Hebei Chengde Weichang Yudaokou Pasture 150MW Wind Farm Project

Integrity

Additionality appears reasonably supported because the validation/verification process confirms an investment test, and the monitoring record (2023-08-31) reports no material findings. The baseline is project-specific under ACM0002, but the extracted record does not state when the baseline was last reassessed, which is an evidence gap for baseline robustness. Integrity is further weakened by inconsistent quantification inputs across validation reports (notably the grid emission factor) and inconsistent leakage treatment between the validation report (2016-05-20) and the monitoring record (2023-08-31).

Transparency

The monitoring record (2023-08-31) provides a clear monitoring period (2021-12-01 — 2022-05-31) and shows the same total for claimed and verified emission reductions (273,055 tCO2e), which supports MRV clarity for that period. However, the same monitoring record lists corrective actions, including adding a comparison table of estimated vs achieved reductions and clarifying compliance with the registered monitoring plan regarding a 10kV backup line. These issues reduce transparency because they indicate the reporting package was incomplete or required clarification during review.

Claim Safety

The project is marked as not CORSIA-eligible in the extracted record, which lowers the risk of high-profile aviation claims. Nonetheless, claim safety is constrained by over-crediting risk signals: validation reports disagree on the grid emission factor (0.8269 vs 1.05485) and on the verified ER total (273,055 vs 136,337), both of which can materially affect credited outcomes. Leakage is also problematic: the monitoring record (2023-08-31) shows a 0% leakage deduction while stating leakage was not addressed, conflicting with the validation report (2016-05-20) that indicates leakage was quantified.

Documentation

Documentation coverage is relatively strong: the extracted record references a PDD, monitoring report, validation report, and issuance, with 41 documents used and high extraction confidence. However, the presence of multiple contradictions across documents (safeguards and stakeholder process disclosures, crediting period dates, grid emission factor values, and verified ER totals) indicates inconsistent documentation over time. Corrective actions in the monitoring record (2023-08-31) also suggest the submitted documentation required supplementation and clarification.

Overall

Overall scoring is pulled down primarily by internal inconsistencies across official documents, which reduce confidence in quantification and stakeholder-process claims. For the leakage justification contradiction, the 2023 monitoring record is privileged over the 2016 validation report because it is more recent and should reflect the monitoring-period treatment; this inconsistency lowers integrity and claim safety. For safeguards/FPIC/grievance/benefit-sharing contradictions, the 2023 monitoring record is privileged as the latest disclosure, but the earlier 2016 monitoring report conflicts, so safeguards confidence is discounted. For the verified ER total and grid emission factor contradictions, the more recent validation report values (2024-07-18) are privileged over older validation reports, but the magnitude of the discrepancies indicates reliability risk and drives a conservative overall score. For the crediting period contradiction, the 2023 monitoring record is privileged as the latest, but the mismatch with the 2021 monitoring report suggests registry/record inconsistency and reduces documentation confidence. (Gate rules note: integrity is above 4.0 and documentation is above 3.0, so no deterministic caps would apply.)
