Catalytic N2O Abatement Project in the tail gas of the Caprolactam production plant in Thailand

Audit Analysis

A CDM N2O abatement project in Thailand's caprolactam sector with VVB-confirmed additionality and a measured project-specific baseline, but weakened by the absence of a buffer pool, a 0% leakage deduction supported by contradictory justifications across monitoring reports, and a notable gap in verified ERR figures. The project's documentation is reasonably complete (12 sources, high extraction confidence) yet lacks grievance mechanisms, FPIC, and safeguards documentation, and the PDD required seven material corrections at validation.

Project Description

Red Flags

• ⚠Leakage justification is contradictory: the 2013 monitoring report states 'quantified' while the 2012 report states 'deemed negligible', yet the deduction is 0% in both cases — a quantified result of zero is unusual and the inconsistency undermines confidence in the leakage assessment.
• ⚠No buffer pool is recorded for permanence risk, and no reversal events are confirmed either way; for a catalytic abatement unit, catalyst degradation or unplanned shutdown could reverse credits with no safety net.
• ⚠Total ERR verified is not stated in any available document; only the claimed figure (10,288 tCO2e) is available, leaving the actual verified reduction unconfirmed.
• ⚠Safeguards, FPIC, and grievance mechanism are all absent or explicitly false in the later monitoring reports, despite the validation report (2009) having mentioned safeguards — a regression in documented social compliance.
