There’s a growing focus on using green steel, which reduces GHG
emissions in the manufacturing process, in ships as part of efforts to cut GHG
emissions across the entire supply chain. To support these advanced
initiatives, ClassNK has released its ‘Environmental Guidelines,’ which set out
notations for ships with advanced environmental measures, such as the ‘a-EA
(GRS)’ notation to indicate the use of green steel in ship structures and other
components.
For ‘BRIGHT QUEEN,’ built by Higaki Shipbuilding Co., Ltd., ClassNK confirmed the use of JFE Steel
Corporation’s green steel ‘JGreeX’*1, for which ClassNK had
conducted third-party certification of GHG emissions reductions in the
manufacturing process, and granted the notation to the vessel.
In addition to granting notations for ships using green steel, ClassNK will
further contribute to decarbonization efforts through its certification
services, including those for GHG emissions reductions of green steel.
