Environmental pollution has become a huge problem in many parts of Africa. Until a few years ago, the prevalent response of African governments was the introduction of command and control instruments. This trend has changed and some African countries are now turning their attention to the use of economic instruments including taxes. One of the countries that has introduced environmental taxes is Ghana. This paper analyzes the policy processes related to the emergence and implementation of three environmental taxes in Ghana, namely, taxes on plastics, overaged vehicles, and petroleum applying a public choice approach as the framework of analysis. Overall, we find that all actors behaved as proposed by public choice resulting in environmental tax designs that do not follow what economists consider optimal. Nevertheless, the taxes contributed to mitigate environmental problems, partly because a share of the tax revenue was used for this purpose. Thus, environmental taxes have the potential to mitigate environmental problems in Africa provided functioning administrations are in place. This is, however, currently not the case in many African countries.
