Charm Industrial is a leading carbon removal technology company that permanently removes CO₂ from the atmosphere by converting agricultural and forestry residues into durable carbon storage products. Founded in 2018, Charm has established itself as one of the fastest-growing and most credible carbon removal companies, with major offtake agreements from Stripe, Google, Microsoft, Shopify, TD Bank, and other Fortune 500 companies.
Charm’s business model is built around the issuance of high-integrity carbon removal credits, making the accuracy, completeness, and traceability of production data critical for their bottom line. For years, Charm built out their own proprietary software, Ledger, to manage the measurement, reporting, and verification (MRV) of their processes. However, as operations scaled, they needed a more robust solution to house their digital infrastructure.
During the summer of 2025, Charm began evaluating solutions to their data scaling limitations. After conducting proof of concepts with leading digital MRV platforms, Charm selected Mangrove Systems due to the platform’s ability to:
Mangrove successfully integrated with Charm's operations and registry reporting in Q4 2025 to create a frictionless process from production to credit issuance. The platform handles data acquisition and review, dual-stream quantification, automated evidence generation, and everything in between. While Ledger remains available for public data viewing, Mangrove's digital data infrastructure now powers the backend operations.
Unlike single-output pathways, Charm must account for two distinct products: bio-oil and biochar. Each stream has its own accounting rules, permanence assumptions, and quantification methods, but because both products originate from the same feedstock, pyrolysis process, and upstream processing, the same operational data feeds both accounting streams.
Mangrove’s configurable production and quantification modeling allows Charm to account for both bio-oil and biochar within a single platform, without duplicating data submissions. Using a mass balance accounting approach, Mangrove tracks material flows and greenhouse gas emissions throughout the system, then allocates emissions profiles proportionally based on the carbon mass of each product output. This ensures accurate, protocol-aligned accounting for both streams while significantly reducing operational complexity and data reporting.
Beyond Charm's direct monitoring data, verification requires additional supporting evidence. For example, transportation emissions require clear documentation of routes and distances traveled.
Mangrove streamlines this process by automatically generating transport evidence from delivery logs. When Charm inputs start and end locations, Mangrove calculates the route and distance traveled and produces a corresponding map visualization using a Mapbox integration. This map screenshot serves as a clear, verifiable proof point for third-party verification bodies and reduces repetitive manual work to substantially diminish the burden on Charm’s reporting team.
As part of the rigorous requirements set by their registry partner, Isometric, specific accounting features are necessary to derive a conservative net quantification of carbon removal, such as uncertainty for data points with material impacts on the credit outcome and the amortization of embodied emissions.
Charm can define uncertainty for relevant data parameters directly within the platform, ensuring consistent application across data parameters and reporting periods. Additionally, Mangrove enables the setup of project establishment emissions, which significantly reduces the need for manual oversight and the risk of errors during verification.
Charm submits monitoring data to Isometric’s Certify portal through Mangrove’s dMRV API integration, the first connection of its kind to transmit data points and evidence files directly into the portal for verification body review. Data, documentation, and calculations flow seamlessly via API, streamlining reporting, verification, and credit issuance across platforms.
Internally, Charm relies on several on-site systems to ensure accurate operational and financial management, including Manufacturo as its Manufacturing Execution System (MES) and NetSuite as its Enterprise Resource Planning (ERP) system. This year, Mangrove will be integrating directly with these tools via API, automatically pulling required reporting data and eliminating time-consuming manual uploads.
Throughout the data collection process, Mangrove’s platform performs automated quality assurance checks, flagging anomalous values and identifying missing evidence before submission. These checks surface potential issues early before they are identified by verification bodies, supporting Charm’s internal QA/QC processes and reducing verification friction.
Looking ahead, Mangrove’s upcoming AI features will add an additional layer of confidence by using AI-driven verification reviews to identify high-risk corrective action areas prior to formal verification, further increasing the likelihood of smooth and timely credit issuance.
By implementing Mangrove as its digital MRV system, Charm has improved both the speed and reliability of its credit issuance process while reducing ongoing operational burden.
Charm reduced the time from the final monitoring date to credit issuance by 75 days relative to the industry average, accelerating cash conversion, lowering working capital financing costs and improving alignment with buyer delivery timelines. This reduction was driven by automated data ingestion, dual-stream quantification, pre-verification QA checks, and direct registry integration, eliminating common sources of delay between monitoring, verification, and issuance.
Operationally, Mangrove reduced reporting labor by 8 hours per reporting period for each pathway (bio-oil and biochar). With a monthly reporting cadence for bio-oil and anticipated quarterly cadence for char, this equates to 128 labor hours saved annually, freeing Charm’s technical and monitoring teams to focus on process optimization and project scaling rather than manual data preparation. With Mangrove, Charm has the ability to scale their CDR origination volumes without scaling MRV-related headcount.
Together, these improvements position Charm to issue credits more quickly, with greater certainty, and at lower marginal cost - strengthening its ability to meet buyer commitments while maintaining the high integrity required of durable carbon removal.
