Editorial

The 2030 Agenda for Sustainable Development emphasizes the importance of implementing equitable and effective measures to tackle the pressing challenge of climate change. The deployment of low-carbon technologies such as solar panels, wind turbines and lithium-ion batteries, which are highly mineral-intensive, will drive a mining boom in Latin America and the Caribbean.

 

The presence of lithium, copper, nickel and other minerals in the countries of Latin America and the Caribbean presents opportunities to develop the mining sector, diversify production, add upstream and downstream value, establish networks of local suppliers and enhance regional integration and cooperation. However, the reliable and affordable supply of these resources is subject to supply-side risks and demand-side pressures.

 

Leveraging the opportunities for mining in the region and minimizing potential risks will require a strategic, long-term vision that focuses on economic and social development and environmental protection. To facilitate a regional transition towards more sustainable extraction models, there is a need for the mining sector to increase the use of renewable energy, implement integrated water resources management, adopt new circular economy models, recycle waste, reduce the carbon footprint and safeguard critical natural resources.

 

This bulletin examines opportunities and challenges in Latin America associated with the growing global demand for the critical minerals required for the energy transition and electromobility, in order to spur debate on the role of metals and minerals for a more productive, inclusive and sustainable development model.

 

Main article

The transition to renewable energy sources and the growth of electromobility are driving an increase in demand for key minerals, including lithium, copper, cobalt, graphite and nickel. These minerals are essential for manufacturing wind turbines, solar panels and the high-capacity batteries used in electric vehicles and energy storage systems, for example (see box 1 on lithium-ion batteries).

Box 1 

Advantages and disadvantages of lithium-ion batteries

The performance of lithium-ion (Li-ion) batteries varies depending on the chemistry of their main components (see table 1). These batteries function on the basis of an electrochemical oxidation-reduction (redox) reaction and are usually composed of one or more cells, each with two metal poles (electrodes): the cathode or positive pole and the anode or negative pole. They also contain an ionic conductor (electrolyte) that may be a liquid, solid or hybrid (gel), and a membrane to separate the poles. The cathode may contain varying amounts of lithium and other minerals (cobalt, iron, manganese or nickel) and the anode is usually made of some type of carbon (graphite), but it can also be made of another metal or metal alloy (lithium, tin, silicon or titanium). The ionic conductor usually contains lithium salts, and the dividing membrane is micropermeable to enable lithium ions to circulate between the poles.
