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

A team from the University of Tennessee and the National Renewable Energy Laboratory (NREL) has the fuel savings due to fuel economy improvements over the past 43 years amount to approximately two trillion gallons of gasoline. Greene et al. Fleet-wide fuel economy gains produced large fuel savings.

EPA annual report on CO2, fuel economy and technology trends finds 2012 heading for all-time best; rapid adoption of new technologies

Green Car Congress

Adjusted CO 2 emissions and adjusted fuel economy, MY 1975-2011. The report finds that CO 2 emissions rates and fuel economy values reflect a very favorable multi-year trend beginning in MY 2005. The fleet-wide average real world MY 2011 personal vehicle CO 2 emissions value is 398 g/mi and average fuel economy is 22.4

EPA Trends on EVs and PHEVs; beginning of a “measurable and meaningful impact” on new vehicle fuel economy and emissions

Green Car Congress

The agency’s reasoning was that since alternative fuel vehicle production has generally been less than 0.1% of total vehicle production until very recently, the impact of excluding alternative fuel vehicles was negligible. In the analysis, EPA uses overall fuel economy in mpg equivalent (mpge) and tailpipe CO 2 emission values.
