What about all the pollution involved in making all those trucks and truck parts that have a lot less lifespan these days and energy consumed manufacturing them?- I guess that does not count?

What about the energy and fuel consumed delivering them?

What about all the pollution in making and using all the extra fuel that trucks simply waste in attempts to be compliant like lower fuel economy and fuel used to do regen.

What about all the large amounts of energy consumed in the making the giga-tons of manufactured urea every year for all these vehicles to consume? - What about the plastic containers and all the crap that went into making them too? - What about the fuel consumption of the delivery trucks used to transport and deliver it? - and the extra weight from having to carry it on your truck?

BTW, My take on it is that none of these egr systems themselves work to reduce anything any ways.

Starve the cylinders to not burn the fuel as efficiently in hopes to reduce NOx gas. It creates unburnt fuel molecules called soot. Trap that soot, then use even more fuel to burn it off at a later time. - At the end of the day, after the regen process, this cannot possibly be LESS, but only MORE. The math and logic just does not add up at all. Add in the use of urea to lower NOx, that is great, but all the energy in making and transporting the urea itself more than overwhelms the environmental savings if you ask me.

SCR systems also increase CO2 emissions. That can't be good either.

And .. What about the unused NH3 Amonia produced during the SCR heatng process in the SCR can? Last I checked -->

Amonia contributes to acid deposition and eutrophication, which in turn, can lead to potential changes occurring in soil and water quality. The subsequent impacts of acid deposition can be significant, including adverse effects on aquatic ecosystems in rivers and lakes, and damage to forests, crops and other vegetation.

The only real solutions I see would be to use a LOT less energy overall instead of playing this big game of save a little NOx gas here to consume it over there. Maybe to add to that, using and making equipment that simply is a lot more reliable and more fuel efficient above all else. I would think that if a truck could last say 25 years and be maintainable, that this would dictate a LOT less environmental impact alone.

What about all the Osmium (platinum) that is now known to be starting to cover the entire earth that is emitted via catalytic converters and DOC's from both cars AND trucks at higher and higher levels? - I have even seen youtube videos where people sweep up dust along the freeways and recover the platinum it is getting so bad.

Platinum/Osmium, even in very very low concentrations from what i have read can cause lung congestion, skin damage, severe eye damage, increased cancer rates in all major cities and surroundiongs, etc.

Am I missing something here?

I am not a tree-hugger by any means, but I see no overall environmental gains whatsoever except to line people's pockets. These standards only sere to let the engine makers sell expensive components with rare metals in them that constantly fail + line the oil makers pockets from all the wasted, extra fuel consumption. I find it an awful coincidence that as engines have become more efficient over the years, there is always some excuse for the EPA to ensure the consumers of fuel see none of those gains,.. all in the name of better emissions!.
