Mast Reforestation has sold and delivered the first batch of credits generated through its biomass burial and post-fire restoration project known as Mast Wood Preserve MT1.
With this success, the company has hit more than one milestone, including marking the largest issuance to date under Puro.earth’s Terrestrial Storage of Biomass methodology and being the first one to also finance post-wildfire revitalization, as well as achieving one of the fastest excavation-to-issuance timelines globally.
The credits were generated from the burial of more than 10 million pounds of trees killed by wildfires, which were deposited into an underground chamber designed for long-term storage. This process prevents the open-air burning of the dead trees, helping store away their CO2 content instead of letting it be released into the atmosphere.
Mast Reforestation employs a rigorous monitoring, reporting, and verification (MRV) system to track the proper execution of these operations. The company began monitoring in and above the biomass storage chamber in August 2025 and will continue the monitoring throughout the project’s 100-year duration.
After a comprehensive third-party verification, Puro.earth certified 4,277 carbon removal credits from the MT1 project, more than 80% of which were already sold to buyers on the voluntary carbon market. Credit buyers include the Royal Bank of Canada, CNaught, Muir AI, and SE Advisory Services—the global consulting arm of Schneider Electric.
With the secured funds and additional direct support, Mast will work on the post-wildfire reforestation of the area surrounding the biomass burial site in Bighorn County, Montana.
In 2021, this area got severely damaged by the Poverty Flats Fire, and its ruined ecosystem was unlikely to recover naturally during the next century and even beyond that.
To address this issue, in spring 2026, Mast will begin reviving this land by planting native conifer seedlings grown from wild-collected and locally adapted seed that are currently being cultivated at its commercial nurseries.

With this side of operations, the MT1 project offers a blueprint for a financial pathway to fund the restoration of ecosystems and communities affected by severe wildfire.
This valuable foundation and experience have driven Mast to work on expanding its pipeline of biomass burial projects in 2026, targeting tens of thousands of tonnes of CO2 removal which would help generate forest restoration funds for thousands of acres of fire-impacted territory.
