( The International Convention for the Prevention of Pollution from Ships (MARPOL) is set to undergo significant amendments starting 01 May 2024. These updates aim to further enhance maritime environmental protection, reflecting the global maritime community's ongoing commitment to sustainable shipping practices.

The new provisions will impact various aspects of maritime operations, from the handling and disposal of ship-generated waste to stricter controls on emissions. The upcoming changes are crucial for ship owners, operators, and the broader maritime industry as they align with international efforts to combat environmental pollution and promote a greener future.

This introduction to the changes in MARPOL is intended to provide stakeholders with a preliminary understanding of the modifications and their potential implications on maritime activities.
