Score Breakdown

Integrity

verified Additionality was confirmed by the VVB, and the project uses the ACM0002 methodology under Gold Standard.

missing Leakage is marked as not addressed in the monitoring report, and the record shows no buffer pool or reversal detail.

Transparency

verified The verification report is identified, with a defined monitoring period and a named VVB, which supports basic traceability.

missing Total ERs claimed versus verified are not stated, and the extraction confidence is only medium, limiting documentation clarity.

Claim Safety

verified The project is a small hydro renewable-energy activity with VVB-confirmed additionality, which supports a moderate claim-safety profile.

missing The monitoring report leaves leakage unaddressed, and the project is listed as CORSIA-eligible while CCP status is not mentioned, leaving dual-claim risk unresolved.

Documentation

verified Multiple official documents were used, including the PDD, validation report, verification report, and monitoring report.

missing Several key fields are not stated in the extracted record, and the monitoring period ends in 2013 while the verification report is dated 2014, indicating only moderate recency.

Detailed Analysis

Integrity

The verification report states that the project meets Gold Standard requirements and that additionality was confirmed by the VVB, which is a meaningful positive. However, the monitoring report says leakage is not addressed, and there is no buffer pool or reversal detail in the extracted record, so permanence and leakage controls are only partially supported. The project uses ACM0002, but the baseline and leakage treatment are not consistently documented across the available files.

Transparency

The record includes a named verifier, a monitoring period, and a verification report date, which helps traceability. Still, total emissions reductions claimed versus verified are not stated, usage monitoring is not described, and the extraction confidence is only medium, so the public MRV picture is incomplete. The absence of several quantified fields limits transparency.

Claim Safety

Claim safety is moderate because the project is a small hydro renewable-energy activity and additionality was confirmed by the VVB. That said, the monitoring report does not address leakage, while the PDD reportedly considered it negligible, so the over-crediting risk is not fully resolved. The project is marked as CORSIA-eligible, but CCP status is not mentioned, leaving some dual-claim uncertainty.

Documentation

Documentation quality is fair because multiple official documents were available and 15 extracted facts were used. The verification report is reasonably detailed, but several important fields are missing or not stated, including verified ER totals, leakage quantification, and usage monitoring. The monitoring period is older than the verification date, and the medium extraction confidence suggests at least one source was not perfectly readable.

Overall

I privileged the more recent monitoring report over the older PDD and validation report where they conflicted, because it is the latest project-specific evidence; that means I treated leakage as not addressed and the baseline/additionality wording as less reliable than the earlier documents. I also privileged the verification report for the crediting-period statement because it is the formal assurance document, but the contradiction with the validation report still lowers confidence. Overall, the project looks viable but not high-confidence due to multiple document inconsistencies and incomplete leakage and claims documentation.

Audit Analysis

This is a small hydro project with VVB-confirmed additionality and no reversal events reported, but the evidence base has several reliability issues. The main concerns are contradictory statements across documents on the additionality test, baseline method, leakage treatment, and crediting period, plus leakage is not addressed in the monitoring report.

Project Description

Developer: Climate Bridge (Shanghai) Ltd. Type: Small, Low - Impact Hydro Size: Microscale Methodology: ACM0002 Grid-connected electricity generation from renewable sources Crediting period: 2010-04-05 → 2017-04-04 Estimated annual credits: 4843 tCO2e SDGs: Goal 7: Affordable and Clean Energy, Goal 9: Industry, Innovation and Infrastructure, Goal 13: Climate Action

Red Flags

  • The monitoring report and validation report disagree on additionality, baseline approach, leakage treatment, and crediting period, which weakens confidence in the record.
  • Leakage is not addressed in the monitoring report even though the PDD reportedly treated it as negligible, creating uncertainty about over-crediting risk.

Cosa migliorerebbe questo punteggio

  • Provide a reconciled document trail explaining the differences between the validation report, monitoring report, and verification report on additionality, baseline, leakage, and crediting period.
  • Publish quantified leakage treatment, verified emissions reduction totals, and clearer registry/claim status information, including whether CCP approval exists.

Questi suggerimenti indicano quali prove pubbliche aggiuntive potrebbero migliorare il livello di confidenza di questa valutazione. Non garantiscono un punteggio futuro più alto.
