Brent Constantz, CEO of building materials company Blue Planet, says he has a good solution: sequestering waste carbon dioxide into manmade limestone. ... If the carbon produced by those processes could be cut, it could result in a significant improvement.

Does limestone remove carbon?

Carbon is removed into long term storage by burial of sedimentary strata, especially coal and black shales that store organic carbon from undecayed biomass and carbonate rocks like limestone (calcium carbonate).

How does limestone affect the carbon cycle?

Weathering of limestone deposits by rain tends to return carbon atoms to the short term reservoirs and to atmospheric carbon dioxide. ... By providing calcium ions, weathering promotes limestone formation and removal of carbon dioxide from the atmosphere.
