Frontier buyers commit $33 million for Eion's carbon removal credits

Frontier buyers, including Stripe, Google, and Shopify, signed $33 million in offtake agreements with Eion for the removal of 78,707 tonnes of CO₂ between 2027 and 2030. Eion deploys enhanced rock weathering using olivine on agricultural fields in the Southern and Midwestern United States. The olivine serves as a cheaper alternative to agricultural lime for farmers, converting atmospheric CO₂ into bicarbonate stored in the ocean. This deal facilitates the scaling of enhanced weathering and provides crucial data for the scientific validation of the method.
