Analysis

A Gold Standard methane recovery and biogas cogeneration project in Vietnam with a VVB-confirmed investment additionality test and no reversal events, but undermined by a project-specific modeled baseline, a thin 0% leakage justification, and a verification report that surfaced ten or more corrective actions including a grid emission factor error and methodology version mismatch. The project is CORSIA-eligible with CCP status unstated, creating dual-channel risk, and multiple contradictions across documents (crediting period, baseline type, FPIC status) reduce confidence in the data record.

  • Removal or reduction

    Emission reduction or avoidance

    Prevents or reduces emissions — fits contribution claims, not SBTi neutralisation.

  • Paris Agreement (Article 6)

    Not published

    This registry does not publish Article 6 authorizations.
