Score Breakdown

Integrity

verified The monitoring report states a quantified leakage treatment with a leakage deduction of 0% and no material findings reported.

missing Additionality testing is not stated and VVB confirmation is not found in the available documents.

Transparency

verified The monitoring period is clearly stated, and the file includes multiple source documents including the PDD, stakeholder consultation, and monitoring report.

missing Total claimed and verified emission reductions are not stated, and the VVB name is not found in the extracted record.

Claim Safety

verified The monitoring report uses a recent project-specific baseline and reports a quantified leakage approach.

missing The PDD and monitoring report disagree on usage rate assumptions, with 80% in the PDD versus 100% in the monitoring report, which increases over-crediting risk.

Documentation

verified The extraction confidence is high, and the monitoring report is dated 2019 with a defined crediting period and monitoring period.

missing Key documentation fields are missing, including the VVB name, additionality verification, and buffer pool information.

Detailed Analysis

Integrity

The monitoring report dated 2019-02-06 shows no material findings and no corrective actions required, which supports a cleaner verification outcome. Leakage is treated quantitatively with a leakage deduction of 0%, but permanence is not fully evidenced because buffer pool information is not found and reversal events are marked as not addressed. Additionality is weakly documented because no test type or VVB confirmation is stated in the available record.

Transparency

The monitoring period is clearly defined, and the evidence set includes the PDD, stakeholder consultation, and monitoring report, which helps traceability. However, the extracted record does not state total claimed or verified emission reductions, and the VVB name is missing. The registry is identified as Gold Standard, but the public-facing completeness of the file remains limited by these gaps.

Claim Safety

Claim safety is mixed because the project has a quantified leakage treatment and a recent project baseline, but the baseline is project-specific rather than a clearly standardized jurisdictional baseline. The contradiction on usage rate assumptions is important: the monitoring report uses 100% while the PDD used 80%, and I privilege the later monitoring report because it is more recent and directly tied to the monitored period. Even so, that discrepancy raises over-crediting risk and reduces confidence in the claimed savings.

Documentation

Documentation quality is moderate: the extraction confidence is high, the monitoring report is dated, and the crediting period and monitoring period are both available. Safeguards are better documented than many files, with FPIC conducted, a grievance mechanism present, and benefit sharing described. Still, the record lacks the VVB name, additionality verification, and buffer pool details, which prevents a stronger documentation score.

Overall

The project shows some credible process elements, especially safeguards and a quantified leakage treatment, but it is held back by missing core quality evidence. The contradiction on usage rate assumptions is material: I privilege the 2019 monitoring report over the 2015 PDD because it is later and more directly reflects the monitored period, yet the inconsistency still signals reliability risk. Because additionality is not demonstrated in the extracted record and permanence is only partially evidenced, the overall score remains mid-range rather than strong.

Audit Analysis

The project has some positive safeguards and a quantified leakage treatment, but the evidence base is incomplete on core quality items like additionality verification and VVB identity. A major inconsistency exists on usage rate assumptions: the monitoring report uses 100% while the PDD used 80%, and I privilege the more recent monitoring report because it is later and project-specific, but the contradiction still lowers confidence. Overall, this looks like a moderate-quality file with meaningful evidence gaps rather than a clearly high-integrity crediting case.

Project Description

Developer: CO2balance UK ltd Type: Energy Efficiency - Domestic Size: Microscale Methodology: GS TPDDTEC v 1. Crediting period: 2014-11-05 → 2021-11-04 Estimated annual credits: 10000 tCO2e SDGs: Goal 6: Clean Water and Sanitation, Goal 5: Gender Equality, Goal 3: Good Health and Well-Being, Goal 13: Climate Action

Red Flags

  • No additionality test or VVB confirmation is stated in the extracted record.
  • The PDD and monitoring report conflict on usage rate assumptions, which raises over-crediting risk.

Cosa migliorerebbe questo punteggio

  • Provide the VVB name and explicit verification language for additionality, baseline validity, and emission reductions.
  • Resolve the usage-rate contradiction with a documented rationale and publish the claimed versus verified emission totals.

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