CATANDUVA LANDFILL GAS PROJECT

Integrity

The validation report confirms additionality through VVB review, and the project uses a project baseline under ACM0001, which supports the core crediting logic. That said, leakage is recorded as 0% while the same report says leakage justification is not addressed, and reversal events are also not addressed, so permanence and leakage robustness are only moderate. The presence of four corrective actions further reduces confidence in the robustness of the underlying accounting.

Transparency

Transparency is mixed because the project is on the VCS registry and the verifier is named, but key MRV outputs are missing from the extracted record. Total ERs claimed and verified are not stated, the monitoring period is not found, and the usage monitoring method is also absent. This limits the ability to independently check issuance and performance claims.

Claim Safety

Claim safety is weakened by the combination of CORSIA eligibility and incomplete leakage treatment. The project is not shown to be CCP-approved, which avoids one specific overlap risk, but CORSIA eligibility means the credit may still be used in a higher-scrutiny claims context. Because the validation report says leakage is not addressed, over-crediting risk is not fully controlled.

Documentation

The documentation set appears reasonably broad, with a PDD and validation report among the evidence documents and medium extraction confidence. Even so, four corrective actions remain open, and several important fields are missing from the extracted record, including the monitoring period and usage monitoring method. The recency of the crediting period is clear, but the documentation still looks incomplete for a high-confidence assessment.

Overall

The project scores in the middle range because it has some core strengths, but the evidence package is not fully tight. I privileged the validation report dated 2025-10-24 over the earlier unknown-source note on leakage because it is the higher-priority and more recent document; that means I treated leakage as not addressed rather than quantified. The contradiction itself lowers reliability, and the unresolved corrective actions reinforce that downward adjustment.
