Maritime Strategies International (MSI) says there is a “pressing” need to adjust the ship energy efficiency calculations used by banks under the Poseidon Principles.

The shipping research company has calculated how 21,000 vessels would rate under the Poseidon Principles’ Annual Efficiency Ratio (AER) trajectory, which is based on the International Maritime Organization’s decarbonisation targets.

The 27 signatories to the Poseidon Principles are using the trajectory to inform their ship investment decisions.
