Enhanced Rock Weathering (ERW) is a carbon sequestration technique that accelerates the natural process of rock weathering to capture atmospheric carbon dioxide (CO₂). In ERW, finely ground silicate rocks, such as basalt, are applied to agricultural soils. These rocks react with CO₂ in rainwater, forming stable carbonates that are eventually stored in soil or leached into oceans, removing CO₂ from the atmosphere.

The process not only helps reduce greenhouse gases but also improves soil health by releasing essential nutrients like calcium, magnesium, and potassium, promoting plant growth. ERW is a promising solution for mitigating climate change, as it can be integrated into existing agricultural practices and generate carbon credits through verifiable CO₂ removal.
