As the global energy transition accelerates, demand for critical minerals and metals will also increase significantly. The International Energy Association (IEA) estimates that attaining targets for clean energy set by the Paris Agreement will quadruple the demand for clean energy minerals by 2040. However, projections of current supply, including mines presently under construction, will not meet anywhere near the demand needed. Africa holds at least one fifth of the world’s reserves in a range of critical minerals and transition metals, and over the last decade, East Africa has been experiencing a rapid expansion in the mineral sector. In Tanzania, the mining sector’s contribution to the Gross Domestic Product (GDP) has been increasing yearly to become the economy’s leading foreign exchange earner. The opportunity for Tanzania to harness and accelerate its position as East Africa’s mining hub to the world by supplying vital products to global markets from its mining and exploration activities in the support of the green transition is timely.
