NYK Buys Carbon Removal Credits From Graphyte’s Large Scale Biomass Project

NYK will purchase carbon dioxide removal credits from Graphyte’s Loblolly project in Arkansas, which uses biomass residues from agriculture, forestry, and wood processing.
The credits will support NYK’s net-zero strategy as the shipping sector manages residual emissions that remain hard to eliminate.
The deal adds momentum to durable carbon removal markets, where independent verification and long-term storage are becoming critical for corporate climate claims.

NYK Turns To Durable Carbon Removal

NYK has signed an agreement to purchase carbon dioxide removal credits from Graphyte, a U.S.-based carbon-removal startup developing one of the world’s large-scale biomass-based removal projects.

The credits will come from Graphyte’s Loblolly project in Arkansas. The facility uses Graphyte’s carbon-casting technology. It processes biomass residues from agriculture, forestry, and wood processing.

For NYK, the deal supports a wider emissions strategy. The company is targeting emissions that cannot be fully cut through efficiency or Shipping remains difficult to decarbonize. Vessels have long asset lives, global routes, fuel gaps, and limited scalable zero-emission options.

The company said it is working to cut greenhouse gas emissions, including CO₂. It is moving toward net zero. That strategy includes improving energy efficiency. It also includes shifting from fossil fuels to LNG, ammonia, and methanol.

But NYK acknowledged that some residual emissions in shipping remain unavoidable. By using carbon dioxide removal credits, the company aims to offset those emissions and support its net-zero CO₂ pathway.

Graphyte’s Carbon-Casting Model

Graphyte’s Loblolly project is currently underway in Arkansas. Its process focuses on biomass residues that already contain carbon absorbed from the atmosphere during plant growth.

Instead of allowing those residues to decompose or release carbon back into the atmosphere, Graphyte dries and compresses them into dense carbon blocks. These blocks are then stored underground in a stable form designed for long-term sequestration.

The model is gaining attention because it targets durability, one of the most important tests for corporate carbon removal procurement. Buyers are increasingly looking beyond short-term offsets and toward removals that can be measured, independently verified, and stored for extended periods.

NYK said the credits generated by the Loblolly project are certified through measurement, reporting, and verification conducted by independent third parties. That structure is intended to provide transparency and reliability for the credits.

For investors and corporate buyers, this point matters. Carbon markets have faced growing scrutiny over credit quality, additionality, permanence, and accounting. Durable carbon removal credits remain more expensive than traditional offsets, but they are also becoming more relevant for companies with credible net-zero strategies.

Shipping’s Residual Emissions Challenge

The agreement reflects a wider shift in climate strategy across hard-to-abate sectors. Companies are being pushed to cut emissions directly first, then use high-quality removals only for the balance that cannot be eliminated.

For shipping groups, that balance is complex. Fuel changes require new vessels, ports, safety systems, supply chains, and customer acceptance. Ammonia and methanol are gaining traction, but commercial scale remains uneven. LNG can reduce certain emissions compared with conventional fuels, yet it does not remove the need for deeper decarbonization over time.

This is where carbon dioxide removal enters the picture. It is not a substitute for operational decarbonization. It is a tool for dealing with residual emissions where direct abatement is technically or economically limited.

NYK said that, in line with its position paper on CDR credits, the group will continue to promote initiatives that contribute to reducing greenhouse gas emissions through various credits. The company also said it will work with customers to help realize a decarbonized society.

Why It Matters For Corporate Climate Strategy

The NYK-Graphyte agreement adds another signal that large industrial and transport companies are beginning to build carbon removal into long-term transition planning.

For C-suite leaders, the key issue is not whether credits are available. It is whether they are credible enough to withstand investor, customer, and regulatory scrutiny. That puts the focus on independent verification, durability, transparent accounting, and clear limits on how credits are used.

The agreement also highlights the growing connection between carbon removal procurement and sector-specific transition risk. Shipping companies face pressure from regulators, cargo owners, lenders, and insurers to show how they will align with global climate goals. Carbon removal may help close part of that gap, but only when paired with clear emissions reduction plans.

For Graphyte, NYK’s purchase adds demand from a major global shipping player. For NYK, the deal strengthens its climate toolkit as the maritime industry navigates a difficult shift from fossil fuels to lower-carbon systems.

The broader significance is clear. Durable carbon removal is moving from pilot-stage climate ambition into corporate procurement. In hard-to-abate sectors, that shift could shape how companies manage the final stretch toward net zero.
