Emissions reduction efforts would be better spent ensuring repairability. The sunk cost emissions of landfills filled with junk created by planned obsolescence is much worse.
Diesel pick ups are not practical vehicles. Let's be honest, it's a hobby. It's always going to be niche and cutting down the last 10% is always the hardest. General aviation still uses lead.
Not sure what your point is, I was talking primarily about Class 8 heavy duty commercial trucks (semi) and other medium duty commercial use.
All the stuff that makes up emissions gear is highly recyclable and in fact some of it very desirable which is why people are getting catalytic converters stolen. So I do not worry about it filling up a land fill.
I also don't worry about EV batteries filling landfills because again they are very high grade ore for new batteries, once we have enough in circulation we no longer need to mine much lithium or rare earth.
I agree it should be reliable and repairable and forcing the manufacturers to have very long warranties on it seems like a good way to do that, having followed the various generations of DEF systems for the last decade the manufacturers have been making big strides because it costs them otherwise and has.
I also think airplanes using lead is stupid, but that is a fraction of even private diesel pickup usage let alone commercial trucking. Diesel pickups are at least 10% of all pickup sales now days.
