By any chance do you remember the source for that? Googling "1000 tokens emits 8.3g CO2" only gets me this thread.

The search was "ai tokens per tonne co2" and the "1000 tokens emits 8.3g CO2" bit was my paraphrasing from the AI overview.

This article [0] mentions "8.3g CO2" but it's linked source [1] uses a different number - 4.32g. Perhaps revised after publication.

I ran the search again and got different numbers... I'm sure the real numbers will be changing quite a bit over time too.

		Oh, I thought you meant "Google, the company, published this number" (which I would have been very interested to read), not "Google, the search engine/sketchy llm, returned this result". Fair enough.
