Rubicon Carbon has introduced the Rubicon Rated Tonne (RRT), a new portfolio-based approach to carbon credit purchasing, offering buyers a curated selection of verified credits supported by third-party ratings. The first RRT portfolio has received an AAport rating from BeZero Carbon, an independent carbon ratings agency, through its new Portfolio Rating framework.
Designed to address quality and credibility concerns in the voluntary carbon market, the RRT portfolios combine carbon removal, nature-based, and super-pollutant elimination projects. All included projects have undergone Rubicon Carbon’s due diligence and meet the standards required for BeZero’s portfolio rating — which requires individual credits to be rated B or higher and have a low additionality risk. The framework also imposes diversification and quality constraints, with discounting applied to lower-rated credits to maintain integrity.
Tom Montag, CEO of Rubicon Carbon, stated the initiative aims to enhance buyer confidence and transparency in carbon markets. “We believe cooperation among industry leaders is key to growing the voluntary carbon market and helping companies meet their climate goals,” he said.
The new framework allows purchasers to account for risk-adjusted climate benefits more precisely, as each portfolio is independently reviewed and updated to reflect its latest composition. This ensures that credit buyers can make informed and credible claims about their carbon offset strategies.
BeZero Carbon CEO Tommy Ricketts described the collaboration as a milestone for market innovation. “The BeZero Portfolio Rating brings clarity to a complex market, helping buyers understand the risks and quality of their investments in carbon projects,” he said.
The RRT launch marks the latest step in Rubicon Carbon’s efforts to provide scalable and science-backed carbon credit solutions to institutional clients globally.
