Terradot Acquires Eion to Form Leading Global Enhanced Rock Weathering Carbon Removal Platform

Terradot, an enhanced rock weathering (ERW) carbon removal company, today announced it has agreed to acquire assets of Eion, a U.S.-based ERW company known for pioneering olivine-based deployments and an early track record of technical innovation, including some of the first issued ERW credits.

Enhanced rock weathering accelerates a natural process to durably remove carbon dioxide from the atmosphere. Crushed minerals like basalt or olivine are applied to farms and ranches, where they react with CO₂ as they weather. As durable carbon markets grow, ERW is emerging as a highly scalable climate solution that can become a major source of long-term carbon removal.

This acquisition strengthens Terradot’s position as the category-leading ERW platform and brings Eion’s key assets, intellectual property, project footprint, operating capabilities, and carbon removal contracts into Terradot, along with its core team and operational expertise. Eion will be integrated in a way that strengthens both existing programs by sharing data, patents, tools, and operating learnings across the combined platform while keeping teams focused on delivery.

“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,” said James Kanoff, CEO of Terradot. “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.”

For customers, the acquisition is designed to increase delivery certainty by improving financeability, accelerating shared learnings across projects, and diversifying risk across geographies and feedstocks. “This combination strengthens Terradot’s financeability,” said Rob Parker, Chief Financial Officer of Terradot. “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.”

Eion’s contracts for more than 100,000 carbon removal credits are included in the agreement. Combined with Terradot’s carbon removal contracts totaling more than 300,000 tonnes with companies such as Google and Frontier, the combined platform represents one of the largest contracted ERW portfolios in the market.

“Eion has focused on making ERW work in the field, with rigor and integrity,” said Ana Pavlovic Hans, CEO of Eion. “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.”

ERW Is Entering a New Phase: From Pilots to Industrial Delivery

Demand for enhanced rock weathering is increasing. Public disclosures tracked by CDR.fyi show multi-year ERW offtake agreements now commonly measured in the tens of thousands of tonnes, with some purchases surpassing 100,000 tonnes.

With Eion, Terradot expands its portfolio to include olivine-based deployments in the U.S. alongside basalt-based deployments in Brazil. This diversified portfolio supports more resilient delivery across soils, supply chains, and growing seasons.

ERW projects are built in partnership with farmers and local operators. By expanding Terradot’s footprint across the U.S. and Brazil, the combined platform supports more on-farm participation and creates durable demand for local services like logistics, spreading, and field operations.

Combining Best-in-Class Science With Proven Field Execution

Terradot’s MRV platform is built on rigorous measurement, conservative quantification, and transparent validation. As part of this transaction, Terradot will integrate Eion’s deployment dataset, patent portfolio, and published MRV work into that platform.

“Scaling durable carbon removal requires scientific integrity and strong real-world data,” said Scott Fendorf, Chief Science Officer of Terradot. “By bringing Eion’s operating learnings and technical contributions into the Terradot platform, we strengthen the foundation for defensible measurement approaches in ERW and accelerate our path to scaled delivery.”
