Carbon tax pricing and the social cost of carbon: the case in the South African motor vehicle manufacturing industry

Abstract

Since the implementation of carbon tax on motor vehicles in South Africa during 2010, the pricing of the tax has never been challenged or assessed. The purpose of this study is to gauge the reasonability of the carbon tax price in South Africa as applicable to the motor vehicle manufacturing industry. A detailed review is performed to determine the adequacy of the carbon tax price by comparing the social cost of carbon from motor vehicle emissions against the revenue raised from carbon tax levied on motor vehicles in the same period. Empirical research includes an exploratory questionnaire into the adequacy of the carbon tax price in South Africa with input data from multinational motor vehicle manufacturers operating in South Africa. The findings from the literature review confirm that although the respondents do not consider the level of carbon tax price as adequate to be relevant for the social cost of carbon, the revenue raised from this tax exceeds the social cost of carbon leading to the conclusion that the tax is adequately priced.
