Score Breakdown

Integrity

verified The verification report confirms additionality was verified by the VVB (DNV).

missing The verification report reports a material discrepancy in volumes with a 7% impact on CORCs, raising over-crediting and control-risk concerns.

Transparency

verified The VVB is identified (DNV Business Assurance Finland Oy Ab) and the monitoring period is specified (2023-01-01 to 2024-01-31) in the verification report.

missing Key quantified outputs (claimed/verified removals) and leakage treatment were not found in the extracted record.

Claim Safety

verified CCP status is listed as eligible, which can reduce some buyer-side quality concerns if substantiated by the program.

missing Baseline and leakage approach were not found in the extracted record, and a material volume discrepancy suggests non-trivial over-crediting risk.

Documentation

verified A recent verification report is available (dated 2025-03-03) and includes material findings and corrective action closure.

missing Some key fields are not found in the extracted record (e.g., baseline method, leakage, grievance mechanism), and extraction confidence is only medium.

Detailed Analysis

Integrity

The verification report (2025-03-03) indicates additionality was confirmed by the VVB (DNV Business Assurance Finland Oy Ab), which supports additionality robustness. However, the same verification report identifies a material discrepancy between reported production and shipped volumes at the Svedala site with a 7% impact on CORCs, which is a meaningful integrity risk even though it was corrected. A buffer contribution of 2.5% is stated in the extracted record, but reversal events and their management were not found in the extracted record, limiting permanence assessment for a removal credit.

Transparency

The verification report provides clear auditor identification (DNV) and a defined monitoring period (2023-01-01—2024-01-31). Still, the extracted record does not include the total removals claimed or verified, which materially reduces transparency on the core quantified outcome. Leakage deduction and justification were also not found in the extracted record, leaving an important accounting element opaque.

Claim Safety

CCP status is listed as eligible in the extracted record, which may support market acceptance, but CORSIA eligibility was not found in the extracted record, leaving some double-claim channel risk unresolved. The absence of baseline method details and leakage treatment in the extracted record increases over-crediting/greenwashing risk because buyers cannot easily evaluate conservativeness. The verification report’s 7% volume discrepancy (and subsequent correction) is a concrete indicator that credit quantities could be sensitive to data handling errors.

Documentation

A recent verification report (2025-03-03) is present and includes both a material finding and a documented corrective action (revision of CORCs calculation), which is a positive sign of audit trail and issue resolution. However, several important elements were not found in the extracted record (baseline method, leakage, grievance mechanism, FPIC), suggesting incomplete document extraction or incomplete disclosure. With medium minimum extraction confidence and evidence documents listed as unknown, documentation completeness is only moderate.

Overall

No contradictions were listed in the extracted record, so no cross-document discrepancies could be resolved or prioritized. Overall quality is moderate: third-party verification and corrective action closure are positives, but missing quantified removal totals, missing baseline/leakage details, and a material 7% volume discrepancy reduce confidence in credit accuracy. If documentation were to fall below the documentation gate threshold, transparency could be capped post-scoring (gate rule noted).

Audit Analysis

This Puro biochar removal project has third-party verification and a stated buffer contribution, but several core quantifications (baseline approach, leakage treatment, and verified removals) were not found in the extracted record. A material discrepancy in shipped vs. produced volumes was identified and corrected, which supports process integrity but also signals MRV/control weaknesses that increase over-crediting risk.

Project Description

We at Bussme keep circular economy at the heart of our business, our district heating network as the bloodstream and our biochar as the muscles in carbon removal. We are designing, building and operating biomass based district heating plants in Southern Sweden. Our district heating systems enable buildings, companies and municipalities to convert from fossil oil and gas to carbon-neutral heating. The level of carbon in our biochar typically ranges between 85-90% indicating the quality of our pyrolysis units and the biochar itself. We strongly believe in biochar as a product with its physical features but also as carbon sink. And we think it is one of the most accessible ways of defying climate change. For this reason we have set a target to produce 10 000 m3 of biochar during 2022. This will be done by commissioning two new plants in 2021.

Red Flags

  • Verified and claimed removal totals were not found in the extracted record, limiting the ability to assess crediting accuracy.
  • A material discrepancy between reported production and shipped volumes caused a 7% impact on issued CORCs, indicating MRV/data control weaknesses.
  • Leakage deduction and justification were not found in the extracted record.

Cosa migliorerebbe questo punteggio

  • Disclose (or extract) the verified and claimed removal totals for the monitoring period, including calculation steps and uncertainty/QA checks tied to CORCs issuance.
  • Provide explicit leakage assessment (deduction percentage and justification) and baseline approach details from the Puro Biochar Methodology application for this project, plus evidence of grievance mechanism/FPIC where applicable.

Questi suggerimenti indicano quali prove pubbliche aggiuntive potrebbero migliorare il livello di confidenza di questa valutazione. Non garantiscono un punteggio futuro più alto.
