Annex – Guidelines for Voluntary Use of the Ship Efficiency Operational Indicator (EEOI)

  1 The Conference of Parties to the International Convention for the Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978 relating thereto, held from 15 to 26 September 1997 in conjunction with the Marine Environment Protection Committee’s fortieth session, adopted Conference resolution 8, on CO2 emissions from ships.

  2 IMO Assembly resolution A.963(23) on IMO policies and practices related to the reduction of greenhouse gas emissions from ships urged the Marine Environment Protection Committee (MEPC) to identify and develop the mechanism or mechanisms needed to achieve the limitation or reduction of Greenhouse Gas (GHG) emissions from international shipping and, in doing so, to give priority to the establishment of a GHG baseline; and the development of a methodology to describe the GHG efficiency of a ship in terms of GHG emission indicator for that ship.

  3 As urged by the Assembly, MEPC 53 approved Interim Guidelines for Voluntary Ship CO2 Emission Index for Use in Trials.

  4 These Guidelines can be used to establish a consistent approach for voluntary use of an EEOI, which will assist shipowners, ship operators and parties concerned in the evaluation of the performance of their fleet with regard to CO2 emissions. As the amount of CO2 emitted from a ship is directly related to the consumption of bunker fuel oil, the EEOI can also provide useful information on a ship’s performance with regard to fuel efficiency.

  5 These Guidelines may be updated periodically, to take account of:

  • - Operational experiences from use of the indicator for different ship types, as reported to MEPC by industry organizations and Administrations; and

  • - Any other relevant developments.

  6 Industry organizations and interested Administrations are invited to promote the use of the attached Guidelines or equivalent approaches and their incorporation in company and ship environmental management plans. In addition, they are invited to report their experience in applying the EEOI concept back to MEPC.

  7 In addition to these Guidelines, due account should be taken of the pertinent clauses within the ISM Code in voluntary basis along with reference to relevant industry guidance on the management and reduction of CO2 emissions.
