The 77th session of the IMO Marine Environment Protection Committee (MEPC 77) took place on 22-26 November 2021. Following the various declarations on climate change at COP26, expectations were high. Here, we provide an overview of some of the key discussions and decisions of the meeting. Short term GHG reduction measuresCorrection factors for certain ship types and operating profiles and voyages will continue to be developed. Guidelines for the operational measure ‘Ship energy efficiency management plan’ (SEEMP) have been developed and are expected to be adopted at MEPC 78 in 2022.Mid-to-long term GHG reduction measuresCOP 26 and the Paris Agreement have called for greater ambition to aim for net zero by 2050. Consideration was given to the introduction of mid-term measures and subsequent revision of the IMO strategy. This will be further discussed at Intersessional Working Group ISWG-GHG-12. The outcome of ISWG–GHG–9 and 10, paves the way in furthering the use of low and zero carbon fuels as well as market-based measures (e.g. a global GHG levy).Proposals for the International Maritime R&D Board (IMRB) and Fund (IMRF) were revised and to be considered at ISWG-GHG-12. A review of the life cycle analysis (LCA) is at an early stage, with concerns raised over the IMO’s ability to oversee well-to-tank emissionsFind out moreFor more details on this and the wider impact of MEPC 77, please refer to attached ABS brief – Click Here Visit our Decarbonisation in shipping page here.
