Starship gonna run on methane so most likely going to be carbon neutral.

Methane is a fossil fuel, so no way burning it is carbon neutral.

It'll be pretty big news if the methane they use to refuel Starship on Mars originates from a fossil source :D

Elon has discussed using the sabatier process on earth to create methane from CO2 to fuel it. Presumably the motivation would be a mix of PR and practicing for mars.

ISRU methane fuel for starship is going to be eventually done on earth (and mars) for carbon neutral starship / superheavy launches.

TL;DNR: If you take methane out of the atmosphere and you put it back in the atmosphere, the carbon footprint is neutral.
