Shuangbaotai Animal Manure Management System GHG Mitigation Project in Guangxi Province

Integrity

The project benefits from a VVB-confirmed additionality assessment and a combined additionality test, which supports the baseline and project rationale. Still, reversal handling is weakly documented: reversal events are marked as not addressed, buffer pool coverage is not stated, and the record includes several verification findings with corrective actions required. Leakage is at least acknowledged as quantified, but the absence of a stated deduction percentage limits confidence in the robustness of the crediting approach.

Transparency

The monitoring period and VVB identity are available, and the project is tied to Gold Standard documentation, which helps traceability. However, total emissions reductions claimed and verified are not stated, and important MRV details such as usage monitoring and FNRB inputs are missing from the extracted record. The low extraction confidence further reduces transparency because at least one key document was poorly readable.

Claim Safety

Claim safety is weakened by missing quantitative evidence on usage rates, FNRB, and verified emissions reductions, all of which are important for biogas electricity projects. The project is marked CORSIA-eligible, while CCP status is not stated, so dual-claim risk cannot be ruled out from the available record. Leakage being quantified is a positive, but the contradictory period information and unresolved reversal treatment increase the risk of over-crediting.

Documentation

The evidence base includes multiple official documents, including a PDD and monitoring report, and the project documents safeguards such as FPIC, grievance mechanisms, and benefit sharing. Even so, the extraction confidence is low, one document source is unknown, and several fields are not stated in available documents. The presence of three corrective action requests also suggests the documentation package was not fully clean at verification.

Overall

Overall confidence is moderate to low because the project has some strong procedural elements but also important reliability issues. I privileged the more recent monitoring-report information where it appeared to be the later source, but the contradiction on the crediting period remains unresolved because both dates come from monitoring reports and the record does not explain the discrepancy. I also treated the reversal-event inconsistency conservatively: one source says not addressed, while another later record suggests none reported, so the safer interpretation is that reversal treatment is not clearly documented.
