The idea was that "clean diesel" emitted slightly less CO2 than the average gas powered vehicle. However, after the mass rush to buy diesel engines, it soon came out that not only were those reductions in CO2 somewhat overstated, but that diesel produced substantially more fine particulates, which strongly impacted urban air quality.

Wonder what the back story is there. Car companies sponsoring scientists to make certain findings.

Science is often corrupted by human agendas.

It was thought that diesel was cleaner way back in like the 80s. Another factor was regular gas still had lead, and diesel was for sure cleaner than leaded gas. That's why companies like Volkswagen went heavy into diesel cars back then, virtually all of their cars were diesel then. But as time goes on, science gets more tech, and learn more things.

Also, diesel back then was like half the price of regular gas.

A little more specific background;
"The Volkswagen emissions scandal, sometimes known as Dieselgate[23][24] or Emissionsgate,[25][24] began in September 2015, when the United States Environmental Protection Agency (EPA) issued a notice of violation of the Clean Air Act to German automaker Volkswagen Group.[26] The agency had found that Volkswagen had intentionally programmed turbocharged direct injection (TDI) diesel engines to activate their emissions controls only during laboratory emissions testing, which caused the vehicles' NO x  output to meet US standards during regulatory testing, while they emitted up to 40 times more NO x  in real-world driving.[27] Volkswagen deployed this software in about 11 million cars worldwide, including 500,000 in the United States, in model years 2009 through 2015."

I remember maybe 15 years or so back Korean car makers were selling LPG-powered minivans, but I guess that never truly caught on. The taxis run on LPG, which makes their trunks quite small.

Let's not forget that until 2019, the use of lpg vehicles was restricted to certain groups such as taxis, rental cars and the disabled.
Now, car makers are free to equip any vehicle with lpg and sell it to anyone.
About 2 million vehicles currently run on lpg and that number is expected to increase to 2.8 by 2030.
Also, converted cars have an extra lpg tank in the trunk. Very annoying that you can't load much cargo into taxis. But there are lpg cars that are manufactured that way so there is no visible fuel tank in the trunk.

Problem with LPG is that it needs to be compressed, which makes it harder to do everything cheaper than gasoline. Another advantage with gasoline is the power it produces, it maybe one of the least efficient combustible gases out there (something like 90% of it is wasted), but the power that it produces is unmatched.
