Pollution from population

[spammikone]

I'm customizing my game where (hopefully) only nukes produce pollution, with workers not able to clear it. However it is a problem when your cities produce tiny bit amounts even you have all pollution reducing improvements. I plan to add some cap to pop limit if it removes the pollution. So my question is:

At which point your cities start to gain pollution from population?

More than 12 citizens.

You can add pollution reduction to all your buildings, but it will only cut it down to 1 for pop and 1 for buildings, so you still have a small chance of pollution when you have everything modded to reduce it.

Is it the population that matters or the fact it goes from city to metropolis??

It's linked to city size level 3, i.e. polution from population can only occur in a metropolis.

Per example in CCM you don´t have a real city-size 3 (limit for that size 999) and therefore no population pollution in the game.

That's good to hear. Also if I mod all pollution producing building to make 0 pollution, my cities won't produce pollution at all?

I guess there isn't any way to separate worker actions for clearing bombardment craters and pollution?

1: yes (buidding pollution = 0 and no real metropoplis city size)
2: no
