GS1247 VPA 63 Improved Kitchen Regimes: Kayonza District Borehole Project, Rwanda

Integrity

The monitoring report indicates a project baseline and a quantified leakage treatment, which supports some methodological discipline. At the same time, additionality test type is not stated and additionality is not confirmed by the VVB in the extracted record, which weakens the integrity assessment. The report also notes a temporary breakdown of borehole KAY039 in 2017 and says those dates were deducted from crediting, but reversal risk is otherwise not clearly managed and no buffer pool is shown.

Transparency

The monitoring report gives a clear monitoring period and says usage was monitored through annual surveys, which helps traceability. However, total claimed and verified emission reductions are not stated, and the VVB name is not found in the extracted record. The absence of registry-level completeness details limits confidence in public-facing transparency.

Claim Safety

Claim safety is supported somewhat by the quantified leakage treatment and the fact that the monitoring report documents a deduction for the temporary borehole breakdown. But the baseline is project-specific, the usage rate is inconsistent across documents, and the leakage justification is contradicted by the PDD, which weakens confidence in the claimed climate benefit. CORSIA eligibility is not stated and CCP status is only noted as not mentioned, so dual-claim risk is not fully resolved.

Documentation

The record draws on a PDD and monitoring report, and the extraction confidence is high, which is a positive sign. Even so, the VVB name is missing, and the crediting period differs between monitoring documents, suggesting incomplete or inconsistent documentation. No material findings or corrective actions were reported, which is positive, but the overall documentary package still has notable gaps.

Overall

I privileged the more recent monitoring report from 2021 over earlier documents where the extracted record showed contradictions, because it is the latest available source and includes updated monitoring results. Specifically, I relied on the 90% verified usage rate and the quantified leakage treatment from the 2021 monitoring report, while noting that the PDD and earlier monitoring report conflict on usage rate, leakage handling, reversal reporting, and crediting period. Those contradictions reduce reliability and justify a cautious overall score.
