There is a big push for carbon capture and storage technologies, but so far AFAIK there is no real option that is more sustainable than alternatives (such as use of plants for carbon storage). The most efficient methods include capture at point of emission, which could have some use to mitigate industrial release. Some, are already in use for quite some time (at least the capture part, storage is a bit more iffy). In industrial use methods such diethanolamine treatment or selexol are in use, but they are not generally not feasible post-emission. There are efforts to push monoethanolamine capture as means to do that, but I am not sure how sustainable that method is. Last thing I hear was a rather mixed bag.
