GHG Emissions Management Tool from ClassNK

ClassNK has released ClassNK ZETA, a GHG emissions management tool to track accurate CO2 emissions and confirm and simulate CII ratings.

ClassNK has released “ClassNK ZETA (Zero Emission Transition Accelerator)”. It is a GHG emissions management tool to track accurate CO2 emissions and confirm and simulate CII ratings.


Eventually, the shift toward a zero-emission society has accelerated around the world. Hence, the time has come for the maritime industry to systematically plan, manage, and report the GHG emissions from shipping.

ClassNK has provided “ClassNK Zero Emission Transition Support Services” to support customers involved in the maritime transportation business make a smooth transition to zero-emission. Thus, planning and managing GHG emissions in their daily business operations.

The GHG emissions management tool, developed as part of the services to visualize CO2 emissions from ships. The subject development, links with the “ClassNK MRV Portal” and supports compliance with MRV schemes. For instance, IMO DCS and EU-MRV regulations. Users of MRV Portal can utilize the following four features without preparing additional data.

  • Vessel Monitoring: Displays CO2 emissions, CII rating, etc. of individual ships without delay. Users can also check the estimated annual CO2 emissions and CII ratings. This is based on the current operation status at any time and considers any necessary measures.
  • Fleet Monitoring: Displays CO2 emissions and CII ratings of the entire fleet for each company or team in charge, without delay. Allows to check the CO2 emissions of the fleet and the progress of the company’s overall CO2 reduction targets at any time.
  • Simulation: Simulates the changes in CO2 emissions and CII ratings for an individual ship or fleet that would be seen by slow steaming, installing energy-saving devices, or switching fuels. Various simulations enable users to consider measures for reducing CO2 emissions.
  • Periodical Report: Outputs CO2 emissions by ship, fleet, voyage, etc. In the future, it will also allow users to meet the reporting needs of various stakeholders. For example, financial institutions, cargo owners, and insurance companies.

As well as to ship management companies and other data holders, ClassNK ZETA is also available to shipowners and charterers, subject to data usage permission by the data holders. In the future, ClassNK will expand its functions for use by various stakeholders involved in maritime transportation, such as cargo owners and financial institutions, and will also work to enhance its functions in collaboration with external partners.
