Integrity

The verification report confirms additionality through an investment test and says the VVB, TÜV NORD CERT GmbH, validated the project. However, leakage is not addressed, reversal events are not addressed, and there is no buffer pool information, so permanence and leakage robustness remain weak. The large number of findings in the verification report also weighs on integrity.

Transparency

Transparency is only moderate because the project has a named verifier and a clear monitoring period, but key MRV outputs are missing from the extracted record. Total claimed and verified emission reductions are not stated, and the usage monitoring method is not found. The absence of these core figures limits public traceability of the claim.

Claim Safety

Claim safety is constrained by missing evidence on leakage, permanence, and dual-claim status. The project uses a project-specific baseline under AM0013, but there is no stated leakage deduction and no information on CORSIA eligibility or CCP status. The verified usage rate of 74% is helpful, but without the assumed rate or monitoring method it is hard to judge over-crediting risk.

Documentation

Documentation quality is mixed: the record draws on a PDD, monitoring report, and verification report, and the extraction confidence is medium rather than low. Still, the verification report lists seven corrective action requests and three clarifications, which suggests substantial issues during verification. The crediting period in the verification report differs from the PDD, and I privileged the later verification report because it is more recent and reflects the verified status.

Overall

Overall, this is a mid-quality project with some real strengths but notable evidence gaps. I privileged the verification report over the older PDD for the crediting-period discrepancy because it is later and more authoritative for verified status, but the contradiction still lowers reliability. The many findings, missing leakage and permanence information, and incomplete MRV disclosure keep the score below a strong level.
