Researcher captures CO2 with mineral: "The theoretical potential is enormous"

The mineral olivine is able to capture large quantities of atmospheric CO2 and could help emitters reduce their climate footprint, says geologist Kristoffer Szilas, who's now starting a big research project to explore the matter.
