Audit Analysis

A Gold Standard biogas project serving tsunami-affected households in India, verified by EPIC Sustainability Services. The VVB confirmed additionality via a combined test and the project over-delivered relative to its pro-rata expectation, but three material findings on baseline calculations and monitoring parameters, the absence of a stated buffer pool, and a project-specific baseline last reassessed in 2008 limit confidence in the integrity of the credit.

Red Flags

  • The verification report (2016) flagged that the baseline emission reduction calculation did not follow the PDD or methodology, and that ex-ante fixed parameters did not match the PDD — both required corrective action.
  • Seven contradictions were identified across documents, including differing crediting-period start dates (Feb 2010 vs Aug 2010) and a leakage-justification discrepancy between the verification and monitoring reports.
  • Minimum extraction confidence is rated low, indicating at least one key document was poorly readable, which undermines confidence in the completeness of the evidence base.
