Analysis

NetZero-003-Brejetuba is a Puro.earth biochar project with a solid VVB-verified investment additionality test and a reasonable leakage justification, but it carries notable gaps in permanence (reversal risk explicitly not addressed, no buffer pool stated) and in monitoring transparency (no FNRB method, no usage-rate data). The ERR figures across two verification reports are consistent with different monitoring periods rather than a true discrepancy, and the verified figure slightly exceeds the claimed figure, indicating no over-crediting in the latest period.
