I’m glad I’m an old fart and probably won’t see the results of the current administrations war on diesel, well war on anything carbon!
I do feel sorry for my kids, and even more so my grandkids
You can lay the blame wherever you wish.
However a bit of history...
Tier 4 Emission Standards was adopted by the EPA in 2004 under George Bush (Republican), to be phased in from 2008 to 2015.
The USA started phasing in ULSD in 2006 and 2007 under George Bush (Republican), which was a requirement for cleaner burning diesel vehicles.
Much of the development and implementation of the DPF, DEF and CATs came during the Obama years, but likely had been well under development during the Bush years.
Donald Trump was in office in 2017 to 2020, and the Republicans controlled both the House and the Senate in 2017 to 2018.
Cummins could have complained to Congress and Donald Trump that the emission standards developed a decade earlier were just to dang strict. Although doing so might have been an admission of their fooling around with the emissions system. And yet they didn't.
These aren't Biden policies, but rather policies that had been put in place long before he became President.
As mentioned earlier, the SMOG controls were started in the early 1970's, and incrementally got more and more strict due to problems with SMOG. If nothing had been done, with the current us population about 60% higher than in 1970, we could be in a world of hurt.
I remember when I was younger that older pickups routinely got less than 10 MPG. I'm glad that my newer RAM pickup gets better gas mileage than my little 4 cylinder Ford Ranger from a few years ago, while also being a large enough pickup to handle a decent sized trailer.
It is hard to deny that burning billions of gallons of fossil fuels is impacting our planet, whether it is from SMOG to climate change.
Politicians standing up on a stump can't simply wish away fundamental changes that are happening to our planet that will impact all of us and our progeny.
