US: EPA finds no progress in vehicle efficiency as automakers sell more big models
(ACEEE blog, 12 Dec 2022) The American Council for an Energy-Efficient Economy released the following statement from Avi Mersky, senior transportation researcher, in response to the 2022 Automotive Trends Report published on Monday by the Environmental Protection Agency (EPA): “The bottom line is fleetwide fuel economy didn’t improve. That’s bad news for drivers at the pump and for the climate.
“Some models got more efficient, but with the automakers marketing large SUVs so heavily, they’re taking up more and more market share. The manufacturers are canceling out all the efficiency progress as they sell more large vehicles. And it’s completely allowed under the federal rules.
“There’s another problem, too: Nearly all automakers used emissions credits from earlier years in the program to undershoot this year’s fuel economy target.
“The EPA is going to need to learn from the lack of progress here and tackle the relentless upsizing of vehicles and rampant use of credits in its next standards.”
