As the world transitions towards cleaner energy, the demand for copper, fundamental to electric vehicles, grid infrastructure, and data centers, has surged, driving its price to over $10,000 a metric ton, a peak not seen in two years. This increased demand, juxtaposed with the challenges of securing new deposits amidst growing environmental and social concerns, preludes a looming shortage that could hamper the clean-energy shift. Furthermore, a report from PricewaterhouseCoopers LLP underscores a pressing issue not as widely discussed: the impact of climate change on future metal supplies. It reveals a daunting forecast where, even under an optimistic scenario for 2050, over half of the world’s copper mines could face significant to extreme drought risks, threatening the stable supply of this crucial wiring metal.
The repercussions of climate change on metal supplies extend beyond copper. Lithium and cobalt, essential for energy transition technologies, are under even greater threat, with 74% of their supplies exposed to drought risks. This vulnerability is not just theoretical; it has real-world implications. For instance, Zambia’s copper mines have already encountered power supply challenges due to drought-affected hydroelectric installations, and similar water shortages in Chile have constrained copper production for years. As the industry turns to alternative solutions like seawater, the escalating operational costs and complexities highlight the intricate relationship between mining practices and environmental sustainability.
Moreover, the concentration of global supplies in just a few countries adds another layer of risk. For copper, Chile, Peru, and China together produce more than half of the world’s supply, emphasizing the potential global ripple effects should climate change disrupt these critical sources. This geographical concentration, coupled with the escalating threat of climate change, presents a clear warning: the dependency on a handful of countries for materials essential to the clean-energy transition is a vulnerability that needs urgent attention. As the global climate leader at PwC UK, Emma Cox notes, the underappreciated dependencies and impacts a changing climate could have on metal supplies underscore the necessity for a broader understanding and action to mitigate these risks.
