A recent report by Carbon Market Watch compares four major carbon credit rating agencies – BeZero Carbon, Calyx Global, Renoster, and Sylvera. The comparison is significant because there is currently no standardized, universally accepted assessment methodology for carbon credit quality. With recent scandals surrounding faulty carbon credits and subpar offset schemes, there is a need for standardization and robust methodologies to bring more transparency to the voluntary carbon market.
Carbon credit rating agencies are working on developing such standards and methodologies to provide comprehensive ratings. However, these ratings may differ significantly from one another. The report by Carbon Market Watch provides a unique comparison of each agency’s approach and highlights their main differences.
One of these differences is Renoster’s approach, which relies more on an algorithmic analysis and limits its qualitative assessment. Renoster also uses mostly implicit tests, as opposed to the direct tests used by other agencies for their assessments.
The report also focuses on other important differences among the agencies. This includes how they deal with factors like additionality, double issuance, double counting, co-benefits, permanence benchmarks, leakage, and more.
The lack of standardized assessment methodologies in the carbon credit market has been a concern, as it can lead to inconsistencies and uncertainties. The comparison provided by Carbon Market Watch’s report helps shed light on these differences and underscores the need for standardization in the industry.
Overall, the report by Carbon Market Watch provides valuable insights into the approaches and methodologies of four major carbon credit rating agencies. It highlights the need for standardized assessments and emphasizes the importance of transparency in the voluntary carbon market.
