Zero Pollution MOD?

[fighterfungus 70]

Hello I am having trouble, quite some time ago I downloaded a building that looked like a wind turbine that removed all pollution from my city and the only side effect was that should I delete it, the city would be plagued forever in pollution however I cannot for the love of me find a mod or building that does this, does anyone know where one might be?

 

thank you,

Try these:  

 

I swear by them.  They completely eliminate air pollution in your industrial zones (however, they do NOT work for traffic pollution).  You may have to plop more than one, but they are awesome.

That's the problem with the "eliminate all pollution" mods - if you remove them, pollution goes through the roof, and you can't get it back under control without replacing the mod.  There's a park that does this also, though I don't recall which one.  Maybe someone else remembers what these lots are.

 

On the other hand, to reduce pollution, a lot of the type recommended by lhrob is a good choice.  There are quite a number of this type of lot on the STEX.  As lhrob notes, they typically do not work for traffic pollution.  But if you're using the NAM, it gets rid of excess traffic pollution when the Clean Air Act is enabled; you can control how much traffic pollution is removed through the Traffic Simulator Configuration Tool.

I always found it odd that the NAM team tied their extra pollution reduction to the clean air act.  There is after all an ordinance for vehicle emissions (ordinance - car smogging), and that doesn't hurt industry to turn it on.  There is probably a reason for this, but idk what it is.

 

Personally I use god mode trees as my biggest pollution fighter.  Green band of trees around an industrial park will contain all of it's pollution.

[A Nonny Moose 8,261]

That must be an extra ordinance, because all I see is automotive emission reduction.

 

If you want to be nearly pollution free you need a good pollution fighter such as

[docj101 99]

Oops, sorry about that.  The in-game ordinance "Automobile Emission Reduction Act" is named "Ordinance - Car Smogging" in reader.  I only mentioned it because it would seem to make more sense linked to that ordinance, since it's already named for traffic.  The 'Industrial Dirty' demand effect is very negligible with "Clean Air Act" (~.3% demand reduction) so it really makes no difference.

The reason is that since the Automobile Emission Reduction Act does absolutely nothing to reduce automobile emissions, it is a prime target for modders who need a spare ordinance from which to create a custom one.  The Clean Air Act is far less subject to this type of modification.  Since the U.S. Clean Air Act covers vehicle emissions (and SC4 is at its heart, a U.S. game), this ordinance seemed like both a reasonable and safe place to make this modification.

Fair enough.

 

However I'm not sure what you mean when you indicate vehicle emissions are separate from air pollution.  Don't vehicles just cause air pollution?  How does the 'Automobile Emission Reduction Act' do "absolutely nothing to reduce automobile emissions", while 'Clean Air Act' actually does?  I mean in reader those 2 ordinances are almost identical, both reduce air pollution by 10%.  The only difference is one has a 'mayor rating effect' and the other a 'demand:ID effect'.  Could you help explain this phenomenon a bit more please?

 

For instance I use 'Automobile Emissions Reduction Act'.  When I turn it on I see the air pollution appearing to radiate from all networks diminish.  This diminishing air pollution effect could be interpreted by some as "doing something" not "absolutely nothing" to vehicle emissions.  I could be wrong, I'm just saying.

There are actually two types of air pollution in the game:  vehicular and non-vehicular.

 

Don't vehicles just cause air pollution?

 

Not the same kind that buildings cause.

 

Both the Clean Air Act and the Automobile Emission Reduction Act reduce air pollution by using the Air Effect property.  This property has no direct effect on vehicle pollution, although if vehicle pollution is really bad and spills past the network boundaries, this property may help a bit.  But to really cut down on the heart of vehicle air pollution, you need to use the Traffic Air Pollution Effect property.  This property is not present in any of the standard ordinances, and was added to the Clean Air Act when used in conjunction with the NAM Traffic Simulator.

 

To demonstrate, here's a picture of a city with the standard NAM setting of the Clean Air Act with a 10% reduction, and the Traffic Air Pollution Effect with a 60% reduction:

 

The main pollution you see here is on the highways, which makes sense.  Now we'll take the same city, remove the Traffic Air Pollution Effect property, but set the Clean Air Act to a 60% reduction in pollution.  Here are the results:

 

 

As you can see, using the standard Clean Air Act to remove most of the city's pollution has essentially no effect on the networks.  (The reason that you see virtually no pollution outside the networks in both pictures is that I have various antipollution devices installed throughout the city.  Yet these have essentially no effect on the networks, as you can tell from the above picture.)

