Pollution before anyone has Industrialization

[Tristan_C]

It can reduce pollution to zero if the city has 40 smokestacks (100%), or not reduce it a single point when the pollution is positive (0%), depending.

Thanks for clarifying that! I Always thought it was 67% no matter what!

Um, sure, no problem. You might want to read this thread. I posted the formulas.

Whether power is dirty or clean has no effect if there is a recycle ctr., as indicated in the formulas above

Ah, yes, I also knew that empirically and still somehow bungled it up. It figures, the modifier in that formula can't be both 2 and 3. So 'clean' power is only useful for cities that don't produce enough shields to require a rec. ctr. but still spawn some pollution after building mass transit.
