IMO study on the effectiveness and implementation of the ISM Code
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 attained Energy Efficiency Existing Ship Index (EEXI) is required to be calculated for every ship. This indicates the energy efficiency of the ship compared to a baseline. Ships are required to meet a specific required Energy Efficiency Existing Ship Index (EEXI), which is based on a required reduction factor (expressed as a percentage relative to the EEDI baseline).
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 CO2Â emissions.