[docj101 99]

Oh I see what your saying now, both ordinances have "absolutely no effect" on the specific property "traffic air pollution effect".  At first I thought you were indicating that by default 'clean air' did have that property and 'car smogging' didn't.  They do affect 'air pollution', just doesn't affect the source: traffic, in any way.  The property had to be added to the ordinance to affect traffic specifically. 

 

Thanks for explaining that for me.  The property could have been added to car smogging just as easily, just it fit in either place and 'clean air' was chosen.  I have no gripes with that, as you said US's clean air act covers car emissions, so it's still realistic.  I stand by saying I think it seems more natural to have added the property to 'automobile emissions reduction act', but it makes no difference really.

 

Previously I was under the incorrect assumption that although traffic air pollution is it's own property, it was also part of air pollution in general.  I now see that air pollution being reduced by itself does not reduce the air pollution directly over networks caused by traffic.  The reason I thought it was reducing the traffic's pollution is because the ordinance was affecting the tiles directly next to the networks; the traffic still radiates the same pollution, it is just being cleaned up a little in areas between roads.  What is interesting about this is that if you eliminate the pollution either way. the RCI zones receive basically the same benefits, since none of them build directly on networks.

 

I made a quick example to show you what I was saying before.  I have turned off all pollution controls in the first picture, then I turned on car smogging alone in the second pic.  You can see that with the ordinance turned on the pollution is lowered in the areas between the roads, even in areas the roads are the only polluter.  This is what I meant when it could be perceived as though lowering air pollution alone affects traffic air pollution.

This topic inspired me.  I made a set of trees that are very strong pollution fighters.  They are planted and grow just like the default mayor mode trees.  They don't modify or replace the default trees.  Check them out if your looking for pollution for pollution control.  I had looked for trees that did this but couldn't find such a thing.  I tried to just modify the default trees, but that caused me problems.  These are not reliant on any dependencies.  They don't fight vehicle pollution, only building pollution.

I was under the assumption that traffic pollution also represented noise, so that would be the reason for the clean air act not to affect air pollution created by traffic, no?

no.  read above a bit more closely; we discussed that.  building air pollution is separate from traffic air pollution. 

 

traffic air pollution could "indicate" the amount of traffic noise because more traffic creates more of both, but it is not related directly.  air pollution, traffic air pollution, and traffic noise are all separate properties.

[z1 566]

Traffic pollution and traffic noise are completely separate.  Traffic pollution emanates from all vehicles if they are set in the traffic simulator to contribute to traffic; the property "Travel type generates traffic" controls this, and is set to "true" for all travel types except pedestrians.  Traffic noise is generated by pedestrians, cars, buses, and trucks that travel on all road networks excepting highways.  Reducing traffic pollution does not reduce traffic noise, or vice versa.

^ Pedestrians shouldn't be completely innocent.  The generate both Carbon Dioxide and Methane.

I hope this isn't too much to ask, but could you (or any modder out there) also made some sort of mod that reduces traffic pollution? So far, I haven't found such a mod. And I've used Google, Yahoo, and was even desperate enough to use Bing! Still haven't come up with anything.

If you have the NAM installed, then setting the Clean Air Act reduces traffic pollution.

[General Lee 9]

All right. I got the NAM version 32 installed (apparently the latest as of January 14, 2014). Now, how can I use this to eliminate all traffic pollution? I don't want to enable the Clean Air Act, as that would hurt industry, and Doc's Trees do a good enough job at that anyways. What I want to do is "turn off" all traffic pollution. How can I do this with the NAM?

[z1 566]

I don't want to enable the Clean Air Act, as that would hurt industry...

 

The effect of the Clean Air Act on industry is barely noticeable, if at all.  I've always used it in all my cities, and I've never had any problems with industrial development.

First, try just the Clean Air Act - it makes a huge difference by itself.  But if you really want zero traffic air pollution, you can use the Traffic Simulator Configuration Tool to set this quantity all the down to zero.  You still need to have the Clean Air Act enabled, though.

Well, it seems like I actually didn't need to even install NAM anyways (but will keep it installed as my "abandoned buildings due to commute" has decreased to zero). But after scouring the ST/Exchange, I FINALLY found what I was looking for. Here it is:  

 

The file you're looking for from here is the "Plugin_512Radius_NoTrafPollution.dat" file. Just plop that into your "Plugins" folder, and BAM! No traffic pollution!! This is good news for people who specifically hate traffic pollution, as it seemed like it was impossible to clean before. And it leaves your other air pollution in tact. But yeah, there are also other files found in the mod's .ZIP folder that changes the radius of other things as well; so its usefulness actually goes beyond just traffic pollution. But yeah, for those just incredibly FRUSTRATED with the "invincible" traffic pollution, I cannot recommend this enough! Not to mention you don't know how good it feels to finally find something after hours of searching.
