The first Rubicon Rated Tonne has received an AA_port rating under BeZero’s new portfolio-specific methodology.
This curated portfolio is designed for companies where procurement offices require third-party assessments of carbon credits.

Rubicon Carbon, a carbon credit management firm, today launched the Rubicon Rated Tonne (RRT), a new set of curated carbon credit portfolios for customers seeking credits with third-party verification. The first of these portfolios has received an AA_port rating by BeZero Carbon, a leading independent carbon ratings agency, through its new Portfolio Rating framework, indicating that each portfolio credit has a very high likelihood of achieving one tonne of CO₂e avoidance or removal.

Rubicon Carbon develops portfolios of carbon credits to minimize the risks associated with carbon credit purchases, build buyer confidence, and catalyze investment in climate resilience projects. A complement to Rubicon Carbon’s existing offering, the first RRT includes carbon removal, nature-based, and super-pollutant elimination projects. All of these projects have passed the company’s stringent due diligence process and, in addition, have received an AA_port rating based on the quality of their underlying credits.

“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. This partnership underscores Rubicon Carbon’s and BeZero’s shared commitment to transparency and environmental integrity. With risk-adjustment already built into the Rubicon Carbon Tonne, we’re excited to bring third-party validation and rigor to this innovative approach.

To qualify for a BeZero portfolio rating, all individual credits must be rated B or higher and have an additionality risk rating of ‘b’ or above. Additionally, at least 25% of the credits must match the portfolio's overall rating, none may be more than two notches below it, and lower-rated projects require additional credit retirements based on BeZero’s discount schedule to ensure carbon integrity.

By purchasing carbon credit portfolios that incorporate risk adjustment, buyers gain greater confidence in determining how many credits they need to effectively address their emissions, verified by BeZero’s independent portfolio rating. The portfolio rating is time-stamped and updated regularly to ensure it reflects the latest portfolio composition.

Tommy Ricketts, BeZero Carbon’s CEO and co-founder, said, “We are thrilled to be partnering with Rubicon Carbon’s team to bring a first-of-its-kind innovation for carbon markets, combining their portfolio of credits with BeZero’s Portfolio Rating methodology.”

Ricketts added, “The BeZero Carbon Rating is an independent, live, public assessment of the risks individual projects face in achieving a tonne of CO₂e. The portfolio uses our ratings and applies strict rules to give buyers greater confidence to make credible, risk-adjusted claims. 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.”

This launch is the latest in Rubicon Carbon’s continued efforts to bring institutional-quality carbon solutions to market, helping global organizations invest in credible, scalable, and science-based climate action. For more information on Rubicon Carbon, visit the website or follow on LinkedIn.
