Gansu Hui County Muge Swine Farm Manure Management System GHG Mitigation Project

Integrity

Additionality was confirmed by the VVB using a combined test (stated in project verification/monitoring documentation). The project uses a project-specific baseline under ACM0010 v08.0 which is less robust than a jurisdictional baseline and there is no baseline reassessment date found. No buffer pool percentage or reversal events are disclosed in the available records, increasing permanence risk. These gaps lower the integrity score despite VVB confirmation of additionality.

Transparency

The monitoring report (2023-10-15) provides a clear monitoring period (2021-06-01 to 2023-01-31) and a verified issuance figure of 58,604 tCO2e. The VVB is named (CTI Certification Co., Ltd.) and 10 documents were used. However, several key inputs are not found in the extracted record (grid emission factor, total ERR claimed, and CORSIA/CCP status), reducing transparency.

Claim Safety

The project follows approved methodology ACM0010 v08.0 and the monitoring report quantifies emissions reductions, which supports claim validity. But the contradiction on leakage treatment — monitoring report states leakage is quantified while the validation report indicates leakage was not addressed — raises over-crediting risk. Additionally, absence of usage rate assumptions and national FNRB values increases uncertainty in claims.

Documentation

Documentation is relatively complete: evidence list includes the PDD, validation report, monitoring report, and issuance, with high extraction confidence and the VVB identified. There are no material findings or corrective actions listed in the extracted records. Remaining documentation gaps include missing baseline reassessment date, buffer pool percentage, and several null fields (grid EF, CORSIA/CCP status).

Overall

I privileged the monitoring report's leakage statement (quantified) when scoring because the monitoring report provides the project-level measurement calculations and is the document that would implement leakage adjustments; it is also part of the monitoring/issuance chain. However, the validation report (dated one day later) states leakage was not addressed — this contradiction undermines data reliability. Because of that inconsistency, I adjusted integrity and claim safety downward to reflect reduced confidence in leakage treatment and potential over-crediting. Note: min_extraction_confidence is high, so extraction quality did not drive the downgrade; the downgrade reflects substantive disagreement between key documents.
