Carbon removal registry Isometric has introduced a new protocol designed to optimize 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 production and storage for long-term carbon sequestration. Released for public feedback on July 3rd, the protocol was developed by Isometric’s science team alongside experts from the Isometric Science Network, which includes over 200 carbon removal specialists. This protocol integrates recent research by Hamed Sanei and collaborators.

Biochar, a carbon-rich material produced by heating 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 in low-oxygen conditions (pyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More), can be effectively stored and used in various ways. Isometric’s protocol focuses specifically on biochar made from pyrolyzed waste biomass and its application as a soil amendmentA soil amendment is any material added to the soil to enhance its physical or chemical properties, improving its suitability for plant growth. Biochar is considered a soil amendment as it can improve soil structure, water retention, nutrient availability, and microbial activity.   More in agricultural surface soils. Using biochar in agriculture can enhance soil health, improve nutrient retention, and boost water management, thereby promoting better plant growth.

The protocol aims to assure buyers of biochar credits about the security of their investment through a three-step process. It accounts for the predictable rate at which a portion of the carbon in biochar is released into the atmosphere, influenced by factors like biochar composition and site conditions. Only the durable carbon fraction in the biochar is eligible for credit generation, with a lower threshold for the carbon-to-hydrogen ratio and consideration of application losses.

The protocol also includes guidelines for assessing biochar durability, sustainable biomass sourcing criteria, and environmental protection measures. It is now open for public consultation, with feedback to be incorporated before finalization.
