Overview  Draft new mandatory regulations to cut the carbon intensity of existing ships were approved on November 20, 2020 by the International Maritime Organization (IMO) Marine Environment Protection Committee (MEPC). In essence, they will require the world’s existing fleet to match at least the efficiency standards of newbuildings. These draft amendments will be circulated among IMO member states in view of their adoption in June 2021 (MEPC 76) with the expectation to enter into force by 2023.These are deemed to be in line with the ambition of the 2018-adopted initial IMO Green House Gas (GHG) Strategy to reduce carbon intensity of international shipping by 40% by 2030, compared to 2008.Proposed amendments to the MARPOL convention would require ships to combine a technical and an operational approach to reduce their carbon intensity.The technical requirement to reduce carbon intensity is based on a new Energy Efficiency Existing Ship Index (EEXI) whose standards will be largely equivalent to the current Energy Efficiency Design Index (EEDI) for newbuild ships.The operational carbon intensity reduction requirements are based on a new operational Carbon Intensity Indicator (CII) rating ships for fuel efficiency between A and E, with ships rated D and below falling under the minimum standard. This dual approach aims to address both technical (how the ship is retrofitted and equipped) and operational measures (how the ship operates).Finally, there is a mandatory Ship Energy Efficiency Management Plan (SEEMP) for all ships. The SEEMP provides for ship operators to have in place a plan to improve energy efficiency through a variety of ship specific measures. Compliance with the SEEMP will be monitored.Roel Hoenders, Acting Head of Air Pollution and Energy Efficiency of IMO’s Marine Environment Division will take us through all the details of the recently agreed measures to reduce carbon emission by 2030.After a half hour slide presentation, there will be a Q&A session for another half hour plus, where participants can submit their questions live.  Speaker Roel Henders, Acting Head of Air Pollution and Energy Efficiency, Marine Environment Division, International Maritime Organization (IMO)
