Carbon Market Watch has released a report comparing four major carbon credit rating agencies: BeZero Carbon, Calyx Global, Renoster, and Sylvera. The report is significant because there is currently no standardized methodology for assessing carbon credit quality, and such standardization is crucial for transparency in the voluntary carbon market (VCM). Each agency has its own approach, with differences in qualitative assessment, algorithmic analysis, and testing methods. The report highlights variations in handling factors like additionality, double issuance, co-benefits, permanence benchmarks, and leakage, among others. This comparison aims to shed light on the diverse approaches used by these agencies in carbon credit assessment.
