Audit Analysis
A Gold Standard biogas-to-electricity project on a swine farm in China with confirmed additionality and in-place safeguards, but undermined by 15 corrective actions flagging widespread monitoring and data-quality gaps, a project-specific modeled baseline with no stated buffer pool, and a 26% downward revision of the verified ERR between two verification reports. The project delivered roughly 137% of its pro-rata expectation for the five-month monitoring window, which is encouraging, but the volume of unresolved monitoring deficiencies casts doubt on the reliability of the underlying data.
Red Flags
- 15 corrective actions required in the verification report (2023-03-31), spanning missing cross-checks, uncalibrated meters, unrecorded emergency procedures, and parameters not monitored as specified in the PDD
- Verified ERR revised downward from 334,691 tCO₂e (verification report, 2022-12-20) to 245,755 tCO₂e (verification report, 2023-03-31), a 26% reduction indicating the initial verification was too generous
- Leakage deduction percentage not stated despite the justification being labelled 'quantified'; the actual figure is absent from the extracted record
