Sylvera analysis shows additionality as key differentiator for high-quality carbon projects
Sylvera's Q3 2026 analysis of carbon credit ratings reveals that additionality is the most significant factor distinguishing high-quality projects (rated BBB and above) from lower-quality ones (BB and below). For instance, ARR projects rated BBB and above averaged 4.2 for additionality, compared to 1.9 for those rated BB and below. While a strong Carbon Score is necessary, it does not consistently correlate with higher ratings, and permanence is most critical in projects with high reversal risk, such as biochar. This differentiation in quality is reflected in pricing, with BBB and above ARR credits averaging $23.47, nearly double the $12.80 for BB and below credits.
