Analysis

This CDM N2O decomposition project at a nylon chemical plant in China uses a recognised methodology (AM0021 v3) and was validated by DNV, but the available documents show significant gaps: additionality assessment details are absent, the leakage justification is contradictory between the validation and monitoring reports, and five material findings (CARs) were raised against the PDD. The project's 7-year crediting period (2014–2021) has elapsed, yet no verified ERR figure is available in the record, limiting confidence in actual delivery.
