Score Breakdown

Integrity

verified Additionality was confirmed by TÜV Rheinland (China) Ltd using an investment test, and the verification process reported no unresolved material findings.

missing Leakage treatment is weak: the record says leakage was not addressed, even though a 0% deduction was applied, and reversal risk is not discussed.

Transparency

verified The monitoring period is clearly stated as 2012-09-01 to 2013-08-31, and the project has an identified VVB.

missing Key reporting figures are missing, including verified and claimed emission reductions, and the extracted record shows conflicting descriptions of how usage was monitored.

Claim Safety

verified The project uses a project baseline under AMS-I.C., and additionality was independently verified.

missing Claim safety is weakened by the absence of verified emission totals, no stated FNRB value, and no clear CORSIA or CCP status.

Documentation

verified The record includes multiple official-document elements such as the VVB name, monitoring period, safeguards, and a list of resolved findings.

missing Extraction confidence is only medium, the evidence-doc list is effectively incomplete, and there are contradictions on both usage monitoring and the crediting period.

Detailed Analysis

Integrity

The verification report evidence is moderately strong because additionality was confirmed by TÜV Rheinland (China) Ltd using an investment test, and the verification process noted one corrective action request and one clarification request that were satisfactorily resolved. However, the baseline is project-specific rather than a more robust standardized baseline, leakage is marked as not addressed despite a 0% deduction, and reversal risk is not discussed in the extracted record. The absence of a buffer pool figure also limits confidence in permanence controls.

Transparency

The monitoring period is clearly stated, and the project has an identified verifier, which helps traceability. That said, the extracted record does not provide claimed or verified emission reduction totals, the FNRB is not applicable, and the usage monitoring method is inconsistent across documents. The lack of a buffer pool figure and missing registry completeness details further reduce transparency.

Claim Safety

Claim safety is only moderate because the project has a verified additionality test and a defined methodology, but the baseline remains project-specific and leakage is not substantively justified. There is no verified usage rate, no FNRB value to compare against national defaults, and no clear CORSIA or CCP status in the record. These gaps make over-crediting risk harder to rule out.

Documentation

Documentation quality is limited by medium extraction confidence and an evidence set that appears incomplete in the extracted record. The project does include several useful elements, such as the VVB name, monitoring period, safeguards, and resolved findings, but key fields remain missing or unstated. The contradictions on usage monitoring and the crediting period indicate that the source documents are not fully aligned.

Overall

Overall, this is a mid-quality record with some credible integrity evidence but notable documentation and transparency gaps. I privileged the later-dated crediting-period statement from the 2013-11-28 document over the earlier 2012-12-08 version, and I treated the 2013-12-27 self-report usage method as the more recent statement while noting the contradiction with the annual survey description. These contradictions reduce reliability and keep the score below a strong-credit threshold.

Audit Analysis

The project has some positive integrity signals, including VVB-confirmed additionality and no unresolved material findings, but key risk controls are weak or missing in the extracted record. Transparency is limited by missing verification totals, no stated buffer pool, and contradictory documentation on usage monitoring and the crediting period.

Project Description

Developer: Clean Air Trade, Inc. Type: Solar Thermal - Heat Size: Small Scale Methodology: AMS-I.C. Thermal energy production with or without electricity Crediting period: 2010-09-15 → 2020-09-14 Estimated annual credits: 33482 tCO2e SDGs: Goal 15: Life On Land, Goal 3: Good Health and Well-Being, Goal 13: Climate Action

Red Flags

  • Leakage is not addressed in the extracted record, even though a 0% deduction is reported.
  • The documents conflict on the usage monitoring method and the crediting period, which reduces reliability.

Cosa migliorerebbe questo punteggio

  • Publish the verified and claimed emission reduction totals, along with the underlying calculation sheets and registry entries.
  • Clarify the usage monitoring method and provide a documented leakage and permanence assessment, including any buffer pool treatment.

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