Post-wildfire restoration company Mast Reforestation announced that it has sold 100% of the carbon removal credits from its new biomass burial project in Montana, with all 4,277 credits purchased less than six weeks after issuance.

New buyers for the carbon credits included global management consulting firm Bain & Company and Canadian bank BMO, joining earlier participants including Royal Bank of Canada (RBC), CNaught, a major corporate buyer advised by SE Advisory Services, Muir AI, and others.

Founded in 2016, Seattle-based Mast manages and finances reforestation projects after forests are destroyed by wildfires or other events, and has specialized in carbon-financed reforestation in the U.S. and Canada since 2020.

Biomass burial involves burying fire-destroyed trees instead of burning them, which is the typical post-wildfire practice and would release greenhouse gas emissions. The burial process enables reforestation of the area and generates carbon removal credits from buried trees that would otherwise release stored carbon if piled and burned.

Launched in 2025, the Montana project, Mast Wood Preserve MT1, was the company’s first restorative biomass burial project to remove fire-killed trees in southern Montana as part of efforts to restore 900 acres of forestland affected by a severe fire in 2021.

The sell-out follows MT1’s issuance in January 2026 under the Puro.earth registry, marking the largest issuance to date under Puro.earth’s Terrestrial Storage of Biomass (TSB) methodology, and was one of the fastest project development timelines globally for a carbon removal project in nine months, according to the company.

Grant Canary, CEO of Mast Reforestation said:

“The sell-out of MT1 carbon removal credits validates this new pathway for financing wildfire recovery. We delivered high-quality, third-party verified carbon removal on a rapid timeline—just nine months from start of construction to issuance. This delivery and sell-out timeline shows that durable carbon removal can be delivered in months, not years. The revenue from sales is now funding restoration on the ground.”

The company said that MT1 is the first Biomass Carbon Removal and Storage (BiCRS) project to use carbon credit revenues to directly finance post-wildfire reforestation and ecosystem recovery. Proceeds from credit sales are currently funding restoration at the site, where planting activities are already underway.

The company said it is advancing additional projects across western North America, targeting completion of a second project in 2026 with expected issuance in 2027, and aiming to scale deployment to 150,000 tons annually by 2030.

Sam Israelit, Partner and Chief Sustainability Officer at Bain & Company said:

“High-integrity carbon removal is an important part of Bain’s strategy to address residual emissions while helping scale the climate solutions the world needs. Mast’s MT1 project stood out for combining durable carbon removal with meaningful post-wildfire recovery, demonstrating how biomass burial can deliver both environmental integrity and benefits to communities and ecosystems.”
