Civilization can and must be climate gas neutral. Can be accomplished through massive build-out of geological-time CO2 sequestering, financed with global taxes on greenhouse gas emissions and international agreements to the same effect.

End-state will still have lots of economic processes that require releasing greenhouse gases to the atmosphere, even new or novel ones. But these will be offset by the sequestering paid by their taxation.

Taxes will shift greenhouse gas emissions to no-emission alternatives where that's practical and desirable, probably meaning most of them in the end.
