ClassNK has released a new document, entitled ‘What is the IMO’s Mid-term measures and how it works’, to promote understanding of the IMO’s mid-term measures.
The document explains the mid-term measures including calculation examples of contribution and timeline of action items for easy understanding. At the 83rd session of the IMO Marine Environment Protection Committee (MEPC 83) held in April 2025, draft amendments to Marpol Annex VI including the IMO’s mid-term measures for GHG reduction were approved. In response, the draft amendments will be considered for adoption at an extraordinary MEPC session in October 2025.
The mid-term measures consist of the following two regulations: GHG intensity regulation for fuels used (GFI regulation) and Promotion of decarbonization through the IMO Net-Zero Fund. A correct understanding of the regulations is seen by ClassNK as the first step toward responding appropriately. This document has been issued to support that effort.
ClassNK says it will continue to strive to support stakeholders in the maritime sector by providing information as part of the ‘ClassNK Transition Support Services.’
What is the IMO’s Mid-term measures and how it works is available from the ClassNK website.
