A ton of corn costs about $166, let's say that's half carbon. So each gigaton will cost about $300 billion, and thats just to buy the corn, not including the digging, etc.
You'd need to collect about 900 gigatons to return the atmosphere to preindustrial CO2 levels.
- falsestprophet 10y agoThe cost of corn stover (leaves and stalk) is $40-$80 including transportation it's about $100 per ton [1]. So, that's $90 trillion at US biomass production prices (assuming that much biomass was available) or 1.2x world annual gross world product [2]. Still $90 trillion seems like a lot.
