By applying powdered silicate rocks rich in calcium and magnesium, such as basalt, the dissolution process can be accelerated to sequester CO₂ in the form of dissolved inorganic carbon (DIC) within soil porewater, which is ultimately transported to the ocean, achieving long-term carbon storage. Using a life cycle assessment (LCA) framework, this study evaluates the feasibility of basalt-based enhanced rock weathering in China, focusing on its environmental and economic implications across various application scenarios.
