First-ever rated carbon credit portfolio: Rubicon Carbon’s new Rubicon Rated Tonne (RRT) is the first to receive BeZero Carbon’s AAport rating, indicating high confidence in climate impact.
Enhanced transparency for buyers: The third-party verified rating gives corporate procurement teams assurance in the effectiveness of purchased credits.
New market standard for carbon integrity: BeZero’s methodology sets rigorous thresholds, offering a risk-adjusted, portfolio-level lens for assessing carbon credit quality.
Rubicon Carbon has launched the Rubicon Rated Tonne (RRT), a portfolio of rigorously vetted carbon credits that has received an AAport rating from BeZero Carbon under its new Portfolio Rating framework—the first time a carbon credit portfolio has been independently rated at this level.
The RRT is designed to help corporate buyers—especially procurement teams—navigate carbon credit investments with greater confidence, thanks to third-party verification. The inaugural portfolio includes a diversified mix of carbon removal, nature-based, and super-pollutant elimination projects, all of which have undergone Rubicon’s internal due diligence and now meet BeZero’s stringent quality criteria.
“We believe that growing the voluntary carbon market will require cooperation among industry leaders to build buyer confidence among companies seeking to make progress towards their sustainability goals,” said Tom Montag, CEO of Rubicon Carbon.
BeZero’s rating framework assesses portfolios using strict criteria:
Each credit must be rated B or higher individually.
At least 25% of credits must match the portfolio’s overall rating.
Projects more than two notches below the average rating are excluded.
Lower-rated credits require additional retirements based on BeZero’s discounting methodology.
These measures ensure the climate impact integrity of the portfolio. Importantly, the ratings are updated regularly and time-stamped, offering buyers a transparent and dynamic view of portfolio quality.

“The BeZero Carbon Rating is an independent, live, public assessment of the risks individual projects face in achieving a tonne of CO2e,” said Tommy Ricketts, CEO and co-founder of BeZero Carbon.
“It is a piece of market innovation that acknowledges the reality that not all carbon credits are created equal, while also recognizing the importance of investing in high-quality carbon projects to drive meaningful climate action.”
Rubicon Carbon’s new offering marks a significant step in its strategy to scale institutional-quality carbon solutions, enabling global organizations to make credible, science-based climate investments.
