Amendments to MARPOL Annex VI, Chapter 4 Entering in to Force November 1, 2022

​The International Maritime Organization adopted an initial strategy on the reduction of GHG emissions from ships in 2018.  This initial strategy is the first milestone set out in the IMO Roadmap for developing a comprehensive strategy for the reduction of GHG emissions from ships.  Consistent with this initial strategy, IMO adopted Chapter 4 of MARPOL Annex VI.  Important amendments to Chapter 4 of MARPOL Annex VI, concerning energy efficiency of existing ships and carbon intensity of international shipping, were most recently adopted and will enter into force on November 1st, 2022.   These amendments focus on goal-based (also known as “performance-based”) technical and operational measures to reduce the operational carbon intensity of certain international shipping vessels.   The full text of MARPOL Annex VI, Chapter 4, can be found in Resolution MEPC.328(76), which can be found at https://wwwcdn.imo.org/localresources/en/OurWork/Environment/Documents/Air%20pollution/MEPC.328(76).pdf.
