In the rapidly evolving landscape of environmental finance, a significant shift toward quality over quantity is reshaping the voluntary carbon market (VCM). Recent data from independent ratings agency BeZero Carbon suggests that the market is entering a phase of structural maturation, characterised by a ‘flight to quality’ as corporate buyers move away from legacy projects in favor of high-integrity assets.
The latest analysis, which tracks registry data from 2022 through early 2025, reveals a dramatic transformation in buyer preferences. Retirements of the highest-rated credits—those earning an 'A' to 'AAA' on BeZero’s eight-point scale—have more than doubled. These premium credits accounted for 22% of all retirements in 2025, up from just 10% in 2022.
Conversely, the market is actively de-prioritizing lower-rated options. Credits with 'C' or 'D' ratings saw their share of retirements plummet from 31% to 17% over the same period. This trend underscores a growing consensus among sustainability officers and investors: as public and regulatory scrutiny of climate claims intensifies, the reputational risk of ‘cheap"offsets far outweighs their initial cost savings.
The shift is most visible in the exodus from historic energy-sector credits, often criticized for low additionality. However, the market remains resilient; when these legacy credits are excluded, total retirements in 2025 reached nearly 150 million, indicating robust demand for verified, high-standard projects.

Supply-side dynamics are also correcting. Total credit issuances have fallen by approximately 50% from their 2022 peak. This contraction is helping to rebalance a market previously plagued by oversupply, aligning available inventory more closely with the specific needs of high-integrity buyers.
For project developers and investors, the most compelling takeaway is the widening quality premium. The data shows a clear financial incentive for high-rated projects:
- Nature-Based Solutions: In the restoration and afforestation sector, each incremental rating notch correlates to an average price premium of 87%.
- Renewable Energy: 'BBB'-rated credits now trade at roughly twice the price of 'B'-rated equivalents.
- Social Impact: 'A'-rated cookstove projects fetch double the price of those rated 'D'.
Reflecting on these shifts, Sebastien Cross, Co-founder and Chief Innovation Officer at BeZero Carbon, noted: ‘Carbon markets today are incomparable with where we were three years ago. Our analysis finds that businesses are increasingly showing a preference for higher-rated, lower-risk projects.’

As the market increasingly pivots toward high-integrity assets, the value of early-stage transparency cannot be overstated. At Green Earth, our commitment to these maturing market standards is woven into the design of every project we develop. By prioritising rigorous verification and long-term permanence, we ensure our initiatives—such as the Bulindi Agroforestry and Chimpanzee Habitat Restoration, Mount Kenya Regenerative Agroforestry, and Greenzone Reforestation projects—are built to exceed the tightening expectations of global investors. This dedication to excellence is already yielding results; our pipeline has secured strong Sylvera Estimated Ratings even at the pre-issuance stage, with Bulindi achieving a BBB class and our other projects firmly in the A–BB range. For project developers and sustainability officers, these ratings provide the necessary assurance that high-impact environmental work and financial value are being delivered side-by-side.
