Sonnenerde PyroDry

Integrity

The project is assessed under Puro.earth General Rules 3.1 and the Biochar Methodology (version 2), and the verification report (2024-12-12) reports no material findings and no corrective actions. However, the extracted record does not include the additionality test type or confirmation that additionality was verified by the VVB, and it also lacks any stated baseline method or baseline reassessment timing. Leakage treatment is also not found (no deduction percentage and no justification), and permanence risk controls such as a buffer pool contribution or any reversal-event reporting are not found in the extracted record.

Transparency

Transparency is helped by the presence of a named VVB (bio.inspecta AG) and a clearly stated monitoring period (2023-12-20 to 2024-03-31) in the verification report (2024-12-12). But the extracted record does not provide the claimed or verified total net removals for the period, preventing a basic reconciliation of issuance quantities. Key MRV descriptors such as the fossil/non-fossil determination method and usage monitoring method were also not found in the extracted record.

Claim Safety

Claim safety is constrained because the extracted record does not include the baseline method, leakage justification, or any quantified leakage deduction, all of which are central to avoiding over-crediting in biochar systems. The extracted record also does not state CCP status or CORSIA eligibility, so buyers cannot easily assess how the credits might be marketed across integrity labels or aviation claims. With verified removal totals not found in the extracted record, it is difficult to substantiate precise claims about the volume of removals for the monitoring period.

Documentation

Documentation quality is mixed: the extracted record indicates four documents were used and includes a recent verification report date (2024-12-12) and the VVB name. However, the evidence document list is not specific (shown as "unknown"), and many core quantitative and methodological fields were not found in the extracted record. The minimum extraction confidence is medium, which supports some reliance but still warrants caution given the number of missing integrity-critical details.

Overall

There are no listed contradictions between documents in the extracted record, so no cross-document discrepancies needed to be resolved. The main limitation is breadth of missing integrity and MRV information (additionality, baseline, leakage, permanence/buffer, and verified removal totals), which materially reduces confidence in both over-crediting controls and buyer-facing claims. Scores are therefore held in the mid-to-low range despite a recent verification and the absence of reported findings.
