Fuel tax
A fuel tax (also known as a petrol, gasoline or gas tax, or as a fuel duty) is an excise tax imposed on the sale of fuel. In most countries the fuel tax is imposed on fuels which are intended for transportation. Fuel tax receipts are often dedicated or hypothecated to transportation projects, in which case the fuel tax can be considered a user fee. In other countries, the fuel tax is a source of general revenue. Sometimes, a fuel tax is used as an ecotax, to promote ecological sustainability.
