EPA expected to announce rollback of Obama-era mileage standards
By: jbr

The Environmental Protection Agency is expected to announce steps today that will roll back the strict, 54.5 mpg fuel economy rules set to phase in between now and 2025. The move would eliminate one of President Barack Obama's key climate change initiatives and set the White House on a collision course with states that have already pledged to follow the tighter regulations.

Fleet mpg rules, along with coal emission regulations, are why we can breathe again in East TN.

diminishing returns

Submitted by Up Goose Creek on Tue, 2018/04/03 - 8:33pm.

The combined mpg of my capacious Ford "prius" has been 39.5. For 12K miles it uses only 83 more gallons (303) than the proposed 54.5 mpg (220).

Go 15 mpg in the other direction and a typical 24.5 combined mpg vehicle uses 187 more gallons (490).

If you get the old 12 mpg rust bucket off the farm and replace it with a blingy 22 mpg ecoboost Ford that's an annual savings of 455 gallons right there!

The point of diminishing returns is 24 mpg. I could never recreate the calculus but I kept the chart to remind me.

Anyhoo - I always thought that 54 mpg was unrealistic as an average. Save the earth - plant more trees. Resurrect cash for clunkers. Outlaw visible exhaust.

As for air pollution... I could stand behind the tailpipe of my high mpg 93 Saturn and smell more pollution than my 06 truck with much lower mpg but a "greenway" designation.
