EVs and hybrids had a noticeable effect on US fuel consumption, says EPA

I like the idea of drawing the year to a close with some good news for a change, and I think maybe the US Environmental Protection Agency does as well. On Wednesday, the EPA published its Automotive Trends Report, which now included data for model-year 2022 vehicles.

And the data is good: record-low carbon emissions and record-high fuel economy, and the biggest improvement year on year for almost a decade.

For MY2022, the EPA says that the average real-world CO2 emissions for all new vehicles fell by 10 g/mile to 337 g/mile, the lowest average it has ever measured. Similarly, real-world fuel economy increased by 0.6 mpg for MY2022, to 26 mpg—this, too, is a record high and the single-largest year-on-year improvement for both CO2 and mpg for nine years.
