Study estimates fuel economy improvements to US light-duty vehicles from 1975–2018 saved 2T gallons of fuel, 17B tons of CO2

Green Car Congress

Second, they estimated fuel savings using the FHWA data on vehicle miles, fuel use and miles per gallon (mpg). This step provided a limited validation of both the EPA’s new car fuel economy estimates and the FHWA’s total on-road light-duty vehicle fuel economy estimates. Two indirect effects were considered.
