Sichuan Rural Poor-Household Biogas Development Programme, CPA Nb. SCHHBG-2010-01

Audit Analysis

The Sichuan Rural Biogas Programme is a long-running Gold Standard project with 73 component households, confirmed additionality, and no reported reversal events. However, the project-specific baseline, absence of a buffer pool, contradictory leakage justifications, and an extensive catalogue of material findings and corrective actions across multiple monitoring cycles raise meaningful concerns about the robustness and consistency of the MRV process. The 2022 monitoring period shows the verified ERR matching the claimed value, but the lifetime ex-ante estimate is not available in the extracted record, limiting the ability to assess cumulative over- or under-delivery.

Project Description

Red Flags

• ⚠Leakage justification is contradictory: the 2023 verification report describes it as 'quantified' while the 2023 monitoring report calls it 'deemed negligible,' yet the deduction is 0% in both cases.
• ⚠The 2023 verification report lists over 50 material findings and corrective actions, including incorrect baseline and project emission calculations, missing sampling parameters, and outdated data sources in the monitoring report v1, indicating systemic MRV quality-control weaknesses.
• ⚠The additionality test type is inconsistent across documents: the 2013 monitoring report records a barrier test while the 2021 PDD records an investment test, and the 2014 verification report did not confirm additionality whereas the 2023 report does.
• ⚠FPIC (Free, Prior and Informed Consent) status is not stated in any available document, despite the project targeting rural poor households.
