Score Breakdown

Integrity

verified The verification report confirms additionality was verified by the VVB.

missing Leakage treatment and baseline approach were not found in the extracted record, weakening robustness of net removals.

Transparency

verified The verification report provides a defined monitoring period (2023-01-01 to 2024-01-31) and names the VVB (DNV Business Assurance Finland Oy Ab).

missing Total removals claimed and verified were not found in the extracted record, limiting independent scrutiny.

Claim Safety

verified A material error was identified and corrected (revised CORCs calculation), indicating issues were surfaced rather than ignored.

missing CORSIA eligibility and CCP status were not found in the extracted record, and key quantifications (claimed/verified removals) are missing, increasing greenwashing/over-crediting risk.

Documentation

verified A recent verification report is available (dated 2025-03-03) with a named VVB and references to multiple documents (7 used).

missing Evidence document list is not specific in the extracted record and extraction confidence is only medium.

Detailed Analysis

Integrity

The verification report (2025-03-03) indicates additionality was confirmed by the VVB, which supports additionality robustness. However, the baseline approach and any baseline reassessment timing were not found in the extracted record, making it hard to judge counterfactual validity. Leakage deduction and leakage justification were also not found in the extracted record, which is a notable gap for a biomass/biochar system. A buffer contribution of 2.5% is stated, but no reversal events were found in the extracted record, leaving permanence performance only partially evidenced.

Transparency

Transparency is moderate because the verification report (2025-03-03) clearly identifies the VVB (DNV Business Assurance Finland Oy Ab) and the monitoring period (2023-01-01—2024-01-31). At the same time, the extracted record does not include total removals claimed or verified, which limits the ability to reconcile issuance with monitoring outcomes. Key monitoring specifics such as usage monitoring method were not found in the extracted record.

Claim Safety

Claim safety is constrained by missing quantifications: total removals claimed and verified were not found in the extracted record, increasing the risk of overstated marketing claims. The verification report (2025-03-03) reports a material discrepancy between reported production and shipped volumes with a 7% impact on CORCs, and notes the calculation was revised, which reduces risk going forward but signals prior over-crediting exposure. CORSIA eligibility and CCP status were not found in the extracted record, so buyers cannot easily assess alignment with higher-integrity eligibility screens.

Documentation

Documentation quality is fair: the extracted record is anchored in a recent verification report (2025-03-03) and indicates 7 documents were used, with a named VVB. However, the evidence document list is not specific (listed as unknown), and several core fields (baseline, leakage, totals) were not found in the extracted record, indicating incomplete extractable disclosure. Minimum extraction confidence is medium, which modestly reduces confidence in completeness.

Overall

Overall, the project appears to have a functioning assurance process (VVB involvement and a documented correction of a material error), but key accounting elements and totals are missing from the extracted record, limiting confidence in net removal claims. No contradictions were identified in the extracted record, so no cross-document reconciliation was required. Note the gate rules: documentation is above 3.0 so transparency would not be capped, and integrity is above 4.0 so the overall score would not be capped post-scoring.

Audit Analysis

This Puro biochar removal project has some integrity strengths, including VVB-confirmed additionality and a stated buffer contribution, but key accounting elements (baseline and leakage treatment) were not found in the extracted record. A material discrepancy affecting 7% of issued CORCs was identified and corrected, which supports process integrity but also raises over-crediting risk if controls are weak.

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

  • Baseline approach and reassessment timing were not found in the extracted record, limiting confidence in counterfactual assumptions.
  • Leakage deduction and justification were not found in the extracted record for a biomass/biochar supply chain where leakage can be material.
  • Verification report identified a material discrepancy between production and shipped volumes with a 7% impact on CORCs.

Cosa migliorerebbe questo punteggio

  • Disclose the baseline approach and any reassessment schedule in publicly accessible documentation, with clear justification aligned to the Puro Biochar Methodology (Edition 2022 Version 3).
  • Publish leakage assessment results (deduction percentage and justification) and provide a clear reconciliation table showing total removals claimed vs verified for the monitoring period.

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