Integrity

The verification report confirms additionality through an investment test and shows the VVB closed out multiple corrective actions before issuance, which supports some integrity. However, leakage is a major weakness because the verification report says it was not addressed while the monitoring report says it was deemed negligible, and reversal risk is also not clearly handled because no buffer pool is stated and reversal events are not properly addressed. The baseline is project-based and last reassessed in 2022, which is acceptable but not especially strong.

Transparency

Transparency is limited by missing core MRV values: verified and claimed emission totals are not found in the extracted record, and the usage monitoring method is not stated. The project does have a named verifier, Re Carbon Ltd., and multiple source documents are available, but the absence of key quantified monitoring inputs reduces auditability. The extraction confidence is medium, so the documentation is usable but not fully robust.

Claim Safety

Claim safety is weakened by the project-specific baseline and the unresolved leakage narrative. The project is explicitly marked as not CORSIA-eligible, which lowers dual-claim risk, but there is no CCP status and no clear evidence of a conservative, standardized baseline or quantified usage monitoring. The contradiction on leakage means the over-crediting risk cannot be treated as low.

Documentation

The documentation set is reasonably broad, with 18 documents used and both verification and monitoring materials present. Still, the verification report records many corrective actions and clarifications, and the crediting period conflicts between the verification report and the later PDD, which reduces confidence in document consistency. The medium extraction confidence also suggests at least one key source was not perfectly readable.

Overall

I privileged the later PDD for the more recent crediting-period and safeguard statements, but I did not fully override the verification report where it is more specific about audit findings and additionality. The contradictions on leakage, FPIC, CORSIA eligibility, reversal events, and crediting period materially reduce reliability, so the score is kept conservative. Because integrity remains above the gate threshold, the overall score is not capped, but the project still sits in a weak-to-moderate quality range.
