Audit Analysis

A Puro.earth biochar removal project with VVB-confirmed additionality and a verified ERR that exactly matches the claimed figure (207 tCO₂e). The project demonstrates conservative operational adjustments (carbon content revised downward, LCA updated) but leaves notable gaps in permanence mechanisms (no buffer pool stated), leakage treatment, and baseline reassessment timing. Overall a moderately well-documented removal credit with some structural transparency gaps.

Red Flags

  • Leakage deduction and justification are entirely absent from the extracted record, leaving no documented treatment of displaced emissions
  • Project-specific baseline with no stated reassessment date, limiting confidence in long-term baseline validity
