The rest of the quote you began continues:

"On the other hand, Perrault noted that 'Epoch AI independently estimates Grok 4’s emissions to be significantly higher at approximately 140,000 tons of CO₂.'"

I realize these are still estimates, but when the other independent analysis nearly doubles the outcome I'm not left feeling optimistic. One could argue some numbers from others are underestimates... which of course just bums me out all the more!
