Turning wood residues into biochar takes equipment, energy and a way to get the material into use. Carbon credits help fund that work by giving durable carbon removal a market value. Organizations pay for verified removal, and the revenue helps producers turn more biomass into useful, carbon-rich material.
For Wakefield, that connects two groups of customers: those who use biochar and those who fund carbon removal. Both help make a system possible in which wood residues become a resource for soil improvement and long-term carbon storage.1
What a biochar carbon credit represents
Plants absorb CO₂ as they grow. Making biochar stabilizes part of that captured carbon, and placing it into a durable use keeps it stored. Our article on biochar for soil carbon sequestration and removal follows that physical process in more detail.
A carbon-removal credit gives the measured climate benefit a standard unit. Puro.earth calls its credits CO₂ Removal Certificates, or CORCs. Each CORC represents one metric tonne of verified net CO₂ removal.2 This lets organizations support documented removal through a purchase with a traceable record.
From production records to verified removal
The calculation starts with the amount of carbon in the biochar and how much is expected to remain stored. It then accounts for emissions from sourcing biomass, production, transport and final use. The assessment also considers the project’s baseline—what would have happened without it—and indirect emissions caused by the project.3
A crediting methodology sets the rules for this work. Under the Puro framework, producers document the biomass source, measure the biochar’s properties and track where it goes. Records connect production with an eligible use that stores carbon. Independent auditors review the evidence and the net-removal calculation.3
Once verified results are accepted, credits are issued in a registry. A buyer can then retire credits, recording that they have been used for a climate claim and taking them out of circulation.2 Measurement, verification and retirement give the removal a record that follows it from the project to the buyer.
How carbon finance supports Wakefield’s biochar
Wakefield turns woody residues into biochar for farms and other lasting uses. Carbon revenue helps cover processing, hauling and application costs, supporting more affordable access to the material.1
In our usual supply model, we retain the carbon-removal credits and market them through Accend. Customers purchase biochar for its practical uses, while organizations purchasing credits help finance the verified removal behind it. This gives the stored carbon an economic role alongside the material’s value in soil.
Wakefield’s carbon-removal work is documented in public project records. For example, the Puro registry record for Wakefield Biochar Facility 2 includes credit issuance and audit documents.4 Accend’s Wakefield project profile describes the production projects and how carbon finance supports their operation.1
