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 (named VVB, monitoring period 2018-07-21 to 2020-12-31, grid emission factor 1.0549 with reference year 2008) (monitoring report).

missing Conflicting ER/ERR and crediting-period figures across documents reduce transparency and traceability (monitoring and validation reports).

Claim Safety

verified The project is explicitly not CORSIA-eligible, reducing some downstream double-claiming/eligibility risk (registry record/extracted facts).

missing Contradictory claimed vs verified ER/ERR values and shifting crediting-period dates increase greenwashing and over-crediting risk (monitoring and validation reports).

Documentation

verified Document set is relatively complete (PDD, validation report, monitoring report) with 13 documents used and high extraction confidence (extracted record).

missing Safeguards and stakeholder provisions are inconsistently reported across monitoring reports (2011 vs 2020/2021), indicating documentation quality issues.

Detailed Analysis

Integrity

The validation report indicates additionality was assessed via an investment test and confirmed by the VVB (Bureau Veritas Certification), which supports additionality robustness. The project applies ACM0002 with a project-specific baseline approach and a stated grid emission factor of 1.0549 (monitoring report), but the baseline reassessment timing is not stated in the extracted record. Leakage is not addressed and no leakage deduction is stated (monitoring report), which weakens accounting completeness even for a wind project where leakage is often treated as negligible but should still be justified.

Transparency

The monitoring report provides a clear monitoring period (2018-07-21 to 2020-12-31), identifies the VVB (Bureau Veritas Certification), and reports the grid emission factor and reference year (monitoring report). However, the extracted record shows major inconsistencies in reported claimed and verified ER/ERR values across monitoring/validation documents, reducing traceability of what was actually issued/verified. Safeguards-related disclosures also vary across monitoring reports (2011 vs 2020/2021), which reduces confidence in consistent reporting over time.

Claim Safety

CORSIA eligibility is explicitly false, which reduces the risk of dual-channel claims tied to CORSIA (extracted record). Nonetheless, the magnitude of discrepancies between claimed and verified ER/ERR figures across documents creates a material over-crediting/greenwashing risk because users cannot easily reconcile which number is authoritative. The baseline is project-specific and the baseline reassessment date is not found in the extracted record, adding uncertainty around whether the baseline inputs remain appropriate over time.

Documentation

The extracted record indicates 13 documents were used and extraction confidence is high, supporting a relatively strong documentation score. Core documents are present (PDD, validation report, monitoring report), and no material findings or corrective actions are reported (validation/monitoring record). However, safeguards, grievance mechanism, FPIC, and benefit-sharing are inconsistently stated across monitoring reports from different years, which suggests uneven documentation quality and version control.

Overall

I privileged the more recent documents when contradictions occurred, because later monitoring/validation reports typically supersede earlier versions and reflect updated project status. For claimed ER/ERR, I treated the 2020 monitoring report figure (635,270) as the current claimed value over the 2011 monitoring report (122,925), but I discounted confidence due to the large unexplained gap. For verified ER/ERR, I privileged the 2021 validation report value (229,587) over the 2020 validation report value (635,270) because it is more recent and likely reflects the final verification outcome; this contradiction materially lowers integrity and claim-safety scores. For safeguards/FPIC/grievance/benefit-sharing, I accepted the later monitoring reports indicating these are present, but the inconsistency with the 2011 monitoring report reduces transparency and documentation reliability. For the crediting period, I privileged the 2021 monitoring report (2019–2028) as the latest statement, but the conflicting 2020 monitoring report (2009–2018) is a significant red flag that depresses overall scoring.

Audit Analysis

This is a VCS wind power avoidance project using ACM0002 with additionality confirmed by the VVB and no reported material findings. However, key accounting elements (notably leakage treatment) are not addressed in the extracted record, and multiple cross-document inconsistencies—especially around ER/ERR figures and the crediting period—raise reliability and over-crediting concerns.

Project Description

The Inner Mongolia Jingneng Saihan Wind Farm Phase I Project is a renewable energy project that generates electricity through a wind farm with a total capacity of 49.5 MW and a 220 kV substation. The project sells the electricity generated to West Inner Mongolia Power Grid, while reducing an average of 131,331 tCO2e annually.

Red Flags

  • Large inconsistencies in claimed and verified emission reductions across documents (e.g., 635,270 vs 122,925 claimed; 229,587 vs 635,270 verified) create over-crediting and data reliability risk.
  • Crediting period is inconsistent across monitoring reports (2019–2028 vs 2009–2018), which can affect eligibility and the interpretation of monitoring results.
  • Leakage is not addressed and no leakage deduction is stated in the extracted record, despite being a core accounting element to document explicitly.

Cosa migliorerebbe questo punteggio

  • Provide a reconciled ER/ERR table that clearly links claimed vs verified totals to the same monitoring period and explains why earlier documents show different totals.
  • Clarify and evidence the correct crediting period (start/end dates) and ensure all public documents and registry entries are consistent.
  • Explicitly document leakage treatment under ACM0002 (even if negligible) and state the leakage deduction applied (e.g., 0% with justification).

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