Audit Analysis
The Lurin biochar project in Peru demonstrates solid additionality (combined test confirmed by SGS India) and strong chemical permanence (H/Corg ratio of 0.414 well below the 0.7 threshold), with 100% of claimed credits verified. However, the project-specific baseline, unquantified leakage treatment, limited LCA boundary (cradle-to-gate), and several operational material findings (uncalibrated instruments, incomplete historical records) temper confidence in the overall claim.
Red Flags
- LCA boundary limited to cradle-to-gate, excluding downstream use and end-of-life impacts, as noted in the verification report material findings
- Leakage deemed negligible without a quantified deduction or detailed justification in the extracted record
- Incomplete historical production records prior to January 2024, only partially remediated by a new registry
- Buffer pool percentage not stated in any available document, leaving permanence risk unmitigated by a standard mechanism
