Enhanced rock weathering (ERW) startup Terradot has acquired the assets of carbon removal peer Eion, in a deal aimed at strengthening Terradot’s delivery capacity as ERW transitions from pilot-scale deployments to industrialized climate solutions. The acquisition reflects growing momentum behind ERW as a scalable pathway for durable, long-term carbon removal.

Building a More Resilient ERW Deployment Footprint

Founded in 2022, Terradot focuses on accelerating the natural rock weathering process by crushing basalt and spreading it over farmland, allowing CO₂ absorbed by rainwater to be permanently stored in rock while also improving soil health. Through the acquisition, Terradot adds olivine-based ERW operations in the United States to its existing basalt-based deployments in Brazil, creating a more diversified operating profile across geographies, soil types, growing seasons, and supply chains.

From Pilot Projects to Industrial-Scale Execution

Terradot’s leadership framed the acquisition as a step toward greater execution readiness and financial scalability. According to CEO James Kanoff, integrating Eion’s olivine deployments with Terradot’s scientific and operational platform strengthens delivery reliability and increases confidence for long-term carbon removal buyers. The combined platform is positioned to support larger, more standardized ERW programs as demand for high-integrity carbon removal accelerates.

Strengthening Measurement and On-Farm Participation

Eion brings patented measurement, reporting, and verification (MRV) capabilities designed specifically for ERW-based carbon dioxide removal, along with established partnerships with farmers and local operators. The combined platform is expected to expand farmer participation while supporting local service demand, including logistics, material spreading, and field operations. This integration is intended to improve both traceability and scalability across ERW projects.

A Growing Contracted Carbon Removal Portfolio

The acquisition includes Eion’s contracts covering more than 100,000 carbon removal credits. When combined with Terradot’s existing contracted volumes of over 300,000 tons with buyers including Microsoft and Frontier, the merged platform represents one of the largest ERW-based contracted carbon removal portfolios globally.

Positioning ERW for Market Maturity

Eion CEO Ana Pavlovic Hans said the transaction accelerates deployment by pairing Eion’s operational experience and farmer relationships with Terradot’s scaling infrastructure. Together, the companies aim to raise standards for credible ERW deployment at scale while expanding economic opportunities for farmers and rural communities.

As voluntary carbon markets increasingly prioritize durability, verification, and delivery certainty, Terradot’s acquisition of Eion underscores a broader shift toward consolidation and platform-building in the carbon removal sector.
