Terradot, an enhanced rock weathering carbon removal company, said it has agreed to acquire assets of Eion, a U.S.-based enhanced rock weathering company that pioneered olivine-based deployments and helped generate some of the first issued enhanced rock weathering credits.
The combination aims to unite Terradot’s measurement, reporting, and verification capabilities with Eion’s operating footprint and field execution, expanding the combined platform across the U.S. and Brazil.
Enhanced rock weathering accelerates a natural process that durably removes carbon dioxide from the atmosphere by applying crushed minerals, such as basalt or olivine, to farmland, where they react with CO₂ as they weather. Terradot positioned the acquisition as a step toward industrial-scale delivery as durable carbon markets mature and buyers favor platforms that can demonstrate repeatable operations supported by defensible measurement.
Terradot said Eion’s assets, intellectual property, project footprint, operating capabilities, and carbon removal contracts will be integrated into Terradot, along with Eion’s core team. The company said the integration is intended to share data, patents, tools, and operating learnings across the combined platform while keeping teams focused on program delivery, and framed the deal as establishing Terradot as a consolidator in enhanced rock weathering.
The agreement includes Eion’s contracts for more than 100,000 carbon removal credits. Terradot said that, together with its existing carbon removal contracts totaling more than 300,000 tonnes, including contracts with Google and Frontier, the combined company will represent one of the largest contracted enhanced rock weathering portfolios in the market.
Terradot said the acquisition diversifies its portfolio by adding olivine-based deployments in the U.S. alongside basalt-based deployments in Brazil. The company said this geography and feedstock mix can support a more resilient delivery profile across soils, supply chains, and growing seasons, and can enable faster learning through year-round field activity across hemispheres. Terradot also said the expanded footprint supports additional on-farm participation and creates demand for local services such as logistics, spreading, and field operations, with potential economic benefits for rural communities.
On the technical side, Terradot said it will integrate Eion’s deployment dataset, patent portfolio, and published measurement work into its measurement, reporting, and verification platform, which it described as built on rigorous measurement, conservative quantification, and transparent validation. The company said the combined foundation is intended to improve the defensibility of measurement approaches and support scaled delivery of high-quality carbon removal.
KEY QUOTES
“ERW is becoming a critical pathway for durable carbon removal, and the market is moving from pilots to industrialized programs built to deliver at scale. Integrating Eion’s olivine deployments into the Terradot platform pairs proven field execution with best-in-class science and expands a diversified portfolio across the U.S. and Brazil. The result is a more delivery-ready and more financeable platform that strengthens execution across our existing projects and gives long-term buyers greater confidence as we scale.”
James Kanoff, Chief Executive Officer, Terradot
“This combination strengthens Terradot’s financeability. A larger, diversified portfolio with an operating track record and high-integrity MRV improves bankability and expands access to long-term capital for project development and delivery.”
Rob Parker, Chief Financial Officer, Terradot
“Eion has focused on making ERW work in the field, with rigor and integrity. Joining Terradot continues Eion’s work and makes us more execution-ready from day one by bringing experienced operators, established field workflows, and farmer partnerships onto Terradot’s scaling platform. Together, we can move faster in deployment, raise the bar for credible ERW at scale, and expand opportunities for farmers and rural communities.”
Ana Pavlovic Hans, Chief Executive Officer, Eion
“Scaling durable carbon removal requires scientific integrity, measurement rigor, and strong real-world data. By bringing Eion’s operating learnings and technical contributions into the Terradot platform, we strengthen the foundation for the most defensible measurement approach in ERW and accelerate our path to scaled, high-quality delivery.”
Scott Fendorf, Chief Science Officer, Terradot
