Buried Treasure

Integrity

The verification report confirms additionality through a combined test and says there were no material findings, which supports the project’s core integrity case. At the same time, leakage is not addressed, reversal events are not discussed, and buffer pool coverage is not stated, so permanence and leakage controls remain weakly evidenced. The project therefore scores in the middle rather than high on integrity.

Transparency

The monitoring and crediting periods are clearly identified, and the VVB is named as SCS Global Services in the verification report. But the record does not state total claimed versus verified reductions, usage monitoring method, or other registry completeness details, leaving important transparency gaps. With several core MRV fields missing, the documentation is only partially auditable from the extracted record.

Claim Safety

The use of a project baseline under the CAR Mexico Landfill Project Reporting Protocol Version 2.0 gives some methodological grounding. However, leakage justification is explicitly not addressed, and the record does not state CORSIA eligibility or CCP status, so over-crediting and dual-claim risk cannot be ruled out from the available documents. The absence of quantified leakage treatment keeps claim safety below average.

Documentation

The file includes a recent verification report dated 2023-12-16 and identifies the monitoring period, which helps document recency. Still, the extracted record shows multiple null or not-stated fields, the evidence document list includes an unknown item, and extraction confidence is only medium. No corrective actions were required, but the overall documentation package is incomplete for a high-confidence assessment.

Overall

There are no contradictions listed in the extracted record, so no document hierarchy decision was needed. The main limitation is not inconsistency but missing evidence: leakage, reversal risk, safeguards, and several MRV outputs are not stated in the available documents. Given the medium extraction confidence and incomplete disclosure, the project should be treated as moderately risky rather than robust.
