Audit Analysis
A Gold Standard landfill-gas-to-power project in China with VVB-confirmed additionality and a legally mandated capture obligation, but undermined by a significant grid emission factor discrepancy between the verification and monitoring reports, a project-specific modeled baseline, and the absence of key operational parameters such as FNRB values, usage rates, and an LCA. The claimed and verified ER figures match exactly at 107,303 tCO₂e for the 2023 monitoring period, but the underlying data inconsistencies and missing sustainability documentation limit confidence in the robustness of the credit.
Red Flags
- Grid emission factor differs by 52% between the verification report (0.8587 tCO₂/MWh) and the monitoring report (0.57025 tCO₂/MWh), both dated 2023-11-28, creating material uncertainty in the ER calculation
- Leakage justification is inconsistent: the verification report describes it as 'quantified' while the monitoring report labels it 'deemed negligible', despite a 0% deduction in both cases
- Free, Prior and Informed Consent (FPIC) was not conducted, despite the project operating on a municipal landfill site in a populated area
- No FNRB value, usage rate, or LCA is reported in any available document, leaving the biogas-to-electricity conversion chain partially unverified
