That isn't to say that reducing CO2 emissions isn't worthwhile, only that zero is not achievable or necessary. We shouldn't let perfection be the enemy of the good.
We'll be carbon neutral when we eat photons and exhale oxygen, or never, whichever is first.

I'm hesitant to get off track, but to me the simplest way to be carbon neutral or even carbon negative is to build mass scale atmospheric carbon scrubbers and put them as close as possible to the biggest sources of CO2 production man or natural. This may very well cost billions if not even a trillion, but that's less expensive than something like the green new deal by a factor of 10. That is based in current costs of the technology which just like batteries or anything else will get better with time and scale.
