The average car purchased in 2023 emits higher levels of carbon dioxide (CO₂) than its 2013 equivalent. This is due to the large proportion of SUVs in the mix, which tend to be bigger and heavier.

Which pollutes more: a new SUV or a 10-year-old conventional vehicle?

Rollie Williams and Nicole Conlan from Climate Town on YT talked about this on their podcast, The Climate Denier's Playbook, a few weeks ago.

Car companies, at least domestic ones, are subverting fuel economy rules by making cars "like trucks" due to a loophole in the code about Light Duty vehicles (SUVs are light duty trucks and hence get around requirements that other, smaller light duty vehicles have imposed on them).

It's the same reason we see bigger and bigger trucks that look like tanks and that you can't see children from. Those bigger vehicles require bigger engines to move, hence more greenhouse emissions.

It just goes back to H. W. Bush's statement that "the American way of life is not up for negotiation" in addressing climate change. It's like everything (that doesn't threaten profits too much) is up for negotiation, except for the primary driver of the problem.

Iirc, the "light Trucks" is only in US law through, right?

Correct, but companies prefer to minimize costs to maximize profit, so if a large portion of their total markets changes rules, companies will likely adjust so that their products are all the same for all markets. A similar thing will probably happen with Apple once the USB-C thing goes into effect in the EU, affecting US and other markets.
