Method for determining TtW GHG emission factors

The TtW emissions are determined on the basis of the methodology contained in this Annex as provided in Equation (1) and Equation (2).

The TtW GHG emission factors (CO2eq,TtW,j ) default values are contained in Annex II.

In accordance with its monitoring plan referred to in Article 8 and upon assessment by the verifier, a company may use other methods, such as direct CO2eq measurement or laboratory testing, if they enhance the overall accuracy of the calculation, in application of Article 10(5).

Method for determining TtW fugitive and slipped emissions

Fugitive and slipped emissions are emissions caused by the amount of fuel that does not reach the combustion chamber of the combustion unit or that is not consumed by the fuel consumer unit because they are uncombusted, vented, or leaked from the system. For the purposes of this Regulation, fugitive and slipped emissions are taken into account as a percentage of the mass of the fuel used by the fuel consumer unit. The default values are contained in Annex II.

Methods for determining the reward factors linked to wind-assisted propulsion

Where wind-assisted propulsion is installed on board, a reward factor can be applied, determined as follows:

Reward factor for wind-assisted propulsion – WIND (fwind)

Formula

0,99

0,05

0,97

0,1

0,95

≥ 0,15

Where:

—

PWind is the available effective power of the wind-assisted propulsion systems and corresponds to feff * Peff as calculated in accordance with the 2021 guidance on treatment of innovative energy efficiency technologies for calculation and verification of the attained energy efficiency design index (EEDI) and energy efficiency existing ships index (EEXI) (MEPC.1/Circ.896);

—

PProp is the propulsion power of the ship and corresponds to PME as defined in the 2018 guidelines on the method of calculation of the attained EEDI for new ships (IMO resolution MEPC.364(79)) and the 2021 guidelines on the method of calculation of the attained EEXI (IMO resolution MEPC.333(76)). Where shaft motor(s) are installed, PProp = PME + PPTI(i),shaft.

The GHG intensity index of the ship is then calculated by multiplying the result of Equation (1) by the reward factor.
