Climeworks has just opened the world’s largest direct carbon capture plant. It can suck around 36,000 tons of CO2 from the air each year, burying it underground.
CO2 generally is released in cycles. Wood rots, new forests grow etc. The biggest issue is that we went from slow cycles such as carbon is stored in fossil fuels that VERY slowly release CO2 through natural processes, to extremely rapid release of CO2.
I don’t know what more efficient means here. The CO2 is stored sorta permanently underground, whereas trees release their CO2 when they rot or burn.
Trees are kind of better because they grow on their own, and don’t require massive amounts of green energy to scrub the atmosphere.
