It HAD an ESI of 0.98 1075 years ago. By now, the inhabitants have burned through all their fossil fuels and then annihilated each other with nuclear weapons leaving the planet in both a long-term nuclear winter and with a runaway greenhouse effect. Its ESI must be at least 1.0 by now.
I'm not sure what fossil fuels and nuclear weapons have to do with this but 1075 years isn't a very long time. There may not be intelligent life on the planet yet.
