DOE: in 2018, 27% of new light-duty vehicles in US had fuel economies > 30 mpg

Green Car Congress

In 2018, 27% of new light-duty vehicles sold in the US had fuel economies of more than 30 miles per gallon (783 l/100 km), according to the US Department of Energy (DOE). By contrast, none of the light-duty vehicles produced in 1975 had fuel economy greater than 30 miles per gallon (mpg). In 1995, 4.4% In 2018, 2.4% Source: U.S.

They further estimated that roughly one-fifth of the savings can be attributed to gasoline price increases over the period and four-fifths to fuel economy and greenhouse gas (GHG) standards. Estimated attribution of fuel savings due to fuel economy improvements to light-duty vehicles since 1975. Greene et al. has almost doubled.

EPA proposes new GHG rules for light-duty vehicles; updating emission standards for heavy-duty trucks

Green Car Congress

The US Environmental Protection Agency (EPA) released a proposed rulemaking for model year 2023-2026 light-duty vehicle greenhouse gas emissions standards, and outlined its plans to initiate a subsequent rulemaking to set standards for MY 2027 and beyond, to speed the transition of the light-duty vehicle fleet toward a zero emissions future.

ORNL researchers use stop-light cameras to reduce fuel consumption of less-efficient vehicles via traffic management

Green Car Congress

Approximately 6 billion gallons of fuel are wasted in the US each year as vehicles wait at stop lights or sit in dense traffic with engines idling, according to US Department of Energy estimates. In a real GRIDSMART system, they just send vehicle data to a controller, and it says, ‘I’ve got cars waiting, so it’s time to change the light.’

ICCT calculates consumer benefits of increased efficiency in 2025-2030 light-duty vehicles in the US

Green Car Congress

A new report from the International Council on Clean Transportation (ICCT) estimates Consumer benefits of increased efficiency in 2025-2030 light-duty vehicles in the US. 4%, 5%, and 6% compounded annual reductions in CO2 targets for cars and light trucks for 2026–2030, compared against vehicles that meet the adopted 2025 targets.
