Abstract

 

The article provides information on the amendments to Annex VI of the MARPOL Convention adopted at the 76th session of the IMO Marine Environment Protection Committee (MEPC), regulating the application of two new energy efficiency criteria: Energy Efficiency Index for Existing Ships (EEXI) and operational Carbon Intensity Indicator (CII). These criteria become mandatory from 01.01.2023 for existing ships performing transport work. General principles have been outlined for the development of energy efficiency criteria for sea-going ships as well as the division of energy efficiency criteria into structural and operational. The content of the new MARPOL requirements and recommendatory IMO Guidelines on calculations, survey and certification developed for uniform implementation of the requirements, have been briefly described, general assessment has been given with regard to the approach used and an algorithm for shipowners' actions to meet the new energy efficiency criteria has been proposed. Shortages of new criteria have also been mentioned, in particular, the fact that energy consumption not related to transport work has not been not accounted for.

 

Keywords: greenhouse gas emissions, ship energy efficiency, energy efficiency criteria, carbon intensity.
