Swiss company Climeworks has successfully taken carbon dioxide out of the atmosphere and put it underground, where it will eventually turn into rock. The process has been verified by an independent third-party auditor. Corporate clients have bought future carbon removal services from Climeworks and individuals can also pay to offset their personal emissions. The cost of carbon dioxide removal and storage for corporate clients is about several hundred dollars per ton. Climeworks' largest carbon dioxide removal facility is located in Iceland, where it partners with CarbFix, which stores the gas underground. In June 2022, Climeworks announced it had begun construction of its second commercial-sized plant in Iceland that will capture and store 36,000 metric tons per year of carbon dioxide.
