Chantaburi Starch Wastewater Treatment and Biogas Utilization Project

Audit Analysis

A CDM biogas/methane-avoidance project in Thailand with a 7-year crediting period (2018–2025) and a claimed lifetime of 269,346 tCO₂e. The project lacks verified monitoring data, a stated additionality test type, and a quantified leakage assessment, and two material findings (missing monitoring equipment, adjusted flare efficiency) remain as open corrective actions. The project-specific modeled baseline and the contradiction between the PDD and validation report on leakage treatment further weaken confidence in the credit claims.

Project Description

Red Flags

• ⚠No verified ERR or monitoring period data available in the extracted record — the 269,346 tCO₂e claim is entirely unverified.
• ⚠Leakage treatment contradicts between the PDD (quantified) and the validation report (deemed negligible), with a 0% deduction applied.
• ⚠Additionality test type and VVB confirmation are not stated in the extracted record despite the project passing validation.
• ⚠Monitoring equipment for QHFO,y and Qoil,h was not installed at the time of the site visit (validation report, Jan 2020); corrective action deadline was June 2020 with no confirmation of completion.
• ⚠Flare efficiency was adjusted to 80% due to lack of sizing details for the enclosed flare, introducing estimation uncertainty.
