About
Mast Reforestation is a Seattle-based post-wildfire reforestation and CDR company that produces durable carbon removal credits via biomass burial of fire-killed trees. Its MT1 project in Montana delivered 4,277 Puro.earth-certified credits in January 2026 — the largest issuance to date under Puro’s Terrestrial Storage of Biomass methodology — and sold out within six weeks to buyers including RBC, Bain, BMO, and CNaught. The company also operates Silvaseed and Cal Forest nurseries and plans to scale to 150,000 tonnes/year by 2030.
