Score Breakdown

Integrity

verified Additionality was confirmed by the VVB using an investment test, which supports the project case.

missing Leakage treatment is only described as deemed negligible, while one earlier document reportedly said it was not addressed; the crediting period also conflicts across documents.

Transparency

verified The issuance record reports 62,780 verified reductions, matching the amount claimed, which supports registry consistency.

missing Key monitoring details such as the usage monitoring method and verification of usage rates are not stated in the extracted record.

Claim Safety

verified The verified and claimed emission reductions are identical, which reduces immediate over-issuance concern in the issuance record.

missing The project is not CORSIA-eligible, but CCP status is not stated and the baseline is project-specific rather than a more conservative standardized approach.

Documentation

verified Nine documents were used and no material findings or corrective actions were reported in the issuance record.

missing Extraction confidence is only medium, and several important items are not found in the available documents, including buffer pool coverage and safeguard documentation.

Detailed Analysis

Integrity

The issuance report shows additionality was confirmed by the VVB through an investment test, and no material findings or corrective actions were reported. The project is an avoidance project, so reversal risk is lower than for removals, but buffer pool coverage is not stated and there are no reversal details in the extracted record. Leakage is described as deemed negligible, yet the contradiction log says an earlier document treated leakage as not addressed, which weakens confidence in the integrity case.

Transparency

The registry record shows 62,780 verified reductions and the same amount claimed, which is a positive sign for issuance consistency. However, the usage monitoring method is not found, usage rates are not verified, and the extracted record does not provide a public-facing level of MRV detail beyond the issuance summary. The medium extraction confidence also limits transparency confidence somewhat.

Claim Safety

Claim safety is helped by the exact match between claimed and verified reductions in the issuance record. Still, the baseline is project-specific, the leakage justification is contested across documents, and CCP status is not stated, so the risk of over-crediting cannot be dismissed. The project is explicitly not CORSIA-eligible, which reduces one channel of claim risk but does not resolve the broader quality concerns.

Documentation

The record draws on nine documents, and the issuance report is dated 2013-06-17, which is reasonably close to the monitoring period. Even so, extraction confidence is only medium, one evidence document is listed as unknown, and several core items are missing or not stated, including buffer pool coverage, safeguard documentation, and monitoring method details. The contradictions on safeguards, leakage, and crediting period further reduce documentation quality.

Overall

Overall, this is a middling-quality VCS hydropower issuance record with a solid additionality signal and clean claimed-versus-verified issuance numbers, but meaningful documentation and reliability gaps. I privileged the later issuance record dated 2013-06-17 for the final values on safeguards, leakage, and crediting period because it is the more recent and likely authoritative issuance document, while noting the earlier conflicting documents in the assessment. The contradictions materially reduce confidence, especially because they touch safeguards, leakage treatment, and the project term.

Audit Analysis

The project has some strengths: additionality was confirmed by the VVB, no material findings were reported, and the issuance record shows claimed and verified emissions reductions match exactly. However, reliability is weakened by document contradictions on safeguards, leakage treatment, and the crediting period, and several key MRV details are not stated in the extracted record.

Project Description

This carbon project is based in Ziqiang town, Zhijin County, Bijie City, Guizhou Province, P.R.China. The dam is located 74km from Zhijin County and 94km from Guiyang city, with geographical coordinates of east longitude +106.0839° and north Latitude +26.6778°.

Red Flags

The extracted record contains contradictions on safeguards, leakage justification, and the crediting period, which reduces confidence in the documentation trail.
Safeguards, grievance mechanism, FPIC, and usage monitoring details are not found in the available documents.

Cosa migliorerebbe questo punteggio

Provide the full monitoring and verification package showing leakage treatment, safeguard implementation, and the rationale for the final crediting period.
Disclose buffer pool treatment, any reversal monitoring provisions, and a clear registry statement on CCP status and other claim restrictions.
