How do you change eco footprint in apartments?

Thanks for the advice! I would be very happy if the footprint only stayed neutral and hope I don't have to do a lot of renovations since I like my apartments as they are :D And there isn't that much variation if I can only use build/buy from eco lifestyle to only stop the neighborhood going industrial...

I hope my other neighborhoods aren't going down the same speed... Well, I must play some more to see and then maybe search some more info if they really are.
