How can you decrease CO2 concentrations?

In: SciTech › Science › Chemistry › CO2

Rate This Answer

CO2 To be able to reduce carbon dioxide concentration by Carbon sequestration back to pre-industrial levels, (390?280 ppm)/390 ppm/(50%/100) = 70% of all the CO2 in the air needs to be removed, where 50% is the percentage of carbon dioxide residing in the atmosphere (and not in the oceans), removing about (390?280 ppm)/(50%/100) = 0.03% of the air — an immense task.[edit]
