Clean Maine Carbon

Audit Analysis

Clean Maine Carbon is a biochar project with strong inherent permanence (carbon locked in soil) and VVB-confirmed additionality, but it carries notable gaps in leakage treatment, buffer pool allocation, and measurement calibration. The verification report identified three material findings requiring corrective action, and several key monitoring parameters (fnrb, usage rates, CORSIA status) are absent from the extracted record. The exact match between claimed and verified ERR is reassuring for claim safety, but the overall evidence base is incomplete.

Project Description

Red Flags

• ⚠Three material findings in the verification report: biochar weigh scale and moisture analyzer lack traceable calibration, and electricity consumption is estimated rather than directly measured — all with required corrective actions
• ⚠No leakage deduction or justification stated in any available document, despite biochar production involving energy inputs and potential displacement effects
• ⚠No buffer pool percentage stated, leaving permanence risk unquantified despite the project's reliance on customer attestations for non-combustion
• ⚠Monitoring period spans only 5 days (14–18 August 2024), raising questions about representativeness of the verified ERR
