Just a few inputs...
I turned off the eco effects in game setting, but I think this only takes away the animations in world/hood view, and not (always) in each lot. Recently I visited a lot where the pollution was real bad. I like this, because the pollution on lot level will normally make sense, being in cities or hoods with a high level of commerce. Specific items (ie fireplaces) will add to the pollution "score", but it also depends on what lots you actually play. If there is a "bad" lot in the hood, but your sim frequently visit the good lot (say a park) the negative pollution will take longer to tick in - if ever.
For NAPs, which I like but dislike how they were performed - with no customation per NAP (whish we could have created custom NAPs!). So while I use them for my kingdom's political system, I turn of the voting. Seems like no changes are made to current NAPs but you will still get the weekly notifications "voting is open/closed". When installing the pack NAPs will probably be assigned to some hoods, but you can easily cheat them off by shift-clicking the mailbox (must be done once per affected hood). Even if NAPs feature is restricted in your game settings, sims will keep earning "influence points" which is a sort of community currency used for voting. Unfortunately there is no way to spend those points on anything else.
I like many features of the ECO pack, especially the many new ways to make a living from home, also CAS is good, and I find the BB good because it represents something different in the game. However, this is one of the packs that I could have survived without, I'm simply not enough into ECO to explore all the features.
