Gansu Ganzhou Biogas Recovery and Utilization Project

Integrity

The project uses a project-specific baseline approach (baseline described as project-based in the extracted record), and the timing of any baseline reassessment is not stated in available documents, which weakens baseline robustness. Additionality is confirmed by the VVB (validation/assurance documentation referenced), supporting integrity, but the specific additionality test type is not found in the extracted record. Leakage treatment is a key weakness: the extracted record indicates leakage is not addressed and provides no leakage deduction, which increases the risk of over-crediting for a waste/biogas activity.

Transparency

The monitoring report (dated 2023-12-01) clearly states the monitoring period (2021-08-01—2022-12-31) and the verified emission reductions (10,156 tCO2e), which supports MRV transparency. However, the total emission reductions claimed are not found in the extracted record, preventing a straightforward claimed-versus-verified comparison. Important calculation inputs such as the grid emission factor and the grid EF year are also not found, limiting third-party reproducibility from the extracted dataset.

Claim Safety

No material findings are reported, and the monitoring/assurance documentation notes that 7 CARs and 6 CLs were raised and successfully closed, which reduces the likelihood of unresolved MRV issues. At the same time, leakage is not addressed in the extracted record (no justification and no deduction stated), which elevates over-crediting and greenwashing risk for buyers. CORSIA eligibility and CCP status are not stated in available documents, so buyers cannot rely on these labels for higher-integrity claims based on the extracted record alone.

Documentation

Documentation coverage is relatively strong: the extracted record references a PDD, validation report, and monitoring report, with 10 documents used and high extraction confidence. The presence of safeguards-related elements (FPIC, grievance mechanism, and benefit-sharing described) indicates that non-carbon documentation exists beyond pure quantification. Nonetheless, some key quantified fields are missing from the extracted record (e.g., total ERs claimed, grid EF/year), and one evidence document is categorized as 'unknown', indicating remaining completeness/traceability gaps.

Overall

There are no listed contradictions between documents in the extracted record, so no cross-document discrepancies needed to be resolved or privileged. Overall quality is mid-range: VVB-confirmed additionality, closed CARs/CLs, and stated verified ERs support credibility, but missing baseline reassessment timing, missing key quantification inputs, and an absence of leakage treatment materially increase uncertainty. Note: if documentation were to score below 3.0, transparency would be capped post-scoring; and if integrity were below 4.0, the overall score would be capped at 6.0 (gate rules applied outside this output).
