Score Breakdown

Integrity

verified The validation/verification record indicates additionality was confirmed by the VVB using an investment test (validation report, 2022-12-16).

missing Baseline and leakage robustness are weakened by missing reassessment timing and conflicting leakage treatment (monitoring report, 2022-12-15; validation report, 2022-12-16).

Transparency

verified The monitoring period is clearly stated (2021-12-01 to 2022-05-31) and the VVB is identified (monitoring report, 2022-12-15).

missing Core quantification inputs and outputs are incomplete/unclear in the extracted record (e.g., grid emission factor not found; total ERs claimed not found) and ER totals conflict across documents.

Claim Safety

verified The project is explicitly not CORSIA-eligible, reducing one channel of downstream claim risk (registry/eligibility record).

missing Over-crediting risk is elevated due to the large contradiction in verified ERs and unclear leakage handling (validation reports, 2022-10-17 vs 2022-12-16; monitoring report, 2022-12-15).

Documentation

verified Multiple document types were available and extraction confidence is high (10 documents; validation, monitoring, issuance).

missing Several social/safeguards fields conflict between monitoring and issuance records, indicating internal inconsistency (monitoring report, 2022-08-18/2022-12-15 vs issuance, 2022-11-13).

Detailed Analysis

Integrity

Additionality appears reasonably supported because the validation report (2022-12-16) confirms an investment test and VVB confirmation is indicated. Baseline setting is project-specific (ACM0002 v20.0) and the extracted record does not show when the baseline was last reassessed, which weakens robustness. Leakage is a key weakness: the monitoring report (2022-12-15) indicates leakage was not addressed, while the validation report (2022-12-16) indicates leakage was quantified, creating uncertainty about whether any deduction was applied. No material findings or corrective actions are reported, which is positive for procedural integrity (monitoring/verification record).

Transparency

The monitoring report (2022-12-15) clearly states the monitoring period (2021-12-01 to 2022-05-31) and identifies the VVB as LGAI Technological Center, S.A. (Applus+ Certification). However, key calculation inputs such as the grid emission factor and its reference year were not found in the extracted record, limiting reproducibility. The extracted record also lacks the total ERs claimed, and the verified ER figure is inconsistent across validation reports, reducing confidence in public MRV clarity.

Claim Safety

CORSIA eligibility is explicitly false, which reduces the risk of high-profile aviation claims based on these credits. Nonetheless, the contradiction in verified ERs (48,321 in the 2022-12-16 validation report versus 541,324 in the 2022-10-17 validation report) is large enough to materially affect buyer claims and suggests a heightened risk of misstatement or document/version confusion. Unclear leakage treatment (monitoring report says not addressed; validation report says quantified) further increases the risk that credited reductions could be overstated.

Documentation

Documentation coverage is relatively strong: multiple document types are present (validation, monitoring, issuance) and the minimum extraction confidence is high, suggesting the underlying files were readable. Still, internal consistency is an issue: issuance (2022-11-13) conflicts with monitoring reports on whether safeguards were mentioned, whether FPIC was conducted, and whether benefit sharing was described (monitoring report, 2022-08-18/2022-12-15). The crediting period start date also conflicts between monitoring reports (2009 vs 2019), indicating version control or reporting errors that reduce documentation reliability.

Overall

I privileged the more recent documents where applicable (e.g., the 2022-12-15 monitoring report over the 2022-08-18 monitoring report for the crediting period, and the 2022-12-16 validation report over the 2022-10-17 validation report for the verified ER figure) because later versions typically reflect corrections and finalization. However, the magnitude of the ER contradiction (48,321 vs 541,324) is so large that it materially undermines confidence even if the later figure is used, and it drives down integrity and claim-safety scores. For safeguards/FPIC/benefit sharing, I treated the monitoring report statements as more substantive than the issuance record’s boolean-style entries, but the inconsistency itself still reduces documentation and transparency scores. Gate rules to note: documentation is above 3.0 and integrity is above 4.0, so no automatic caps would be triggered post-scoring.

Audit Analysis

This VCS wind project has VVB-confirmed additionality and no reported material findings, which supports basic credibility. However, key baseline and leakage details are missing or inconsistent across documents, and there is a major discrepancy in verified ERs that increases over-crediting and reliability risk.

Project Description

Proponent: Chongli Construction Investment Huashi Wind Energy Co., Ltd Protocol categories: Energy industries (renewable/non-renewable sources) Protocols: ACM0002 Estimated annual GHG reductions: 108101 tCO2e Region: Asia Registration date: 2020-04-06

Red Flags

  • Large contradiction in verified emission reductions between two validation reports (48,321 vs 541,324), creating significant reliability/over-crediting risk.
  • Leakage treatment is inconsistent: the monitoring report says leakage is not addressed, while the validation report says leakage was quantified.
  • Crediting period start date is inconsistent across monitoring reports (2019 vs 2009), raising concerns about project timeline clarity.

Cosa migliorerebbe questo punteggio

  • Publish/clarify the final verified ER total for the monitoring period and explain the 48,321 vs 541,324 discrepancy with a document version history or VVB clarification letter.
  • Provide a clear leakage assessment consistent across validation and monitoring (including whether a leakage deduction was applied and the quantified value, if any), and disclose the grid emission factor and reference year used for calculations.

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