Regulation 25 - Required EEXI

 1 For:

  • .1 each ship; and

  • .2 each ship which has undergone a major conversion

which falls into one of the categories in regulations 2.2.5, 2.2.7, 2.2.9, 2.2.11, 2.2.14 to 2.2.16, 2.2.22, and 2.2.26 to 2.2.29 and to which this chapter is applicable, the attained EEXI shall be as follows:

Attained EEXI ≤ Required EEXI =(1−) · EEDI reference line value

where Y is the reduction factor specified in Table 3 for the required EEXI compared to the EEDI reference line.

10,000 and above but less than 20,000 DWT 0-20*
Gas carrier 15,000 DWT and above 30
10,000 and above but less than 15,000 DWT 20
2,000 and above but less than 10,000 DWT 0-20*

Containership 200,000 DWT and above 50
120,000 and above but less than 200,000 DWT 45
80,000 and above but less than 120,000 DWT 35
40,000 and above but less than 80,000 DWT 30
15,000 and above but less than 40,000 DWT 20
10,000 and above but less than 15,000 DWT 0-20*
General cargo ship 15,000 DWT and above 30
3,000 and above but less than 15,000 DWT 0-30*
Refrigerated cargo carrier 5,000 DWT and above 15
3,000 and above but less than 5,000 DWT 0-15*
Combination carrier 20,000 DWT and above 20
4,000 and above but less than 20,000 DWT 0-20*
LNG carrier 10,000 DWT and above 30
Ro-ro cargo ship (vehicle carrier) 10,000 DWT and above 15
Ro-ro cargo ship 2,000 DWT and above 5
1,000 and above but less than 2,000 DWT 0-5*
Ro-ro passenger ship 1,000 DWT and above 5
250 and above but less than 1,000 DWT 0-5*
Cruise passenger ship having non-conventional propulsion 85,000 GT and above 30
25,000 and above but less than 85,000 GT 0-30*
  • * Reduction factor to be linearly interpolated between the two values dependent upon ship size. The lower value of the reduction factor is to be applied to the smaller ship size.

 2 The EEDI reference line values shall be calculated in accordance with regulations 24.3 and 24.4 of this Annex. For ro-ro cargo ships and ro-ro passenger ships, the reference line value to be used from phase 2 and thereafter under regulation 24.3 of this Annex shall be referred to.

 3 A review shall be completed by 1 January 2026 by the Organization to assess the effectiveness of this regulation taking into account any guidelines developed by the Organization. If, based on the review, the Parties decide to adopt amendments to this regulation, such amendments shall be adopted and brought into force in accordance with the provisions of article 16 of the present Convention.
