Guohua Wulate Zhongqi Phase I 49.5 MW Wind Farm Project
Score Breakdown
Integrity
verified The validation/verification record indicates additionality was confirmed by the VVB using an investment test.
missing Baseline/MRV inputs show material inconsistencies across documents (notably grid emission factor and ER totals), increasing over-crediting risk.
Transparency
verified Key MRV elements are present in the extracted record (methodology ACM0002 v20.0, monitoring period 2019-08-01 to 2022-07-31, and matching claimed vs verified ERs in the latest monitoring record).
missing Multiple contradictions across monitoring/validation documents reduce transparency and make it hard to reconcile what was actually monitored and verified.
Claim Safety
verified The project is explicitly not CORSIA-eligible, reducing aviation-claim and double-claim channel risk.
missing Conflicting ER totals and grid emission factors across documents elevate greenwashing/over-crediting risk even if the latest figures reconcile internally.
Documentation
verified A relatively complete document set is indicated (PDD, monitoring report, validation report, issuance) with high extraction confidence and 28 documents used.
missing Corrective actions were required (date-period correction in the monitoring report), and repeated cross-document inconsistencies suggest document control issues.
Detailed Analysis
Integrity
The validation/verification record indicates additionality was confirmed by the VVB using an investment test (validation/verification documentation referenced in the extracted record). The project applies a project-specific baseline under ACM0002, but the baseline input (grid emission factor) is inconsistent between a 2019 monitoring report and a 2022 validation report (1.0755 vs 0.84045), which can materially change ERs. Leakage is reported as a 0% deduction with a quantified justification in the 2022 monitoring report, but an earlier monitoring report states leakage was not addressed, weakening confidence in consistent application. No reversal buffer is stated (not typically applicable for wind), and no reversal events are reported in the extracted record.
Transparency
The latest monitoring record provides a clear monitoring period (2019-08-01 to 2022-07-31) and shows claimed ERs equal verified ERs (both 349,762) in that record. The VVB is identified as China Classification Society Certification Co., Ltd., supporting traceability of assurance. However, transparency is undermined by multiple contradictions across monitoring/validation documents on core quantitative parameters (ER totals, grid emission factor) and even the crediting period dates, making reconciliation difficult for an external reviewer.
Claim Safety
The project is explicitly not CORSIA-eligible, which reduces the risk of aviation-related double claiming; CCP status is not stated in the extracted record, leaving some uncertainty for broader integrity labeling. Over-crediting risk is elevated because the grid emission factor differs substantially across documents (0.84045 vs 1.0755) and because verified ER totals conflict between validation reports (349,762 vs 811,737). While the latest monitoring report shows internal consistency (claimed equals verified), the cross-document inconsistencies increase greenwashing risk for public claims.
Documentation
The extracted record indicates a reasonably complete documentation package (PDD, monitoring report, validation report, issuance) and a high extraction confidence across 28 documents. Nonetheless, corrective actions were required to fix an incorrect reported period in the monitoring report, indicating quality-control issues. In addition, repeated contradictions across documents (including safeguards and key quantitative parameters) suggest document versioning or reporting inconsistencies that reduce documentary reliability.
Overall
I privilege the more recent documents where conflicts exist (e.g., the 2022-11-15 monitoring report and 2022-12-19 validation report) because they are later in time and more likely to reflect the current registered configuration and latest verification cycle. Specifically: I use 349,762 tCO2e as the operative ER figure because it is consistent between the latest monitoring record’s claimed and verified values, while older figures (78,402 and 811,737) likely relate to different periods or earlier document versions; however, the magnitude of the discrepancy still warrants a score penalty. I use the 0.84045 grid emission factor from the 2022 validation report over the 1.0755 value in the 2019 monitoring report due to recency and validation-level authority, but the inconsistency materially affects integrity/claim safety. I use the 2019-08-01 to 2029-07-31 crediting period from the 2022 monitoring report over the 2009-08-01 to 2031-02-28 dates in the 2019 monitoring report, again due to recency, but the conflict indicates eligibility-boundary risk. Finally, safeguards/FPIC/grievance/benefit-sharing are treated as only partially reliable because earlier monitoring documentation contradicts later claims, lowering confidence despite the 2022 monitoring report stating they are in place.
Audit Analysis
This is a VCS wind project using ACM0002 with VVB-confirmed additionality and a clear monitoring period, and the claimed and verified ERs match in the latest monitoring record. However, multiple cross-document inconsistencies (ER totals, grid emission factor, crediting period, and safeguards/leakage statements) reduce confidence in baseline/MRV reliability and increase over-crediting and reputational risk.
Project Description
Guohua Wulate Zhongqi Phase I 49.5 MW Wind farm Project was registered in Unfccc.int by CDM number of 2597 which is located in Urad Zhongqi, Bayan Nur League, Inner Mongolia Autonomous Region, P. R. China. The project was constructed and operated by Guohua CWP Bayannaoer Wind Power Co., Ltd. The total installed capacity of the proposed project is 49.5MW with 33 sets of turbines and a unit capacity of 1500kW. The estimated electricity output to NCPG is 124,300MWh per year.
Red Flags
- Large inconsistencies across documents for verified ERs (349,762 vs 811,737) and claimed ERs (349,762 vs 78,402), indicating data reliability issues.
- Grid emission factor differs materially between documents (0.84045 vs 1.0755), which can significantly affect credited reductions.
- Crediting period dates conflict across monitoring reports (2019–2029 vs 2009–2031), raising concerns about period alignment and eligibility boundaries.
- Safeguards, FPIC, grievance mechanism, and benefit-sharing are inconsistently reported across monitoring reports, increasing social-risk uncertainty.

Cosa migliorerebbe questo punteggio
- Publish a reconciliation note mapping each ER figure (78,402; 349,762; 811,737) to specific monitoring periods, issuance events, and document versions, and correct any superseded documents on the registry.
- Provide a clear, consistent grid emission factor derivation (data sources, year(s), calculation steps) and confirm which value was applied for each monitoring period, with VVB confirmation.
- Clarify and standardize the crediting period dates across all project documents and registry entries, including an explanation for any renewal or re-registration.
Questi suggerimenti indicano quali prove pubbliche aggiuntive potrebbero migliorare il livello di confidenza di questa valutazione. Non garantiscono un punteggio futuro più alto.
