Frontier, a group of companies that formed to accelerate the development of carbon removal technologies, facilitated offtakes to remove 78,707 tons of CO2 between 2027 and 2030.

The agreement was signed with Eion, a carbon removal company deploying enhanced weathering in the Southern and Midwestern regions.

Frontier buyers will pay $33 million to remove 78,707 tons of CO2 between 2027 and 2030. Frontier facilitated purchases on behalf of Frontier Founding Members Stripe, Google, and Shopify, as well as Autodesk, H&M Group, JPMorgan Chase, Workday, and Salesforce. Additionally, Aledade, Canva, Match Group, Samsara, SKIMS, Skyscanner, Wise, and Zendesk have purchased via Watershed’s partnership with Frontier.

Eion sources olivine — a rock type that reacts quickly with CO2 — spreads it on agricultural fields, and measures how much CO2 is removed. The olivine reacts with rainwater to convert atmospheric CO2 into bicarbonate, which is stored permanently in the ocean. 

Olivine weathers quickly enough to remove CO2 faster than other enhanced weathering methods and is also a substitute for ag lime, a commonly used product to manage soil acidity. Olivine can be applied using existing agricultural practices and ends up costing farmers less because Eion sells carbon removal credits that subsidize the price.

“Eion has two big advantages: olivine weathers fast and farmers can adopt it easily,” said Hannah Bebbington, Head of Deployment at Frontier, in a statement. “This means they’ll deliver more carbon removal and more weathering data that can move the entire enhanced weathering field forward.”
