Biomass Briquette Based Earth Stove Project

Integrity

The monitoring report states that additionality was confirmed by the VVB and that a combined additionality test was used, which supports the project’s core integrity case. On the other hand, baseline reassessment is not stated, buffer pool coverage is not found, and reversal events are marked as not addressed, so permanence and baseline robustness are only partly evidenced. The quantified leakage deduction of 10% is a positive sign, but the contradiction with the PDD’s zero or negligible leakage treatment weakens confidence in the underlying assumptions.

Transparency

Transparency is moderate because the extracted record includes a monitoring report with a defined monitoring period and quantified leakage treatment. However, the VVB name is not stated, and the verified versus claimed emission reduction totals are not available in the extracted record, limiting auditability. The absence of a clearly stated FNRB method and verified usage rate also leaves important MRV elements incomplete.

Claim Safety

Claim safety is mixed. The later monitoring report’s 10% leakage deduction is more conservative than the PDD’s earlier negligible or zero leakage position, so I privileged the monitoring report because it is more recent and reflects monitored performance. Still, the project is marked CORSIA-eligible and CCP status is not stated, which leaves some residual dual-claim and market-claim uncertainty.

Documentation

Documentation quality is fair but not strong. Only the PDD and monitoring report are listed as evidence documents, and the extraction confidence is medium rather than high. The monitoring report is dated 2013-09-13, but several key items such as the VVB name, buffer pool, baseline reassessment, and verified usage rate are not found in the available documents.

Overall

Overall, I privileged the monitoring report over the PDD where contradictions exist because it is later and reflects monitored project data, especially for leakage and the crediting period. Specifically, I relied on the monitoring report’s 10% leakage deduction instead of the PDD’s zero or negligible leakage treatment, and on the monitoring report’s crediting period rather than the earlier PDD range. These contradictions indicate some reliability issues, so the score is held below what the positive additionality finding alone might suggest.
