REFEREE REPORT
Does U.K or U.S have a right gas tax?
The Background and Motivation of the Study
The use of gas is currently the driver of most economies in many countries of the world.
Gasoline is used to drive machines that make work easier for a man especially in factories even
after entry of automation. The exploration of gas in the United States, as well as the United
Kingdom, has been ongoing for a long time. Just like any other product, there is the need to tax
them so as to enable the governments of the respective nations to raise revenue to finance its
