Isometric has signed its first three project developers in China, providing the high-quality certification their carbon removal projects need to access international buyers. Direct air capture (DAC) company DeCarbon Tech was the first to sign, followed by biochar developers Tongao Greenchar and Vastwing Energy.
China has committed to reaching net zero by 2060, which will require deep emissions reductions as well as an estimated 3 billion tonnes of carbon removal per year to offset residual emissions.
The country is well positioned to deliver removal at that scale. China’s rapid build-out of renewable power, paired with an established manufacturing base, is lowering both capture and deployment costs for DAC. China also has more potential to remove carbon dioxide through biochar than any other country. If all of its crop residues were used, the biochar produced could remove an estimated 470 million tonnes a year.
“China is one of the best-placed countries on earth to deliver carbon removal and reduction at scale, from direct air capture and biochar to superpollutant reduction in rice paddies. We’re looking forward to working with these developers, and many more, to ensure every certificate represents real, measurable climate impact,” said Lukas May, Chief Commercial Officer at Isometric.
Isometric will certify the carbon removed by the three project developers against its scientifically rigorous protocols using the AI-powered Certify platform, opening access to the global carbon market. Isometric is the world’s largest certifier of carbon removal, with more than 16 million tonnes contracted to date by buyers including Microsoft, JPMorganChase, and Boeing.
DeCarbon Tech, Isometric’s first Chinese project developer, is a direct air capture company that captures atmospheric carbon dioxide and stores it permanently through mineralization. It also supplies captured carbon dioxide for industrial use, and is building capacity to support net-zero industrial systems.
“We partnered with Isometric because of its rigorous, science-based approach and its strong recognition among global carbon credit buyers,” said Leo Liao, Co-founder of DeCarbon Tech. “Building on the experience from our demonstration facility, DeCarbon Tech is scaling reliable delivery while lowering the cost of high-quality carbon removal. Together with Isometric, we look forward to bringing China-developed DAC credits to the global market.”
Tongao Greenchar, established by Tongao Group and Greenchar Climate Solutions, is an integrated project developer that converts responsibly sourced agricultural and forestry residues into durable biochar, which is used in traceable soil applications and biochar-based fertilizer products. Its approach spans biomass sourcing through to long-term monitoring.
“Through our collaboration with Isometric, we want to demonstrate that China can deliver durable carbon removal at scale while transforming agricultural residues into lasting value for the climate, soils, farmers and rural communities. Tongao Greenchar is committed to playing an important role in making this vision a reality,” said Qian Guoqiang, Chairman of Tongao Greenchar.
Vastwing Energy is developing a biochar project in Longnan City, Gansu Province, converting discarded fruit tree branches into durable biochar through gasification technology, for application to agricultural soils. The project has the potential to produce 75,000 tonnes of biochar-based fertilizer per year.
“Vastwing is committed to developing industrial-scale projects that unlock China’s carbon removal potential. Our Longnan biochar project is the first step, and we are preparing two additional biochar projects for submission to Isometric later this year,” said Kan Li, General Manager at Vastwing Energy. “Isometric’s scientific expertise and proactive support give us confidence in scaling high-integrity carbon removal solutions from China to global markets.”
