Audit Analysis

BioLesna Carrot River is a Canadian biochar project verified by 350Solutions under Puro.earth's 2022 methodology. Additionality is confirmed via an investment test and no reversal events have occurred, but the verification report flagged three material findings (unclear dry-mass protocol, spreadsheet discrepancies, inconsistent moisture values) with corrective actions still required. Leakage is neither quantified nor justified, and the project-specific baseline lacks a documented reassessment date, leaving moderate residual risk on the integrity and claim-safety dimensions.

Red Flags

  • Three material findings in the verification report (2025-02-27) require corrective action: unclear dry-mass calculation protocol, discrepancies between biochar production/sales spreadsheets, and inconsistent moisture content values for Euse.
  • Leakage deduction and justification are both absent from the extracted record; no quantified treatment is documented for a project type where displaced soil carbon or feedstock sourcing could generate leakage.
  • No buffer pool percentage is stated in any available document, leaving permanence risk unmitigated by a standardised safety margin.
  • Permanence claim not stated in available documents
