Mast Reforestation Sells Out MT1 Credits, Accelerates Biomass Burial Expansion Plan

New updates have been reported about Mast Reforestation.

Mast Reforestation has fully sold the 4,277 biomass burial carbon removal credits from its MT1 project in southern Montana in under six weeks, underscoring strong market demand for high-integrity removals and validating its business model. The credits, issued in January 2026 under Puro.earth’s Terrestrial Storage of Biomass methodology, were purchased by buyers including Bain & Company and BMO, and represent the registry’s largest issuance to date as well as one of the world’s fastest carbon removal project timelines at roughly nine months from excavation to issuance.

MT1 monetizes more than 10 million pounds of wildfire-killed trees buried in a purpose-built underground chamber instead of being pile-burned, creating 100-year certified storage with monitoring, reporting, and verification commitments and contributing to broader scientific research on biomass burial durability. The project, rated A by BeZero Carbon—an achievement held by fewer than 8% of non-nature-based carbon removal projects—uses carbon credit revenue to directly finance post-wildfire restoration, with Mast now planting over 6,000 native conifer seedlings at the severely burned 2021 Poverty Flats Fire site using stock from its Silvaseed nursery.

For Mast, the rapid credit sell-out supports CEO Grant Canary’s positioning of biomass burial and reforestation as “investable infrastructure,” built on predictable project delivery, third-party verification, and clear linkage between credit revenue and ecosystem recovery. The company, recently named one of Fast Company’s Most Innovative Companies of 2026, is scaling this model across western North America, identifying more than 6.5 million tonnes of eligible burned biomass in Montana alone and targeting a second biomass burial project to complete construction in 2026 with credits expected in 2027.

Strategically, Mast aims to deploy 150,000 tonnes of biomass burial annually by 2030 while leveraging its seed and seedling nurseries, Silvaseed and Cal Forest, which are critical to the western U.S. forestry supply chain and enable vertically integrated wildfire recovery operations. The company has also joined the Direct Storage of Biomass Coalition to help shape standards, policy, and market understanding for this carbon removal pathway, and is now engaging prospective offtakers for future projects following the MT1 sell-out, signaling a potential pipeline of repeat corporate buyers and longer-term offtake agreements.
