Need in-depth info about pollution

[morchuflex]

Hello.

I have two questions about pollution:

1. Which buildings produce pollution (C3C)? It seems that commercial docks do generate 1 pollution (not mentionned in civilopedia). Furthermore, I've read but not tested (because I never drag the game that far) that research labs do pollute. What kind of an absurdity is that?

2. What does each pollution icon represent?
Of course, I understand that the more icons, the more likely it is that a tile will be polluted. But what percentage are we talking about? 5% per icon?
In an old game, I once had a huge (25 pop), highly-productive city that polluted one tile almost every turn. But I can't remember how many pollution icons it had.

Any help?

1. Factories (2), manufacturing plant (2), coal plant (2), research lab (1), offshore platform (2), airport (1), iron works (4), commercial dock (1).

I think free research labs given by The Internet don't pollute, but don't quote me on that.

I don't think the exact formula for when tiles are polluted is known. I think we just have to stick with: the more icons, the higher the chance.

That's correct. I have experienced too that cities don't generate pollution from their free research labs.

Also, any population point above 12 will generate a pollution point. So a size 13 city with no pollution-producing improvements will generate 1 pollution point, a size 14, 2, a size 20, 8.

If you want to cut down on pollution, Mass Transit will reduce any pollution due to population down to 1 (so a size 20 city with no pollution-producing improvements will generate 1 pollution point), and a Recycling Centre does the same thing for improvements. Build both, and even your biggest, baddest cities will produce only 2 points of pollution...

So if you went into the editor and gave Mass Transit a -1 pollution value and Recycling Centre a -1 pollution value would that eliminate all pollution once you build these improvements (as needed)? I'm going to try that in my next game. You see I get rid of RRs in all my games because it takes away all strategy from the game but not having RRs makes cleaning up pollution a pain.

Woah, I would never have the courage to do that. Without RRs transportation is a pain.

About research labs generating pollution, I think that is logical with all the chemical testing and such.

Getting rid of railroads gets rid of your food and production bonuses. How will you keep up with the AI?

I think he means getting rid of the RRs completely, so the AI doesn't get to build them either.
