A new study published in Mineral Economics warns that meeting global climate targets will require roughly $2.1 trillion in mining investments between 2024 and 2050. The research, which draws on data from the UN Environment Program, the IEA, and BloombergNEF, projects massive demand increases for key minerals including a 794% rise for natural graphite and a 339% increase for lithium under a net-zero pathway. The paper highlights a major gap between climate ambitions and the financial reality of expanding mineral production. Exploration investment has declined from previous peaks, with historical returns averaging only $0.64 per dollar invested from 2011 to 2022. Higher sovereign bond yields are also raising the cost of capital, delaying mining projects. The authors argue that stronger sustainability standards could increase operating costs by 25% to 75%, and that market mechanisms must recognize these costs to reward responsible producers. To reduce pressure on primary extraction, the study points to circular economy strategies including reprocessing industrial tailings, recovering materials from end-of-life solar panels and wind turbines, and implementing digital product passports. The researchers emphasize that recycling alone cannot replace mining but can improve supply chain resilience while supporting global decarbonization goals.
