At the latest after decarbonization of the power grid (yes I am laughing as I write this), we will want to remove CO2 from the air which was emitted 50 years ago. Also I would like to point out that the IPCC scenarios about reducing global warming already include carbon capture. Plans to remove CO2 from energy production till 2035 already only work under the premise that we actively start removing CO2 from the atmosphere simultaneously.
