Carbon dioxide removal registry Isometric has entered China’s carbon credit market by signing certification agreements with its first three local project developers: Tongao Greenchar, Vastwing Energy, and DeCarbon Tech. While DeCarbon Tech operates in direct air capture and mineral storage, 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 developers Tongao Greenchar and Vastwing Energy represent a pivotal advance for biomass-based sequestration in the region. The agreements enable these suppliers to certify their carbon removal projects against scientific standards, securing verified access to international corporate buyers on global voluntary carbon markets.

China faces a major carbon management mandate as it targets carbon neutrality by 2060, an objective requiring an estimated three billion tonnes of annual carbon dioxide removal to offset residual emissions. The country holds the world’s largest technical potential for biochar carbon sequestration, with agricultural crop residues alone capable of removing an estimated 470 million tonnes of carbon dioxide annually. However, domestic project developers historically encounter substantial friction connecting with global capital. Without rigorous, accredited third-party verification protocols, suppliers struggle to demonstrate permanence, quantify lifecycle emissions, and satisfy the strict procurement criteria demanded by multinational credit purchasers.

To bridge this verification gap, Isometric is deploying its AI-powered Certify platform and modular Biochar Protocol across Chinese project sites. Tongao Greenchar and Vastwing Energy convert agricultural and forestry residues into durable biochar for soil applications, preventing the open burning or decomposition of biogenic waste. Isometric’s digital platform streamlines data submission and lifecycle analysis, allowing independent verifiers to audit operations rapidly and issue high-integrity credits with defined durability thresholds of 200 or 1,000 years.

This expansion integrates China’s vast 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 conversion capacity into institutional voluntary carbon markets. By securing third-party verification through Isometric, Tongao Greenchar and Vastwing Energy establish a transparent pipeline for high-durability credits sourced from Chinese feedstocks. The partnerships demonstrate that standardizing measurement, reporting, and verification mechanisms can unlock regional biochar supply at gigaton scale, providing international buyers with verifiable carbon removals while monetizing agricultural waste streams across China.
