Analysis

This Gold Standard household biogas PoA in Sichuan has a VVB-confirmed additionality assessment and a recently reassessed baseline, but is undermined by a very large volume of material findings and corrective actions (31 items), including incorrect emission-reduction calculations in the first monitoring report. The verified emission reductions for a single monitoring period (142,048 tCO₂e) exceed the entire lifetime ex-ante estimate (100,610 tCO₂e), raising serious over-crediting concerns. No buffer pool or reversal-risk treatment is documented, and several key parameters (FNRB, CORSIA eligibility, CCP status) are absent from the record.
