eli5: Why isn’t carbon capture used at emission sources?

Question

I know that there is ‘legacy carbon’ in the atmosphere that needs to get removed but why aren’t we leveraging carbon capture as part of industrial processes (e.g. at the factory’s smoke stack, for example). Or maybe we are already?

This is why Nuclear is the answer. No other energy source can account for every gram of waste they’ve produced in the history of their existence.
