Score Breakdown

Integrity

verified The validation documentation indicates additionality was confirmed by the VVB.

missing Baseline approach and leakage treatment are not evidenced in the extracted record (baseline method not stated; leakage not addressed).

Transparency

verified The monitoring report provides a clear monitoring period (2012-05-01 to 2016-08-24) and a verified ER figure of 224,957 tCO2e.

missing Claimed ERs are not found in the extracted record, limiting the ability to reconcile claimed vs verified outcomes.

Claim Safety

verified A specific grid emission factor is reported (0.7737), supporting replicability if underlying calculations are available.

missing CORSIA eligibility and CCP status are not stated in available documents, and leakage/baseline evidence gaps elevate over-crediting and claims risk.

Documentation

verified Multiple document types are present (monitoring report and validation report) with high extraction confidence.

missing Several key fields are missing from the extracted record (e.g., baseline method, additionality test type, grievance mechanism, FPIC).

Detailed Analysis

Integrity

The validation documentation indicates additionality was confirmed by the VVB (validation report). However, the extracted record does not state the additionality test type, the baseline method, or when the baseline was last reassessed, which are central to assessing ACM0002 baseline robustness. Leakage is flagged as not addressed and no leakage deduction is provided (monitoring report), creating a material integrity evidence gap even though no material findings or corrective actions are reported.

Transparency

The monitoring report clearly specifies the monitoring period (2012-05-01 to 2016-08-24) and reports verified emission reductions of 224,957 tCO2e (monitoring report dated 2022-09-09). The VVB is identified as Shenzhen CTI International Certification Co., Ltd (project documentation). However, the claimed ER total is not found in the extracted record, limiting reconciliation between what was claimed and what was verified.

Claim Safety

Over-crediting risk cannot be fully screened because the baseline method is not stated in the extracted record, even though the project uses ACM0002 version 06 (project documentation). Leakage is not addressed and no deduction is reported (monitoring report), which weakens confidence in conservative accounting. CORSIA eligibility and CCP status are not stated in available documents, increasing the risk of ambiguous downstream claims and buyer misrepresentation.

Documentation

The extracted record includes at least a monitoring report and a validation report, and the minimum extraction confidence is high, supporting basic document reliability. The monitoring report is relatively recent (2022-09-09) and includes a defined monitoring period and verified ERs. Nonetheless, several important social and accounting elements are not evidenced in the extracted record (e.g., grievance mechanism, FPIC, baseline method), reducing completeness.

Overall

No contradictions were identified in the extracted record, so no score adjustments were needed for internal inconsistencies. The overall score is driven by moderate documentation strength (multiple documents, high readability) and VVB-confirmed additionality, balanced against major evidence gaps on baseline specification and leakage treatment. These gaps increase integrity and claims risk for an avoidance project under ACM0002, even with no reported material findings or corrective actions.

Audit Analysis

This VCS hydropower project is supported by a monitoring report and validation documentation, with VVB-confirmed additionality and no reported material findings. However, key integrity elements are not evidenced in the extracted record, including the baseline approach and any leakage treatment, which increases over-crediting risk for an ACM0002 grid-connected renewable project.

Project Description

The Zhoubai Hydroelectric Project is a new, 22 MW reservoir hydropower plant that generates electricity by utilizing existing hydrological resources. The Project's purpose is to displace electricity generation from grid-connected fossil fuel-fired power plants, reducing carbon emissions and generating certified emission reductions (CERs). With a flooded area of 1.91km2 and a power density of 11.52 W/m2, it has the potential to make a significant impact in the fight against climate change.

Red Flags

Baseline approach and timing of any baseline reassessment are not stated in the extracted record, despite being central to ACM0002 crediting integrity.
Leakage is marked as not addressed and no leakage deduction is provided, creating an evidence gap on a core accounting element.

Cosa migliorerebbe questo punteggio

Disclose the baseline approach used under ACM0002 (including data sources, grid EF derivation year(s), and when the baseline was last reassessed) in the public documentation set.
Provide explicit leakage assessment and, if applicable, a quantified leakage deduction (or a justified negligible-leakage conclusion) consistent with the methodology and monitoring report.

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