The purpose of this paper is to provide a supply and demand analysis with regard to cobalt. This work considers the future of cobalt mining. In order to achieve this objective, several aspects of the mineral are presented. On the one hand, the supply side is analyzed in depth. On the other hand, in terms of the demand side, I will examine the different end uses of cobalt. A linear regression allows us to forecast the future production of cobalt based on mining. In order to undertake such an analysis, the electric vehicle (EV) analysis of the International Energy Agency (IEA) is used. The results presented are based on two scenarios. The first one is the New Policies Scenario. The second one is the EV30@30 scenario. The results show that, in the future, cobalt production will increase. It will be partially caused by the likely increase in the EV sector. Then, the results obtained are discussed. There exist several papers which also forecast a growing cobalt supply. Finally, a section is dedicated to business ethics. It brings to light the role of companies in the responsible production of cobalt.
