Heqing Solar Cooker Project
Score Breakdown
Integrity
verified Additionality was tested using an investment test and the VVB confirmed it in the verification report.
missing The monitoring report lists multiple material findings and required corrective actions, including missing ex-post versus ex-ante comparison and VVB rotation rule concerns.
Transparency
verified The monitoring period and crediting period are stated, and the VVB name is identified in the extracted record.
missing Total claimed and verified emission reductions are not found in the extracted record, and the monitoring approach relies on self-reporting without a verified usage rate.
Claim Safety
verified Leakage is described as negligible with a 0% deduction, which is better than an unquantified leakage treatment.
missing The baseline is project-specific rather than a clearly reassessed standardized baseline, and the record does not provide a verified usage rate to test over-crediting risk.
Documentation
verified The record draws on many documents, with 21 documents used and a medium extraction confidence rather than low.
missing The monitoring report contains numerous corrective actions and the extracted evidence list is sparse, with at least one document source shown as unknown.
Detailed Analysis
Integrity
The project has a positive integrity signal because the verification report confirms additionality through an investment test, and the monitoring report states leakage is deemed negligible with a 0% deduction. That said, the same monitoring report lists several material findings, including missing comparison of estimated versus achieved reductions, inconsistent references, and unresolved questions around site visits and VVB rotation rules, which weakens confidence in the robustness of the crediting claim.
Transparency
Transparency is limited by missing core quantitative fields in the extracted record: total claimed and verified emission reductions are not found, and the usage rate is only described as self-reported with no verified value. The monitoring period and crediting period are available, but the documentation still leaves important MRV details incomplete, and the medium extraction confidence suggests the record is not fully clean.
Claim Safety
Claim safety is moderate at best. The project is an avoidance activity with a project baseline and a stated negligible leakage treatment, but the absence of a verified usage rate and the lack of any quantified comparison between expected and achieved reductions increase over-crediting risk.
Documentation
Documentation quality is mixed: 21 documents were used and extraction confidence is medium, which is acceptable, but the monitoring report itself contains many required corrections and missing explanations. The evidence set also appears incomplete for some key items, with at least one source listed as unknown and several important values not found in the extracted record.
Overall
I privileged the more recent monitoring report for leakage and MRV issues, while noting that it conflicts with an earlier document on leakage treatment and usage monitoring method; the later record says leakage is negligible and monitoring is self-reported, whereas the earlier record indicated leakage was not addressed and usage was annual survey. Because the later document is more recent and appears to be the latest monitoring evidence, I gave it more weight, but the contradiction itself lowers reliability. The project is not obviously weak on additionality, yet the verification findings and missing quantitative MRV outputs keep the overall score in the middle range.
Audit Analysis
This is a registered VCS cookstove avoidance project with VVB-confirmed additionality and a stated negligible leakage treatment, which supports moderate integrity. However, the monitoring package shows multiple verification findings and missing evidence on key MRV items, so confidence in the claimed reductions is only moderate-to-low.
Project Description
The Heqing Solar Cooker Project is located on the rural area of Zhangye, Gansu province in northwestern China. The project has installed 49,000 solar cookers for the rural residents. Coal is overwhelmingly the main energy source for rural residents in this region of China. The proposed project will enable the rural residents to efficiently substitute solar energy for the fossil fuel (coal) used in daily cooking and water boiling, avoiding CO2 emission that would be generated by fossil fuel consumption. It is estimated that 143,762 tCO2e emission reductions will be produced annually. The rural area in Zhangye is an underdeveloped region and an ideal region for utilizing solar energy. Located at high altitude, this region has many sunny days. It is one of the most suitable regions in China for utilizing solar energy. The proposed project will significantly contribute to sustainable development of this region. It will serve as a model for future project. It will promote the use of clean energy, educate and train the rural population on solar energy technology, and build awareness in environmental protection among the rural population. 49,000 low-income households / about 196,000 villagers (average household has 4-5 people) directly benefit from the project. The rural residents will get clean and reliable energy supply for their daily cooking.
Red Flags
- The verification report identified several material issues, including a missing comparison between estimated and achieved emission reductions, inconsistent references, and a failure to verify ongoing stakeholder communication.
- The extracted record contains contradictions on leakage treatment and usage monitoring method, and the project relies on self-reported usage with no verified usage rate found.

Cosa migliorerebbe questo punteggio
- Publish a complete ex-ante versus ex-post emissions comparison with the underlying calculation spreadsheet and verified emission reduction totals.
- Resolve the monitoring inconsistencies by documenting the final leakage rationale, the actual usage monitoring method, and a verified usage rate from independent field evidence.
Questi suggerimenti indicano quali prove pubbliche aggiuntive potrebbero migliorare il livello di confidenza di questa valutazione. Non garantiscono un punteggio futuro più alto.
