Deliveries under the contract commence this year, targeting the burial of waste wood in engineered underground chambers to prevent decomposition. By locking carbon away for centuries without energy-intensive capture processes, the project offers a cost-effective alternative to direct air capture. This single commitment accounts for roughly 4% of the 1.5 million tonnes of permanent removal delivered globally to date.

Senken CEO Adrian Wons noted that corporate net-zero targets are rapidly outpacing available verified capacity, creating a market gap that will persist for the next decade. For Carbonsate, the long-term offtake provides the financial certainty required to scale operations at their Namibian sites. The project operates under the Puro.earth standard, utilizing proprietary monitoring and verification systems to ensure high-integrity storage.
