Isometric, a UK-based carbon removal registry, has released two new modules for certifying biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More carbon removal, one for mobile production and one for small-scale and distributed projects. These modules operate in conjunction with the core protocol—rather than modifying it—and are intended to expand its applicability across a broader range of project structures and kiln types. The approach specifically targets decentralized networks operating in rural settings where industrial-scale infrastructure is often absent, enabling more flexible certification pathways for diverse global contexts.

One of the central challenges addressed by these modules is the difficulty of maintaining rigorous monitoring, reporting, and verification (MRV) standards across decentralized production sites. Traditional carbon credit frameworks tend to favor large, centralized facilities due to simpler data collection and oversight. In contrast, distributed systems rely on numerous small-scale reactors managed by individual operators or community groups, creating fragmentation that can introduce risks around data integrity, consistency in pyrolysis conditionsThe conditions under which pyrolysis takes place, such as temperature, heating rate, and residence time, can significantly affect the properties of the biochar produced.   More, and accurate carbon accounting.

To address these challenges, Isometric’s modules incorporate a digital MRV (dMRV) framework built on automated data collection and secure cloud-based storage. The system introduces a tiered responsibility structure that separates operators from supervisors to reduce the risk of data manipulation. Reactors are required to use sensors that capture key parameters—such as temperature and residence time—at minute-level intervals, ensuring consistency across batches. In addition, the modules define strict standards for feedstockFeedstock refers to the raw organic material used to produce biochar. This can include a wide range of materials, such as wood chips, agricultural residues, and animal manure. More traceability and sampling, including a requirement for a minimum of 15 moisture measurements per batch to account for biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More variability.

Together, the protocol and its supporting modules enable high-quality distributed projects to participate in the formal carbon market without altering the integrity of the underlying standard. Early adopters, including Carboneers and Varaha, are already using these modules to certify carbon credits generated by smallholder farming communities in regions such as India. The result is a scalable, modular framework that delivers fully traceable, ICVCM-aligned carbon credits while creating economic co-benefits for local communities. By formalizing pathways for decentralized production, Isometric is enabling global networks to contribute meaningfully to durable carbon removal at scale.
