A system for removing CO2 from air such as atmospheric air is described that uses a cooling tower, a pseudo-cooling tower, or a wind capture device to provide a large volume of atmospheric air. A CO2 capture apparatus is positioned to contact atmospheric air moving towards or within the cooling tower, pseudo-tower, or wind capture device, and includes wherein the CO2 capture apparatus includes a CO2 binding agent that binds to CO2 in atmospheric air. An associated reprocessing apparatus releases C02 from the binding agent, directs the released CO2 to a CO2 storage chamber, and returns the binding agent to the CO2 capture apparatus. A system for removing CO2 from flue gas is also described.
