Audit Analysis
A Gold Standard biogas project in Kerala with VVB-confirmed additionality and quantified leakage, but weakened by a project-specific baseline, absence of a stated buffer pool, and a high volume of corrective actions (17 CARs/CRs) that signal recurring data-quality issues. The project delivered roughly 57% of its claimed emissions reductions for the 2019–2021 monitoring period, which is conservative but suggests ex-ante estimates were optimistic. CORSIA eligibility introduces a dual-channel risk that is not fully mitigated in the available documentation.
Red Flags
- 17 corrective actions and comments (12 CARs, 5 CRs) were raised during verification, including an inconsistency in fire-wood consumption reporting between the emission reduction worksheet and the monitoring report, indicating recurring data-quality weaknesses.
- CORSIA eligibility is confirmed while CCP status is not mentioned, creating an unresolved dual-channel / double-claiming risk.
- The FNRB method is contradictory across documents: the verification report (2017) states a local field measurement while the monitoring report (2023) references a national default, undermining confidence in the emission factor applied.
- No buffer pool percentage is stated in any available document, leaving permanence risk unquantified for a biogas project where digester failure or abandonment could reverse credits.
