ClassNK releases new features for GHG Emissions Management Tool "ClassNK ZETA" - supporting preparation for EU-ETS and BIMCO CII Clause -

4 January 2024

ClassNK has released new features for its GHG Emissions Management Tool, "ClassNK ZETA (Zero Emission Transition Accelerator)".

ClassNK ZETA is a tool for visualizing GHG emissions and CII ratings of ships and is used for over 5,000 ships. Based on data submitted to "ClassNK MRV Portal", a system for fuel consumption reporting in compliance with regulations such as IMO-DCS and EU-MRV, ClassNK ZETA provides accurate current status and simulation for reducing GHG emissions from ships and supports response to various emission reduction requirements. The following two features are newly released this time.

● EU-ETS Management
This feature displays GHG emissions for the entire fleet and individual ships, which are subject to the EU-ETS*1, and manages the emission allowances held by the company. It visualizes the emissions under the EU-ETS, enabling consideration of necessary measures such as purchasing emission allowances.

● BIMCO CII Clause Vessel Monitoring
In relation to CII rating target agreed between a shipowner and a charterer based on BIMCO's CII operations clauses for time charter parties*2, this feature allows real-time monitoring of attained CII and simulates changes by ship speed. It is useful for planning operations to achieve the agreed CII rating target.

Further, ClassNK plans to add functions for preparation for the FuelEU Maritime*3 regulation, which will be introduced for EU-related voyages from 2025.

ClassNK will continue to strive to enhance tools to support GHG emissions management such as ClassNK ZETA. Detailed information and an application form for ClassNK ZETA are available on the following page.

*2 Clause for time chartering contracts that correspond to the CII rating requirement issued by BIMCO (Baltic and International Maritime Council). It stipulates that upon agreeing to a CII rating target for each year between shipowner and time charterer, the charterer should optimize fuel selection and ship allocation to achieve the target.
