Capricorn Ridge 4 Wind Farm
Score Breakdown
Integrity
verified The verification report confirms additionality was checked by the VVB using a combined test, and the project uses ACM0002 with a project baseline.
missing The issuance record lists multiple corrective actions and material findings, including calculation errors and outdated ERCOT data, which weakens confidence in the quantified reductions.
Transparency
verified The monitoring period, VVB name, verified emission reductions, and smart-meter monitoring approach are stated in the issuance record.
missing Total claimed reductions are not stated, and low extraction confidence suggests at least one key document was difficult to read.
Claim Safety
verified The project is an avoidance wind project with a quantified leakage deduction of 0%, and the baseline method is stated.
missing The record does not state CORSIA eligibility or CCP status, and the contradiction on leakage treatment shows some inconsistency in the source set.
Documentation
verified A large number of documents were used, and the VVB is identified as First Environment, Inc.
missing Low extraction confidence, several corrective actions, and contradictory dates for the crediting period and grievance mechanism reduce documentation quality.
Detailed Analysis
Integrity
The issuance record shows additionality was verified by the VVB, and the project uses ACM0002 with a project baseline, which is supportive for a wind avoidance project. The leakage deduction is stated as 0%, but the record also contains multiple corrective actions and material findings, including calculation errors and outdated ERCOT data, so the emissions accounting is not fully clean. Reversal risk is not a major issue for wind, but the record says reversal events are not addressed, which is a minor weakness.
Transparency
The monitoring period, VVB name, and verified emission reductions are clearly stated, and the monitoring approach uses smart meters. However, total claimed reductions are not found in the extracted record, and the extraction confidence is low, which suggests at least one key source was hard to read. The presence of several corrective actions also indicates the reporting trail was not fully straightforward.
Claim Safety
Claim safety is moderate because this is an avoidance project with a quantified leakage deduction of 0% and a stated baseline method. Still, the record does not state CORSIA eligibility or CCP status, so dual-market claim risk cannot be ruled out from the extracted facts alone. The contradiction on leakage treatment, where one document appears to have treated leakage as not addressed while the later issuance record says it was quantified, lowers confidence in the claim boundary.
Documentation
Documentation quality is weakened by low extraction confidence and by the number of corrective actions listed in the issuance record. The VVB is named and many documents were used, but the record also contains contradictions on leakage treatment, reversal events, grievance mechanism, and the crediting period. I privileged the later issuance record dated 2023-01-11 for the main values because it is more recent and appears to be the authoritative issuance-stage source, but the contradictions still reduce reliability.
Overall
The project looks materially better than a weak carbon credit, but it is not high confidence because the documentation is messy and the issuance record contains several corrective actions. I privileged the later issuance record from 2023-01-11 over older conflicting entries because it is more recent and likely reflects the final verified state, but I still discounted the score because the contradictions show the source set is not fully consistent. Under the gate rules, documentation is not low enough to cap transparency, and integrity is not below the threshold that would cap overall, but both remain constrained by the reliability issues.
Audit Analysis
This is a wind avoidance project with VVB-confirmed additionality and a quantified leakage treatment, which supports moderate integrity. However, the record has low extraction confidence, several corrective actions, and contradictions on leakage treatment, reversal history, grievance mechanism, and crediting period that reduce confidence in the documentation and claims.
Project Description
The Capricorn Ridge 4 Wind Farm Project in Sterling City, Texas, is a wind energy project that generates renewable electricity, thereby displacing electricity generated from fossil fuels. The project consists of 75 wind turbines and has a total capacity of 121.5 MW. The project is owned and operated by NextEra Energy Resources. The environmental benefits of the project include a reduction in greenhouse gas emissions. Specifically, the project is estimated to reduce CO2e emissions by 349,305 tonnes for the period of January 1, 2020, through December 31, 2021. The project is expected to reduce emissions by 1,865,780 tonnes of CO2e over the 10-year crediting period. In addition to the environmental benefits, the project also provides social and community benefits. The project creates jobs and generates revenue for the local community. The project also contributes to the state's Permanent School Fund through land usage fees.
Red Flags
- Low extraction confidence and many corrective actions indicate the record was not cleanly documented.
- Contradictions exist on leakage treatment, reversal events, grievance mechanism, and crediting period, which weakens reliability.

Cosa migliorerebbe questo punteggio
- Provide a clean, reconciled document set that resolves the contradictions on leakage treatment, reversal history, grievance mechanism, and crediting period.
- Publish the full monitoring and verification evidence for claimed versus verified reductions, including the missing claimed total and any supporting meter and ERCOT data.
Questi suggerimenti indicano quali prove pubbliche aggiuntive potrebbero migliorare il livello di confidenza di questa valutazione. Non garantiscono un punteggio futuro più alto.
