Boomitra Grassland Restoration in East Africa Through Soil Enrichment

Integrity

Additionality is supported: the validation report documents a barrier test and confirms additionality (validation_report, 2025-07-01). A 15% buffer pool is specified which supports permanence. However, leakage treatment is reported as not addressed in the validation report and reversal events are not documented, which are material weaknesses for an AFOLU soil-carbon project. The baseline is project-specific and not shown to have been recently reassessed, weakening baseline robustness.

Transparency

Transparency is partial: the VVB is named (Earthood Services Limited) and a monitoring period is provided (2019-04-01 — 2022-03-01), and the validation report is recent (2025-07-01). However, key MRV metrics such as total emissions/removals claimed and verified, usage monitoring method, and error/uncertainty figures are not found in the extracted record, reducing verifiability.

Claim Safety

There is a moderate risk of over‑claiming. The project uses a project-specific baseline without evidence of recent reassessment, and leakage justification is either absent or contradicted by another document. The buffer pool helps reduce reversal risk, but unaddressed reversal events and missing MRV figures leave claim safety uncertain. CORSIA/CCP double-claim status is not stated, so double-claim risk cannot be ruled out.

Documentation

Documentation is moderate: ten documents were used and a recent validation report (2025) is available, and safeguards (FPIC and grievance mechanism) and benefit sharing are described. Extraction confidence is medium and one evidence document is listed as 'unknown', indicating gaps in provenance and lowering confidence in completeness.

Overall

I privileged the validation report (validation_report, 2025-07-01) when resolving contradictions because it is a known, higher-priority document with a named VVB; the PDD is older (2022) and one contradictory source is of unknown provenance. Specifically: (1) leakage: the validation report states leakage is not addressed while an unknown later document claims leakage is deemed negligible; I gave priority to the validation report due to traceable provenance, which lowers the leakage and integrity assessment. (2) crediting period: the validation report gives 2019-01-10 — 2039-01-09 while the PDD gives 2018-08-01 — 2038-07-31; I privileged the more recent validation report. These contradictions and the medium extraction confidence reduce the project score — they indicate record reliability issues and missing MRV numbers that prevent a higher rating.
