Eion leads cutting-edge geoscience and agronomic research to put enhanced weathering science and measurement into practice and lay the groundwork for gigaton-scale carbon removal.
At Eion, we believe that transparency and collaboration are crucial for making enhanced weathering a reliable and scalable solution for carbon removal.
We openly share our methods and results to foster accountability and ensure stakeholders can rely on our processes and outcomes.
We partner with farmers, researchers, and other innovators to drive progress, combining knowledge and resources to accelerate advancements in the field.
Measuring carbon removal has long been the difficult part of enhanced weathering—how do you measure something that’s no longer there? Eion has pioneered the use of soil itself as a natural gauge. By identifying specific markers or “tracers” left behind after rock weathers, we directly observe the carbon removal process. Our patented approach to measurement, reporting, and verification (MRV) can be adapted across minerals.
Eion is committed to environmental integrity at all steps in our enhanced weathering process. We implement rigorous protocols to screen for environmental health and safety concerns before and after application, ensuring safe and responsible deployment of olivine at scale. Our R&D field trials assess olivine’s effects on soil pH and nutrients, plant uptake, and downstream air and water quality.
Eion cofounded the first industry coalition, the Enhanced Weathering Alliance (EWA), and we’re key scientific collaborators on industry-first methodologies like Isometric and Puro. We’re also a close partner of critical industry bodies working to advance carbon dioxide removal and enhanced weathering technologies, including Cascade, the Carbon Removal Alliance (CRA), and the Carbon Business Council (CBC).
