With regard to the Energy Efficiency Design Index (EEDI) required by the revised MARPOL ANNEX VI which entered into force on 1 January 2013, this is information that IACS Procedural Requirement No.38 (hereinafter, PR38) has been established to provide the unified procedures for calculation and verification of the EEDI.

1. Background
A Joint Industry Working Group on the EEDI (JWG/EEDI), formed by IACS and other industries such as shipowners, shipbuilders, research institutes, or similar industry based organizations, etc., developed "Industry Guidelines (first version)" to provide details and examples of calculating attained EEDI as well as support the method and role of the verifier in charge of conducting the survey and certification of EEDI in compliance with relevant IMO guidelines.
The IACS Council at its 66th meeting held in December 2012 has made a decision to convert the Industry Guidelines into IACS Procedural Requirement, and adopted as PR38 in May 2013.
Thus, Industry Guidelines are to be used as procedures to be followed by all IACS members.

2. Application
This PR38 applies to the ships for which the building contract is placed on or after 1 July 2013.

In the EEDI calculation and verification for the ships mentioned in paragraph 2 above, please make sure that it is required to follow the procedures in PR38 along with the relevant IMO guidelines.
