Cgn Inner Mongolia Zhurihe Phase I Wind Farm Project
Score Breakdown
Integrity
verified Additionality is confirmed by the VVB using an investment test (validation report).
missing Leakage is not addressed and no leakage deduction is stated in the extracted record (monitoring report).
Transparency
verified Key MRV elements are present (method ACM0002 v20.0, monitoring period 2019-03-04—2021-12-31, grid emission factor 1.0548) in the monitoring report (2022).
missing Conflicting emissions figures across validation documents reduce confidence in reported outcomes (validation reports 2013 vs 2022).
Claim Safety
verified The project is explicitly not CORSIA-eligible, reducing some double-claiming channel risk (registry record).
missing Contradictory credited/verified ER figures (256,089 vs 80,706) elevate over-crediting and marketing-claim risk (validation reports 2013 vs 2022).
Documentation
verified A relatively complete document set is referenced (PDD, monitoring report, validation report, issuance) with 27 documents used and high extraction confidence.
missing Corrective action(s) were required to revise project coordinates and methodology version, indicating documentation control issues (monitoring/verification record, 2022).
Detailed Analysis
Integrity
The validation documentation indicates additionality was assessed via an investment test and confirmed by the VVB (validation report). The baseline is project-specific under ACM0002, but the extracted record does not show when the baseline was last reassessed, which weakens robustness over time (monitoring report, 2022). Leakage is explicitly not addressed and no leakage deduction is stated, which is a material gap even for grid-connected wind where leakage is often argued negligible but should be justified (monitoring report, 2022).
Transparency
The monitoring report (2022-09-01) provides a clear monitoring period (2019-03-04—2021-12-31) and a stated grid emission factor (1.0548), supporting traceability of calculations. However, the extracted record shows a major inconsistency in reported verified emission reductions between validation documents (2013 vs 2022), which undermines transparency and comparability of results. No usage monitoring method is applicable/needed for this grid electricity project, but the absence of a stated grid EF year reduces reproducibility (monitoring report, 2022).
Claim Safety
The project is marked as not CORSIA-eligible, which reduces the risk of dual-channel claims through CORSIA (registry record). Nonetheless, the large discrepancy in emission reduction figures across validation documents (256,089 vs 80,706) increases the risk that public claims could be overstated or confusing to buyers (validation reports 2022-09-02 vs 2013-12-30). CCP status is not found in the extracted record, so buyers cannot rely on that screening signal here.
Documentation
The extracted record indicates a broad evidence base (PDD, monitoring report, validation report, issuance) and a relatively high document count (27) with high extraction confidence, which supports document completeness. At the same time, the monitoring/verification record notes corrective action(s) to revise project coordinates and the methodology version in the PDD and monitoring report, indicating prior inconsistencies in core project descriptors (monitoring report, 2022). Contradictions across different dated monitoring reports on safeguards/FPIC/grievance also suggest uneven documentation over time.
Overall
I privilege the more recent documents where they appear to reflect updated project status: for safeguards/FPIC/grievance/benefit sharing, I rely on the 2022 monitoring report over the 2013 monitoring report because it is later and likely reflects current practices, but the contradiction still lowers confidence. For the crediting period, I privilege the 2022 monitoring report (2019–2029) over the 2021 monitoring report (2009–2019) because it aligns with the stated monitoring start date (2019-03-04), yet the inconsistency is significant and reduces reliability. For the emissions reduction figures, I treat the discrepancy between the 2013 and 2022 validation reports (80,706 vs 256,089) as a major red flag; without a clear reconciliation in the extracted record, this uncertainty drives down integrity, transparency, and claim-safety scores.
Audit Analysis
This VCS wind project has VVB-confirmed additionality (investment test) and uses the standard ACM0002 methodology, which supports baseline credibility. However, leakage is not addressed in the extracted record and there are major inconsistencies across documents on credited emissions and even the crediting period, which increases over-crediting and reliability risk.
Project Description
The CGN Inner Mongolia Zhurihe Phase I Wind Farm Project generates renewable electricity using wind power resources and sells the generated output to the North China Power Grid. This project site has an abundant wind resource and features 25 wind turbines, each with a rated power output of 2000 kW, for a total power capacity of 50 MW. The project is expected to generate an average annual emission reduction of about 130,755 tCO2e.
Red Flags
- Large discrepancy in reported verified emission reductions across documents (256,089 vs 80,706), raising data reliability and over-crediting concerns
- Leakage treatment is not addressed and no leakage deduction is stated in the extracted record
- Crediting period is inconsistent across monitoring reports (2019–2029 vs 2009–2019), creating uncertainty about eligibility and accounting boundaries

Cosa migliorerebbe questo punteggio
- Provide a clear reconciliation table explaining why emission reduction figures differ across the 2013 and 2022 validation documents, and link the final issued volume to the specific monitoring period and calculation inputs.
- Add explicit leakage assessment and justification (even if concluded negligible) with a stated leakage deduction (e.g., 0%) consistent with ACM0002 requirements and the 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.
