Taxes on Fuel and Vehicles
Taxes on fuels are an attractive source of revenue. They amass vast sums, amounting to $1.2 trillion in 2004, or 10.8% of all revenues collected by governments. They are easier to collect than other taxes because they are assessed at refineries or large wholesalers, which are few in number. People are somewhat less adverse to fuel taxes than other taxes because a major portion of these revenues is spent on highly visible infrastructure projects. Road signs in construction zones along U.S highways proudly announce “Your Tax Dollars at Work.” The public also recognizes that, in addition to high fuel prices, high fuel taxes discourage superfluous driving as well as encourage the purchase of more fuel-efficient and less polluting vehicles.
The average cost of extracting, transporting, and refining gasoline and diesel fuel in 2006 was $0.53 per liter ($2.01 per gal) for gas and $0.59 per liter ($2.23 per gal) for diesel.  Average prices at the pump, however, ranged from $0.02 to $1.90 per liter ($0.08 to $7.19 per gal) in different countries, depending on fuel subsidies or taxes. Countries subsidizing fuel are, in general, major oil exporters. Most other countries tax fuels, often at rates higher than other goods.
Taxes on fuels are only the beginning of revenue collection. Supplemental taxes on vehicles are nearly universal, although there is little uniformity among countries or sometimes even among regions within a single country. Most governments assess a value-added tax or sales tax at the time of purchase that is based on a percentage of the purchase price. Most also assess a license or registration fee at the time of purchase; this tax often varies with the value of the vehicle and some measure of its fuel consumption. Finally, most assess an annual circulation or road use fee; this tax is often keyed to some measure of its fuel efficiency.

Taxes on fuel might be part of an ecological policy aimed at reducing negative environmental impacts of excessive fuel use. One such impact, human activity related climate change, might be reduced by taxing fuels. Non tax policies, for example, the policy of requiring vehicle manufactures to increase the fuel efficiency of their offerings, may have undesirable effects without taxing fuels to mitigate the rebound effects. Rebound effects may include increased use of total fuel because of the proliferation and increasing employment of those technologies.
