Abstract
Although much of the emphasis in taxation studies relates to a particular type of tax, the contribution of this paper by try to combine different taxes in one tax, whereby it was widely agreed that a mixture of the different taxes is regarded an ideal to reduced vehicle emissions. The study used existing empirical literature to prove that the taxes on vehicles alone are not sufficient to reduce vehicles externalities or short-term effects of these taxes, therefore there is need to impose a tax on emission source strongly due to the fact that many contemporary scholars proposed to taxation based on the actual emissions test, and car types/engines. The approach of the study was shown in the diagram which used to design a proposed progressive tax system which consists of a mix of different taxes. Therefore, the current study will add to the current literature, by provides background and details on taxes on vehicles and its operations. The aim will be to comment on them in terms of design and effectiveness in reducing emissions.
