Analysis

A CDM N2O reduction project in Paulínia, Brazil, with a VVB-verified investment additionality test and a recognised methodology (AM0021 v3.0), but undermined by a corrective action requiring correction of an erroneous GWPN2O emission factor, unresolved contradictions in ERR figures across documents, and the absence of a verified ERR figure in the available record. The project is technology-based with no carbon-stock reversal risk, and leakage is described as quantified, though the specific deduction percentage is not stated.
