NYK partners with Graphyte to purchase carbon removal credits for shipping emissions

Nippon Yusen Kabushiki Kaisha (NYK) has signed an agreement with the United States-based carbon removal start-up Graphyte, Inc. to purchase Carbon Dioxide Removal (CDR) credits. The credits will be generated by Graphyte’s large-scale “Loblolly” carbon removal project based in Arkansas.

The agreement forms part of the shipping group’s broader strategy to neutralise residual greenhouse gas emissions that cannot be eliminated through operational efficiencies alone.

The Loblolly project utilises a proprietary process known as carbon-casting. This technique involves drying and compressing biomass residues sourced from local agriculture, forestry, and wood processing industries.

By converting the carbon contained within these waste materials into a stable solid form, the process prevents decomposition. The biomass blocks are subsequently stored in secure underground repositories for long-term sequestration.

The CDR credits generated by this operation are certified through an independent third-party system of measurement, reporting, and verification to maintain transparency and reliability.
