TSUNEISHI SHIPBUILDING Co., Ltd. (HQ: 1083 Tsuneishi, Numakuma-cho, Fukuyama, Hiroshima, Japan; Representative Director, President, and Chief Executive Officer: Sachio Okumura) announced to have reached an agreement with JFE Steel Corporation (HQ: 2-2-3 uchisaiwaicho, Chiyoda-ku, Tokyo 100-0011, Japan; President and CEO: Yoshihisa Kitano) to adopt JGreeX™※1 to its vessel, among the first in the shipbuilding industry. JGreeX™ is the trademark for green steel produced by JFE Steel Corporation. Manufactured with highly advanced steelmaking technology whereby the process results in significantly less CO2 emissions than conventional steel products, JGreeX™ is expected to be available starting in September of 2023.

JGreeX™ is steel products with significantly reduced amount of CO2 emissions in the process of steel making by applying “the mass balance approach”※2 to allocate the CO2 emissions to the specific products through the technology to reduce CO2 emissions by JFE. An independent organization will perform third-party certifications to ensure transparency and reliability of JGreeX™ products and the respective output of their CO2 emissions-reduction levels.

TSUNEISHI SHIPBUILDING stands to achieve a 100% reduction in CO2 emissions ascribed to the production of steel plates, by instead using JGreeX™ products for all steel plate requirements in the construction of one hydrogen dual-fuel tug. The newbuild vessel order has been placed by the group’s shipping arm, KAMBARA KISEN Co., Ltd., and is expected to be operated by KAMBARA TUG AND MARINE SERVICE Co., Ltd.

TSUNEISHI SHIPBUILDING is committed in reducing carbon footprint impact to our environment by producing eco-ships that incorporate the use of green steel in their construction and hydrogen-powered combustion engines for their operation.

※1 JGreeX™：
The trademark for green steel produced by JFE Steel Corporation

※2 the Mass Balance Approach：
Under this approach, the environmental values of CO2 emissions reductions across entire manufacturing processes will be assigned to specific products considered to have low CO2 emissions intensity, complying with the guidelines by the Japan Iron and Steel Federation (JISF) on the method to calculate CO2 emissions intensity of green steel upon the application of the mass balance approach in the production process.
