As far as I can see the only practical widespread carbon capture process we have is plant growth (and pyrolisis). That might be possible for some fraction of global emissions (maybe 5-10%), but once you get above that you have to be cutting down quite significant amounts of forest. It all seems like a lot more work than just not extracting the carbon from the ground in the first place.
