Integrity

Additionality is supported and was confirmed by an independent verifier in the verification report, which is a strong positive. However, permanence is weakened: reversal events are reported and no buffer pool percentage is disclosed in the extracted record, and the baseline has not been shown to be recently reassessed (baseline_last_reassessed not found). Leakage is recorded as a quantified justification with a 0% deduction in the verification report (positive), but the absence of disclosed buffer and the reported reversals reduce overall robustness.

Transparency

The verification report and monitoring report name the VVB (IBOPE) and provide a monitoring period, and many documents were used (n=23). Nevertheless, essential inputs are missing from the extracted record (grid emission factor, buffer pool percentage, FNRB method) and extraction confidence is only medium. Multiple contradictions across the PDD, monitoring, and verification documents further weaken transparency and traceability.

Claim Safety

There is a material over‑crediting risk: verification and monitoring reports disagree markedly on total emissions reductions (verification reported 82,711 in 2013 versus monitoring-reported values 50,265 and 40,169 in later monitoring documents). Leakage is documented as quantified with a 0% deduction in the verification report, which reduces leakage concern if accurate, but the ERR contradictions and unknown CORSIA/CCP status raise double‑claim and greenwashing risks.

Documentation

Documentation quantity is reasonable (23 documents) and the verification report is present (2013). However, extraction confidence is medium and several important fields are null or not stated in the extracted record. There are multiple contradictions between documents (see contradictions list), and some key documents are dated (most verification material from 2013; PDD records from 2011 and 2020), reducing clarity and recency.

Overall

I privileged verification and monitoring reports for operational and measured values (ERR figures, leakage justification, reversal reporting) because these are verification-level documents that directly assess performance. For governance items like the existence of a grievance mechanism, I gave weight to the later PDD entry claiming a grievance mechanism exists. Contradictions addressed: (1) Grievance mechanism — newer PDD (2020) indicates a grievance mechanism exists and I accept that as current for stakeholder processes. (2) Additionality test type — monitoring/verification documents state a barrier test while an earlier PDD listed combined; I privileged the verification/monitoring statement as it reflects the VVB assessment. (3) Leakage justification — verification report documents a quantified justification and I privileged that over an earlier PDD claim of not addressed. (4) Safeguards — verification report mentions safeguards while an older PDD did not; I privileged the verification report. (5–6) ERR contradictions — large discrepancies between verification (82,711) and monitoring reports (50,265 / 40,169); I privileged verified monitoring/verification documents for numbers but treat the inconsistency as a reliability issue that lowers scores. (7) Crediting period — monitoring indicates 2010–2020, the PDD lists a much later period; I treated the verification/monitoring dates as authoritative for historical crediting but flagged the PDD discrepancy as an unresolved governance issue. These contradictions and missing permanence/buffer details drive downward adjustments to integrity, claim safety, and documentation, yielding the overall score above.
