§ Private Profile · Princeton, NJ, USA
Carbon removal technology company applying enhanced rock weathering on farmland to permanently capture CO2, offering verified carbon credits.
Based in Princeton, New Jersey, Eion develops enhanced rock weathering technology that applies pulverized olivine to agricultural lands to permanently capture atmospheric carbon dioxide through natural mineralization. The enterprise provides farmers with a nature-based solution that improves soil pH while utilizing patented measurement methods to quantify the exact volume of sequestered carbon. Eion monetizes this process by selling permanent carbon removal credits to corporate buyers, securing early purchases from technology companies like Stripe. The firm raised over $12 million in Series A funding in 2022 from venture capital investors including AgFunder, Ridgeline, and Mercator Partners. After removing 500 tonnes of carbon dioxide in 2022, the organization targeted 8,500 tonnes for 2023 and aims to reach an annual removal capacity of 500,000 tons by 2026. The company was founded in 2020 by Adam Wolf and Elliot Chang.

Eion is a technology company specializing in carbon removal solutions through a nature-based approach called enhanced rock weathering (ERW). It partners closely with farmers and ranchers to apply pulverized minerals to agricultural fields, accelerating the natural process of carbon dioxide absorption and permanent sequestration in soil. Eion serves entities aiming to meet climate goals by providing scientifically verified, scalable, and cost-effective carbon removal services, selling carbon removal credits to corporate buyers. Their approach integrates seamlessly with existing agricultural systems, emphasizing practical scalability and economic viability for landowners[2][3].
Eion was founded by Adam Wolf and others with a background in climate technology and agriculture. The idea emerged from leveraging the Earth’s natural carbon cycle—specifically, ERW—to create a scalable carbon removal solution. Early traction came from developing a patented direct measurement method called soil fingerprinting, which rigorously verifies carbon removal by comparing before-and-after soil samples. This innovation helped Eion become the first enhanced weathering company to deliver carbon removal credits to major buyers like Stripe. The company closed a $12 million Series A funding round in December 2022, led by AgFunder and Ridgeline, signaling strong investor confidence[2][3].
Eion operates at the intersection of climate tech, agriculture, and carbon markets, riding the growing global trend toward nature-based carbon removal solutions. The timing is critical as corporations and governments increasingly commit to net-zero targets, creating demand for verified, permanent carbon offsets. Market forces such as rising carbon credit prices, regulatory pressure, and advances in soil science favor Eion’s approach. By enabling farmers to participate economically in carbon removal, Eion also strengthens rural economies and accelerates adoption of sustainable agricultural practices, influencing both the climate and agtech ecosystems[2][3].
Looking ahead, Eion is poised to expand its footprint across more agricultural regions, scaling its carbon removal impact and refining its measurement technology. Trends such as increasing corporate climate commitments, evolving carbon markets, and advances in soil analytics will shape its growth trajectory. Eion’s influence may grow beyond carbon removal to broader soil health and regenerative agriculture initiatives, positioning it as a key player in sustainable agriculture and climate solutions. Its practical, science-backed model offers a promising path to scalable, permanent carbon removal integrated with existing land use[2][3].
