Terradot Acquires Eion in Strategic Carbon Removal Market Consolidation

06.02.2026

Carbon removal technology company Terradot has announced the acquisition of competitor Eion, marking a significant consolidation in the enhanced rock weathering sector. The transaction was primarily driven by institutional investors, including sovereign wealth funds, seeking to partner with organizations capable of executing large-scale carbon removal contracts.

According to Eion CEO Anastasia Pavlovic Hans, the company's limited scale made it challenging to meet the requirements of major institutional buyers, ultimately leading to the acquisition decision.

Technology Overview

Both organizations specialize in enhanced rock weathering (EWR), a carbon dioxide removal methodology that involves distributing pulverized mineral rocks across agricultural land. This process accelerates natural weathering reactions that sequester atmospheric CO2, offering a potentially cost-effective carbon removal solution. However, successful implementation requires extensive geographical distribution and significant operational scale.

Operational Differences

The two companies have pursued distinct geographical and mineralogical strategies:

• Terradot: California-based with primary operations in Brazil, utilizing basalt as the core mineral substrate
• Eion: U.S.-focused operations employing olivine-based rock amendments

Market Dynamics

Industry data from CDR.fyi indicates a persistent pricing gap between EWR providers' target pricing and buyers' willingness to pay, highlighting ongoing market maturation challenges in the carbon removal sector.

Investment Backing

Terradot's investor portfolio includes Gigascale Capital, Google, Kleiner Perkins, and Microsoft, while Eion has received backing from AgFunder, Mercator Partners, and Overture.
