Shipping ManagementCII Improvement Plan: How to Improve a Ship CII Rating Without Slowing Trade
A CII Rating measures how efficiently a ship transports cargo or passengers in relation to its carbon emissions over an annual period. Introduced by the IMO under MARPOL Annex VI, it has become a key indicator of operational performance, environmental compliance, and commercial discipline across international shipping. For owners, operators, and shipowners, understanding CII Rating is essential because it affects how a vessel is managed, how fuel is used, and how efficiently trade can continue under tighter regulation.
