Frontier facilitates $4.5M carbon removal prepurchases from nine companies

Frontier has facilitated $4.5 million in carbon removal prepurchases from nine companies, including Alithic, Alt Carbon, and Capture6, on behalf of buyers Stripe, Shopify, Alphabet, H&M Group, and Match (via Watershed). This fourth round of prepurchases supports projects integrating carbon removal into existing large-scale industries to reduce costs and accelerate scale. Examples include Planeteers, an ocean alkalinity enhancement company working with water treatment plants, and Exterra, which embeds its approach into mining processes. The prepurchases cover diverse methodologies such as direct air capture, field weathering, and mineralization, with volumes ranging from 285 to 1,851 tonnes per project.
