Arbon Earth
Arbon Earth is a marine-based carbon dioxide removal company that cultivates fast-growing macroalgae on bamboo structures called OceanPods, then sinks the mature biomass to the deep seabed for long-term carbon storage. The company offers verified carbon removal subscriptions and one-off purchases, with an online calculator that estimates a company's CO₂ footprint based on employee count. Sequestered carbon is independently verified and certified through ONCRA, the Open Natural Carbon Removal Accounting Platform.

Problem
Companies and individuals seeking to achieve net-zero targets face a limited supply of high-quality, permanent carbon removal options. Many existing solutions rely on energy-intensive machinery or land-based approaches with uncertain long-term storage, making it difficult to find scalable, verifiable methods that can be trusted to deliver lasting climate impact.
Solution
Arbon Earth removes CO₂ from the atmosphere by cultivating fast-growing macroalgae on bamboo structures called OceanPods, which are deployed offshore. As the algae grow, they absorb CO₂ through photosynthesis, and once fully grown, the biomass is lowered to the deep seabed where the carbon is isolated for centuries to millennia. The company also deploys OceanBaskets near coastlines to enhance scalability. Sequestered CO₂ is verified and certified by ONCRA, an independent third-party verifier, giving customers confidence in the permanence of their carbon removal. Customers can purchase carbon removal through a subscription or one-off purchase, with an online calculator that estimates their footprint based on employee count or individual consumption.
Target Audience
Primary customers are corporations aiming to reach net-zero targets or strengthen their sustainability profile, as well as governments and individuals seeking verified climate action through carbon removal subscriptions.
Features
- OceanPods: bamboo and macroalgae structures deployed offshore that capture CO₂ as the algae grow, then sink the mature biomass to the deep seabed for long-term carbon storage
- OceanBaskets: complementary near-coast deployment method using bamboo and macroalgae to expand scalability of carbon removal operations
- Arbon Calculator: online tool that estimates a company's CO₂ footprint based on employee count or an individual's private consumption, then recommends a matching monthly subscription volume
- Third-party verification through ONCRA (Open Natural Carbon Removal Accounting Platform) to certify sequestered carbon tons
- Nature-based approach requiring no artificial air capture machinery, with OceanPods also serving as marine nurseries that support biodiversity
- Low-emission operations that leverage photosynthesis, with feasibility studies and tests conducted in Indonesia, Iceland, and the Caribbean
