Here are some key takeaways

In 2025, credits with a BeZero ‘A’ rating or higher reached their highest share of retirements yet, signalling a growing market preference for premium quality, even amid limited supply.
Retirement data between 2020 and 2025 (to date) show a statistically significant increase in credit retirement rates once a BeZero Carbon Rating has been assigned. Retirement rates almost double once a project is rated, and more than triple when a project is assigned a ‘A’ rating, reinforcing ratings as a clear signal to unlock buyer demand.
Buyers are chasing quality: retirements of projects rated ‘A’ or higher are rising fast despite tight supply, showing clear demand for high-quality credits.
