U.S. gas taxes rank among world’s lowest

Even with Delaware Sen. Tom Carper’s proposed increase of the federal gas tax from its current 18.4 cents per gallon to 34 cents over the next four years, U.S. fuel taxes are still among the lowest in the world, according to data from the Tax Foundation. When the average state tax is included in the figure, U.S. taxes are less than half of the next lowest global tax rates.
