Spreading finely ground basalt rock on farmlands extensively is a method known as enhanced weathering, which involves the capture and storage of carbon dioxide through the natural process of rock weathering.

Increasing alkalinity by adding lime can help facilitate carbon capture in certain environments, such as ocean fertilization projects aimed at enhancing the ocean's capacity to absorb and store carbon dioxide.

Capturing carbon dioxide released by industries and injecting it into abandoned subterranean mines as carbonated waters is a technique known as carbon capture and storage (CCS), which involves capturing CO2 emissions from industrial sources and storing them underground to prevent their release into the atmosphere.
