Drobonso Carbon
Audit Analysis
Drobonso Carbon is a pre-implementation biochar production and storage project under the Isometric standard with a 200-year permanence claim and a lifetime ex-ante estimate of 311 tCO₂e. The project presents a reasonable methodology and no adverse findings, but critical verification gaps remain: no VVB has verified additionality, no buffer pool is documented, and only a PDD is available with no verification or monitoring reports. The project is in an early stage (crediting period begins 2026), which explains some gaps, but the absence of independent verification is a material concern.
Red Flags
- Additionality test (combined investment/regulatory) is described in the PDD but has not been verified by any VVB; no VVB name appears in the extracted record
- No buffer pool percentage is stated despite a 200-year permanence claim, leaving reversal risk unmitigated in the documentation
- Only a single document (PDD) is available; no verification report, monitoring report, or independent audit is present in the record
