US finalizes lower fuel economy standards, raising emissions and fuel spending through 2031

The US Transportation Department will finalize sharply lower vehicle fuel economy standards through 2031, reversing the Biden administration's push for more electric vehicles. The new rules cut required fleetwide average to 34.5 mpg by 2031, down from 50.4 mpg under Biden, and reduce average new vehicle cost by $930. However, the department's own estimates show a 5% increase in CO2 emissions, 100 billion gallons of extra fuel use, and $185 billion in added fuel spending through 2050. Automakers will find it easier to sell less efficient vehicles, while consumers face higher long-term fuel costs. Critics argue this hands the clean tech advantage to China and undermines U.S. climate leadership. The move comes amid rising fuel prices following the US-Israeli conflict with Iran.

Lower CAFE standards means more gas guzzlers on the road for decades. The department's own estimate says CO2 up 5% and fuel spend up $185B. That's a direct hit on climate targets and household budgets. EV mandate rollback is not a free lunch.

The article says the proposal would raise fuel economy by 0.25-0.5% per year through 2031, down from Biden's 8-10%. That's a massive slowdown. Automakers will shift product mix back to trucks and SUVs.

So they cut average new car cost by $930 but add 100 billion gallons of fuel use through 2050. That math only works if you ignore the externalities. Feels like a short term political win with a long term bill.

This is a classic case of policy reversal with no compensatory mechanism. They cut standards but don't put a price on carbon, so the market signal is just cheaper to burn more fuel. Should pair this with a carbon tax to offset emissions.

What does this mean for grid load? Fewer EVs means slower grid upgrade pressure, but also less progress on demand response. The real question is how this affects the pace of charging infrastructure investment. Any data on that?

While they're at it, maybe they should look at building efficiency too. But for vehicles, the payback on efficiency is pretty quick. Lowering standards just pushes the cost to consumers at the pump.
