Is it actually better in a CO2-emissions sense to use a 90% efficiency natural gas furnace, or to use a 300-400% efficiency heat pump running off a grid that is 2/3rds (on average) powered by renewable sources? Not making a statement or asking for a guess: asking if anyone has done the math on this.

Getting rid of natural gas is environmentally foolish, at least until we reach the fairy tale world where nothing is burned for energy. Today though? This idea of "no natural gas", harms the environment.
