Analysis

A CDM biogas-reuse project in Thailand with VVB-confirmed additionality and a measured project-specific baseline, but burdened by 12 material findings, 20 corrective action requests, and multiple cross-document contradictions on leakage, baseline characterisation, and crediting period. The project delivered roughly 213% of the pro-rata ERR expectation for the 2016–2019 monitoring window, suggesting a conservative baseline, yet key parameters (FNRB, usage rate, CORSIA/CCP status) remain unstated, leaving residual claim-safety uncertainty.
