Global Centre for Maritime Decarbonisation publishes LCA from Project CAPTURED

In Singapore, the Global Centre for Maritime Decarbonisation (GCMD) has published an LCA of the greenhouse gas (GHG) emissions from Project CAPTURED—the world’s first ship-to-ship offloading of onboard captured and liquefied CO2 (LCO2) with downstream utilisation, completed in June 2025. Verified by DNV, the LCA quantifies GHG emissions and savings across the pilot’s entire carbon value chain, tracing CO2 captured and liquefied on an ocean-going container vessel to ship-to-ship and ship-to-truck transfers, overland transport, and its utilisation at an industrial facility. There, the CO2 was used as a feedstock to recycle steel slag into post-carbonated slag (PCS) and produce precipitated calcium carbonate (PCC) through carbon mineralisation, a process in which captured CO2 is chemically converted into stable carbonates, fixing carbon long term.
