ClassNK Zero-Emission Transition Support Services

The shift toward a zero-emission society has accelerated in a variety of fields, with governments making their GHG targets more ambitious and sustainable finance gaining more attention. Likewise, the time has come for the maritime industry to systematically manage the GHG emissions from shipping, as represented by the introduction of a GHG emissions evaluation framework into international shipping.

ClassNK provides Zero-Emission Transition Support Services, a comprehensive menu of services to support customers in dealing with the various challenges they may encounter when managing GHG emissions in pursuit of zero-emission shipping.

GHG Emissions Management Systems Development & Certification

Certification of management system for GHG emissions from ships

ClassNK encourages its customers through certification of their voluntary efforts to set a clear target for GHG reductions and to develop an appropriate management system for its achievement. This certification is expected to add further values to the ingenuity in our customers’ future shipping business.

This certification is provided as a part of Innovation Endorsement (IE), a framework to support the customers’ innovative initiatives in tackling various challenges including environmental issues that require innovative solutions. For the details of IE, please refer to the following:

GHG Emissions Management Tool

ClassNK MRV Portal

ClassNK released “ClassNK MRV Portal” in 2017, a software to assist the development of emission reports required by the IMO-DCS/EU MRV. ClassNK MRV Portal is now under improvement to install a continuous monitoring function for CII, which would become effective from 2023, so that our customers can always check their fleets’ CII ratings of any given point in time. This improvement is expected to complete within 2021.

For the details of ClassNK MRV Portal, please refer to the following:

ClassNK ZETA (Zero Emission Transition Accelerator)

ClassNK is newly developing ClassNK ZETA (Zero Emission Transition Accelerator), a one-stop tool for data utilization linked with ClassNK MRV Portal. With ClassNK ZETA, users can monitor the CO2 emissions at an individual ship/fleet level. It is also beneficial for the Signatories of other global frameworks, such as the Poseidon Principles and the Sea Cargo Charter. As an integrated data platform, ClassNK ZETA will cater the needs of a wide range of customers including shipowners, charterers, financial institutions, and cargo owners. ClassNK ZETA is expected to be in operation within 2021.

GHG Emissions Verification & Assessment

EEDI/EEXI/DCS/CII (as statutory services) and EU-MRV

In addition to the existing verification services for EEDI, IMO-DCS and EU-MRV, ClassNK released simple assessment tools for EEXI and CII on its website for its customers’ smooth response to EEXI requirements/CII that will enter into force from 2023. For the details of each service, please refer to the following:

Support for Poseidon Principles and Sea Cargo Charter

Some global frameworks have been recently launched to support the decarbonization of international shipping; the Poseidon Principles were established in 2019 to support CO2 reductions from the standpoint of financial institutions, and the Sea Cargo Charter in 2020 from the standpoint of charterers. ClassNK conducts assessment of CO2 reductions as an independent third party to assist customers’ CO2 emissions calculations and to evaluate their CO2 reductions efforts. For the details of such services, please refer to the following:

Evaluation for the achievement of carbon neutrality

As climate change is gaining more and more attention on a global scale, companies are increasingly setting their ambitions to achieve carbon neutrality by 2050. Customers may also be aiming to achieve carbon neutrality by 2050 for their fleet. For such customers, ClassNK, as an independent third party, conducts evaluation on how much the CO2 emissions from the customer’s shipping business are aligned with the pathway toward their goals of carbon neutrality.

ClassNK responds to various inquiries and provides information on biofuels so as to facilitate the understanding of biofuel usage on ships. For the details of biofuels, please refer to the following.


Support for alternative fuels introduction

ClassNK issued “Guidelines for Ships Using Alternative Fuels (Edition 1.1)” as a part of its services for GHG emissions reduction support. This is an update to “Guidelines for Ships Using Low-Flashpoint Fuels (Methyl/Ethyl/Alcohol/LPG)” to newly include the requirements for ammonia-fueled vessels and to comprehensively cover the safety requirements for ships using these alternative fuels. Furthermore, the conventional Notation of “LNG Ready” has been updated to “Alternative Fuel Ready” and the relevant requirements have been organized for the ships with designs for the future usage of alternative fuels and/or with partial installation of relevant equipment.

The guidelines are available to download via ClassNK “My Page” service, which can be accessed with free registration. To register for the “My Page” service, please click on the “My Page Login” button on the home page.
