IMO MEPC 75: New GHG regulations for ships approved

Full news + PDF IMO news

EEXI overview

With the Greenhouse Gas Strategy towards 2050, the IMO has set the goal to reduce carbon intensity by 40% within the next decade up to 2030 and by 50% in total (70% intensity) up to 2050. The Greenhouse Gas Strategy was approved by the IMO in 2018. The reduction rates are related to the baseline of 2008. Short-term, mid-term and long-term measures are distinguished to achieve the goal.

Short-term measures are meant to be set into force by 2023. Different measures were considered and widely discussed, for example the introduction of a speed limit. With the experience of market-driven slow steaming for nearly one decade, this measure is promising with regards to its potential to save CO2 emissions.

Introduction of the Energy Efficiency Existing Ship Index (EEXI)

During MEPC 75 in November 2020, the IMO approved amendments to MARPOL Annex VI, introducing an Energy Efficiency Design Index for existing ships (EEXI). Subject to adoption at MEPC 76 in June 2021, the requirements will enter into force in 2023. The EEXI will be applicable for all vessels above 400 GT falling under MARPOL Annex VI. Guidelines on calculations, surveys and verification of the EEXI will follow and be finalized at MEPC 76. Nevertheless, as the EEXI is the extension for existing ships of the newbuilding related EEDI, most procedures will be the same as for the EEDI, with some adaptations regarding limited access to design data. Already today, DNV GL's maritime advisory offers EEXI-related services based on IMO submissions which serve as the basis for the future calculation guideline.
