Step 1: Carbon Removal Quantification
Carbon storage is calculated from biochar output, its fixed carbon content, and how stable the final use is. Standard methods allow each ton of biochar to be converted into measurable carbon removal, giving buyers clear and trusted data.
Step 2: Technology Check & Method Alignment
Projects must follow global rules. The BST-50S biochar machine passed Puro.earth’s review, proving that its production and tracking process meets international standards. This ensures credit quality and long-term storage, which is key for ESG and net-zero buyers.
Step 3: Certification & Credit Issuance
Independent auditors check projects before credits are issued. One Biochar Carbon Removal (BCR) credit equals one ton of CO₂ locked away. At USD 150–250 per ton, certification turns carbon removal into a strong income stream.
Step 4: Trading & Revenue Generation
BCR credits are sold to global companies, banks, and governments to offset emissions. Demand is high from firms with science-based targets, making BCRs a leading carbon removal option. Together with biochar product sales, credit trading boosts both project income and stability.
