From 1970 to 2010, vehicle distance travelled in the US increased by 155% (from 1.674 trillion km to 4.260 trillion km); however, because vehicle load (i.e., Sivak found that while the vehicle fueleconomy of the entire light-duty fleet improved by 40% (from 13 mpg US to 21.6 occupants carried) decreased by 27% (from 1.9
users pay for the construction and maintenance of roads via a federal fueltax. Revenues from the tax go into the federal Highway Trust Fund, which is independent of the General Fund; every five years or so Congress passes an authorization bill to allocate these revenues. States use similar mechanisms. —Huang et al.
IEA fueleconomy readiness index status, 2010. New propulsion systems requiring new fuels, such as plug-in electric vehicle systems and fuel cell systems, are beyond the scope of this technology roadmap and are treated in separate roadmaps. Average fueleconomy and new vehicles registrations, 2005 and 2008.
The economy-wide CO 2 prices applied increase the cost of driving only marginally with respect to the business-as-usual case. Direct transportation (fuel) taxes generate the greatest reductions in CO 2 emission from transportation, achieving CO 2 emissions at 86% of 2005 levels by about 2025.
Increased sales of electric vehicles allow automakers to sell more low-fuel-economy vehicles and still comply with the federal standards that govern the average fueleconomy of the vehicles they sell (known as CAFE standards). Indirect effects. That effect may be large. Cultivate local PEV clusters.
Since some 36% of diesel is used off-road, such as on farms, by manufacturing, industrial and commercial ventures, and boats, a fueltax for road use would impose an unfair burden onto these sectors, the government says.). In New Zealand, diesel and electric-powered vehicles pay for their road use through road user charges.
Projected cumulative greenhouse gas reductions from 2010-2050 by strategy category under maximum deployment scenario. Strong economy-wide pricing measures (such as a $5.00 per gallon fueltax by 2050) could result in an additional reduction of 28% in GHG emissions. Data: Moving Cooler.

The results of the report’s plausible yet aggressive scenarios for the United States show the potential for technological improvements to more than offset fleet growth and, by 2050, reduce fuel use and GHG impacts by up to 50%. Includes vehicle weight reduction: at constant acceleration capability.
