1 Introduction

 In 1997 IMO adopted a resolution on CO2 emissions from shipsfootnote.

IMO Assembly further adopted resolution A.963(23) on IMO policies and practices related to the reduction of greenhouse gas emissions from ships, which requests the MEPC to develop a greenhouse gas emission index for ships, and guidelines for use of that index.

This document constitutes the Guidelines for the use of an Energy Efficiency Operational Indicator (EEOI) for ships. It sets out:

  • what the objectives of the IMO CO2 emissions indicator are;

  • how a ship’s CO2 performance should be measured; and

  • how the index could be used to promote low-emission shipping, in order to help limit the impact of shipping on global climate change.
