IIRC, Microsoft, which is hosting OpenAI, has already their server farms on carbon-neutral electricity, and is heading towards full carbon neutrality on the lifecycle of their server farms.
So doing stuff yourself is less carbon efficient than letting ChatGPT do its job.
As for calculating co2 pollution into the prices - we're slowly doing that, e.g. EU is setting up its carbon tax that applies to companies abroad.
The issue is that if we were to instantly include true costs of carbon removal into everything, the economy might collapse at worst, and at the least poor people might not afford food, heating nor other basic necessities any more. It will take time to do it sensibly.
I'm skeptical that industrial civilization can exist at all (at least on anything like a billions-of-people scale) with priced-in emissions, but I guess we'll see. Widespread famine and suffering are in store one way or the other (either because of climate change, or because of what we will need to do to fight climate change).
