Durable carbon removal isnโt just an engineering challenge; itโs about optimising Earthโs existing geochemical cycles at scale.
Enhanced Rock Weathering (ERW) is rapidly emerging as one of the most promising pathways for high-permanence carbon dioxide removal (CDR). By accelerating natural geological weathering, we can sequester atmospheric carbon for thousands of years while delivering tangible agricultural co-benefits.
Bengaluru-based climate-tech startup Alt Carbon recently passed a major operational milestone, removing over 9,566 tonnes of COโ by spreading finely crushed basalt across tea estates and agricultural land in India.
From a Sustainability Strategy & Carbon Accounting perspective, ERW offers a strategic double-win:
๐ชจ High-Permanence Sequestration: Crushed basalt reacts with rain and atmospheric COโ, converting dissolved carbon into stable bicarbonate ions that remain safely stored for millennia.
๐ฑ Soil & Yield Co-Benefits: Basalt weathering restores essential silicate and micronutrients, mitigates soil acidity, and boosts crop productivity, directly linking climate action to agricultural resilience.
๐ Dual-Use Infrastructure: Deploying across existing farmlands and tea plantations leverages existing operational land without requiring dedicated real estate or competing with food production.
The Strategic Takeaway for Corporate Net-Zero Roadmaps:
As enterprise buyers shift focus from short-term avoidance offsets to high-durability removal credits, nature-based geochemical solutions like ERW bridge the gap between high permanence and real-world ecological co-benefits.
To my network: How is your organization evaluating durable CDR pathwaysโlike ERW, biochar, or DACโto address residual Scope 3 emissions?
