The cost of carbon dioxide removal and storage for these corporate clients is confidential and depends on what quantity of carbon dioxide the companies want to have removed and over what period of time. But the general price for carbon removal runs to several hundred dollars per ton. Individuals can also pay to Climeworks to remove carbon dioxide to offset their personal emissions.
