ClassNK launches third-party certification service for individual green steel products

12 November 2024 – ClassNK has launched a third-party product certification service for individual green steel products. Under the service, ClassNK certifies each green steel product supplied by steel manufacturers using the mass balance approach*1, and affixes a certification logo*2 to its mill certificate. By improving reliability and making identification easier, the service ensures that users feel more secure when ordering and using green steel.

Certification service scheme for green steel

ClassNK has supported decarbonization efforts related to green steel through its certification services. Notable examples are conformity assessments for GHG emissions reductions during the manufacturing process and supply volumes of green steel allocated by the mass balance approach, as well as granting notations*3 that indicate the use of green steel in ships.

With the newly launched certification service, every green steel product supplied by steel manufacturers that have received ClassNK’s conformity assessments can now be certified as green steel. As these products undergo third-party certification, purchasers can order and use them with more confidence.

Once the product has been certified, a logo will be added to its mill certificate. As a result, the certificate is all that buyers need to confirm that the product is green steel.

Certification logo

This service applies not only to green steel products used in ships, but also to products used in various industries, such as automotive and construction.

In addition to this new service, ClassNK will continue to enhance its related certification services, thereby further contributing to decarbonization initiatives.

*1  The mass balance approach aggregates the environmental value of CO2 reductions from the entire manufacturing process and allocates it to specific steel products, which are then considered to have a lower CO2 emissions intensity.

*2  Certification logo

*3  Ships that meet specific requirements will be given the corresponding class notation.
