Audit Analysis
The Catanduva Landfill Gas Project is a well-understood VCS methane-avoidance project under the established ACM0001 methodology, with VVB-confirmed additionality and inherent permanence from methane destruction. However, significant documentation contradictions (grid emission factor, FPIC status, benefit-sharing) and the absence of any monitoring data or buffer-pool specification limit confidence in the current evidence base. CORSIA eligibility introduces a dual-channel risk that is not offset by a stated CCP position.
Red Flags
- Grid emission factor discrepancy: the validation report states 0.25 while an appendix states 1.3 — a 5× difference that is unresolved and could materially affect the baseline calculation.
- FPIC contradiction: the PDD (Jan 2025) states FPIC was conducted, but the validation report (Oct 2025) records it as not conducted; the VVB's assessment is privileged but the inconsistency undermines safeguards confidence.
- CORSIA-eligible with no stated CCP status, creating a dual-channel crediting risk that is not explicitly managed in the available documents.
Credit Vintages
