How much do you care about pre emissions

[Yander]

Illinois does not do emissions checks everywhere. I’ve lived here my entire life and ever had one. The Chicago area does from what I know.

Same for Ohio.

I dont think anywhere in the SE US does emissions checks, although maybe Charlotte or Atlanta; but NC and GA don't, nor does FLa.

I'm not against clean air, but I don't think diesel engines are a problem for clean air. I know it does kinda hurt many of us to say, but maybe some of the enivro regs from 1980s have helped. Things are a lot better now; the problem is, IMO, the agency's can't help but want to inflict more stringent regs every year.

Now, CDL vehicles are always subject to getting pulled over and harassed.

IIRC one of the prime problems with DIESEL engines was what I call "the little old lady syndrome".
There was a saying, something like "sox, nox and rocks".
"Sox", or sulfur compounds, and "Nox", or nitrogen products, contributed to acid rain. There were places in the Northeast US where the acid rain was actually changing the hemlock forests. But they were invisible gases.
"Rocks" or particulates were VISIBLE. Every time someone "rolls coal" they are spitting out a lot of particulates. And in the northeast during the wintertime the snow captures and displays said particulates.
The "little old ladies" might not understand the chemistry behind acid rain but sure the h-e-double-L could see the "dirt" or "rocks" on the snow. AND for those that still practiced the ancient art of hanging laundry out to dry (after washing) KNEW it was making the laundry dirty while it dried.
And "little old ladies" DO NOT want to hang dirty laundry.
And you might not consider Virginia in the SE but most of it's NE section requires emission inspection.

The so called acid rain was shoved so far out of proportion and down our throats by idiots. When my kids were in school the "science" classes would go out and get water and soil samples and then test them for the acidity.
These liberal teachers would then carry on about the "acid" rain destroying everything in the Adirondacks. What a bunch of bull. I told my girls to get a sample from the dirt and pine duff under trees and then test that, lo and behold it's high acidity from the evergreens. And then I told them to check the acidity of the leaf mold under the big Oaks, damn oak leafs are also highly acidic how can that be.

Emissions lower the per unit contaminants, but since you have to use more fuel to accomplish the same task...the aggregate contaminants are still there on the production side of diesel fuel production.

So if the Saudi's are using more resources to get more fuel to market and then the US has emisisions...is there a per unit benefit globally?

Since most people can't think beyond what their two eyes see...they think the US is all unicorns and rainbows while ignoring the production side.

Lets not talk about where the EV energy comes from...but it's the same logic and thinking.

Yes Saudi's produce a lot of oil but couple of countries produce fair bit more.

Here is a list of top 20 oil producing countries as of Dec 2023

I'm definitely in the "Limit emissions" group. I grew up in the 60's and 70's in the Burlington, Vt. area. That was when smog started to hit.
From about 6th grade on the school I was in in Essex Center would take the "upper grades" to Ethan Allen Park for a beginning of the summer field trip. The park

View attachment 1068512
has a neat "fort" and the view from the top gives a LONG look down the Champlain Valley.

As soon as we were old enough we would climb up to the top and look down the valley. As I grew older the view was decreased by pollution. By the early 1970's during periods of calm air in the summer we could actually see like a fog of pollution rolling up the valley.

Then I joined the Army in '75, moved to Northern Virginia. Air pollution down here was so bad that we started having "smog days" by about 1979. Then it got better for a LONG time due to emissions equipment on cars.

What I think is unfair about all the emissions stuff is that I can run my 7.3L F350 (15MPG) and pollute all over, but if my Escape (~30MPG) burps it may not pass emissions.

California has had emission controls since the 60's and unleaded since 1973.

Heavy industry shuttered or leaving is credited for improving air quality plus the ban on wood heat, etc.

Sometimes you've got to know, that there's lots of stuff you don't know about... I'm no expert but some googling turned up lots of peer reviewed papers that show it was a real problem, maybe not in your backyard specifically, but in regions with landscapes that can't buffer large volumes of acid, acid rain made many lakes lifeless...

Acidic Deposition in the Northeastern United States: Sources and Inputs, Ecosystem Effects, and Management Strategies: The effects of acidic deposition in the northeastern United States include the acidification of soil and water, which stresses terrestrial and aquatic biota

I'm not for limitless pollution controls on everything immediately, but gradually moving towards less waste and pollution technology in general is a good idea.

Follow the money!
Very much of the so called acid rain was in fact from mother nature but that doesn't generate revenue or headlines.

Dead lakes were dead lakes, and now many are not after some reasonable pollution controls were put in place? Doing things better in terms of pollution costs somebody something, but looking back, don't you think its worth it in this case?
For me, in southern ontario, we used to have a big coal fired power plant and we used to have dozens of smog days bad enough to affect sensitive peoples health. Now the plant is gone and we have hardly any smog days. Maybe electricity is 3% more for having no coal plants, but that's fine with me....
Without your health, you have not much, so I thinks its worth working towards less polluting technologies.

Now, CDL vehicles are always subject to getting pulled over and harassed.

You got that right, every weigh station and roadside inspection always includes a check for emissions compliance and it's easy to tell, all a driver has to do is throttle up the engine and if black smokes comes out the exhaust, they fail. Of courde that don't apply to older units like I own. My Cat always smokes when throttled up but the inspectors know it'a pre emissions engine as they have not only the date of manufacture but a complete list of engines and injection systems on their laptop computers.

In my Western Star, all I have is a lap safety belt, no shoulder belt and they know that as well and never ask about it.
