Unveiling Enhanced Rock Weathering: Pathway to Net Zero Emissions

Enhanced rock weathering accelerates the natural process of CO₂ removal by spreading crushed rocks on agricultural fields. While modeling shows significant potential, precise measurement of CO₂ capture remains challenging across different soils. Understanding soil reactions and direct measurement are vital for realizing its climate change mitigation potential.

Queensland, Oct 30 (The Conversation) - Enhanced rock weathering presents a promising approach to accelerating CO₂ removal from the atmosphere. By crushing specific types of rocks and dispersing them over farmlands, the technique mimics natural processes to trap carbon more efficiently.

Studies suggest that if adopted globally, billions of tonnes of CO₂ could potentially be removed annually, offering a pathway to achieve net zero emissions. However, precise measurement of CO₂ capture is imperative, with results varying based on soil type, climate, and methodology.

The sector is rapidly evolving, yet without robust methods to gauge CO₂ absorption rates, policies and regulations may fall short. Further research and accurate measurement techniques are essential to assess its true climate mitigation potential.
