🔬 Top Story: Cornell Study Puts ERW at Up to 1.1 Billion Tonnes/Year by 2100 A new study in Nature Communications Sustainability by Cornell’s Chuan Liao and colleagues models realistic adoption scenarios for enhanced rock weathering (ERW) — the practice of spreading crushed silicate rocks (like basalt) on agricultural fields to accelerate natural CO₂ drawdown. The findings: 350M–750M tCO₂/yr by 2050 and 700M–1.1B tCO₂/yr by 2100. That’s far below earlier theoretical ceilings of 5 Gt/yr but still a massive contribution to climate mitigation. A key takeaway: the Global South would eventually surpass the Global North in ERW deployment as supply chains mature, making the technique a potential equity lever for global carbon markets.

While most CDR headlines focus on North America and Europe, Asia is quietly building serious carbon removal capacity. The latest example: Japan’s Green Carbon Inc. has partnered with Ahmedabad-based Excellent Enfab to deploy industrial-scale biochar production in India. The Deal Two new pyrolysis plants will be built in Gujarat and West Bengal. Feedstock comes from locally sourced agricultural residues — peanut shells, flower stems, bamboo — the kind of waste that would otherwise decompose and release CO₂ back into the atmosphere. ...

The geography of carbon removal is shifting. Japan’s Green Carbon Inc. has partnered with India’s Excellent Enfab Incorporation to build an industrial-scale biochar carbon removal plant in Ahmedabad, Gujarat. Commercial operations are planned for Q2 2026. The Partnership Green Carbon, headquartered in Japan, has built a diverse CDR portfolio spanning rice paddy credits, biochar, forest conservation, carbon farming, mangrove planting, and cattle methane reduction across Japan, Southeast Asia, Australia, and South America. ...
