As a result, annual increases in vehicle miles traveled (VMT) in LDVs average 0.9% Among the more detailed transportation projections in AEO2014 are: LDVs powered by gasoline remain the dominant vehicle type in the AEO2014 Reference case, retaining a 78% share of new LDV sales in 2040, down from their 82% share in 2012.
Factors influencing the decrease included: In 2011, transportation-related carbon dioxide emissions fell primarily due to higher fuel costs, improvements in fuel efficiency, and a reduction in miles traveled. In 2010, the price of regular gasoline averaged $2.78 This contributed to a decline in gasoline consumption of 2.9%
During the late innings of the ICE-age (as in the Internal Combustion Engine age) it has become clear that feeding gasoline and diesel to the next billion new cars is not going to be easy, or cheap. The cost to operate an EV, per mile, is already well below the cost to drive a standard ICE-age model, and the advantage is likely to widen.
The decrease in CO 2 emissions from fossil fuel combustion was a result of multiple factors, including a continued shift from coal to natural gas, increased use of renewables in the electric power sector, and milder weather that contributed to less overall electricity use. above 1990 levels in 2007. above 1990 levels in 2007.

With motor sports moving hard and fast toward electric drive, a friend recently told me that electric drag-car racing just wouldn't be the same without the deafening roar of combustion engines and the smell of "nitro" fuel. With electric vehicles, however, calculating efficiency is not so simple. She's 90 years old.
The California Air Resources Board (CARB) announced that greenhouse gas emissions in California in 2016 fell below 1990 levels for the first time since emissions peaked in 2004—a reduction roughly equivalent to taking 12 million cars off the road or saving 6 billion gallons of gasoline a year.
