitted mass of CO2 must be calculated per fuel type used during the quarter and then be aggregated to report the total mass of emitted CO2 per ship.

Example

Bunker consumption:
2060.00 metric tons Heavy Fuel Oil
Emitted mass CO2 = 2060.00 mts * 3.114 = 6414.84 mts
182.00 metric tons of Diesel
Emitted mass CO2 = 182.00 mts * 3.206 = 583.49 mts
Total mass of emitted CO2 = 6414.84 mts + 583.49 mts = 6998.33 mts
