Rootella Carbon Value Proposition

Rootella Carbon Credits: Durable Nature-Based Carbon Dioxide Removal

Build Your Net-Zero Portfolio with Durable Carbon Dioxide Removal Credits

Rootella Carbon™ is an end-to-end soil carbon solution for durable Carbon Dioxide Removal (CDR) that leverages mycorrhiza, the Queen of Biologicals, to deliver scalability, integrity, and permanence.

Groundwork BioAg® is the project proponent and developer. Responsibilities include overall development and oversight of the Verra VM0042 v2.0 project including soil sampling and analysis, carbon credit sales, and distribution of up to 70% of carbon credit net proceeds to growers.

Rootella Carbon growers only need to enroll in the program and apply Rootella mycorrhizal inoculants seasonally to become eligible for carbon credits. Growers benefit from a new revenue stream that is independent of commodity prices, on top of agronomic benefits of mycorrhiza, including crop yield increases, fertilizer savings, and resistance to stress.

From Rootella to Carbon: Permanence and Integrity

High CDR Effect Size: 1-4 tCO₂e/ac annual sequestration. The average effect size of the 2023 cohort was 3.85 tCO₂e/ac, as measured across 8,989 treated and creditable acres in the US mid-west and mid-south.

Immediate Scalability: Rootella Carbon is administered through the Rootella Carbon Software Platform which enables rapid scale-up. The program grew by 10x in 2024 in North America and will expand to Brazil in 2025. Within this territory there are over 270M acres of low-till/no-till farms that are otherwise ineligible for carbon credits and represent an immediate market. Rootella mycorrhizal inoculants are currently sold across 3.7M acres annually in 23 markets, including US, Brazil, India and China.

Permanence: Mycorrhizae catalyze (5-10X) the formation of Mineral-Associated Organic Matter, with an estimated average half-life of 4,830 years. Project-level durability is inherent in the Verra CDR buffer pool.

Integrity: Rootella Carbon complies with the Verra VM0042 v2.0 methodology (Measure and Remeasure approach with Rootella-treated and control plots). Validation and verification from SCS Global Services, a third-party Verra-certified VVB

End-to-End Integrated Solution: The Rootella Carbon program starts with sales of carbon-sequestering biological products (Rootella mycorrhizal inoculants) to growers, culminating in sales of carbon credits to buyers.

Rootella Carbon Supports Farmers

Grower-centric: Satisfied growers are our core value and retaining them in the program is our long-term goal. Our generous revenue-sharing model, offering growers up to 70% of carbon credit net proceeds – in addition to Rootella’s proven agronomic benefits – reflects this commitment.
