The Growing Role of Minerals and Metals for a Low Carbon Future

Core Content

This report by the World Bank explores the role of minerals and metals in achieving a low carbon future, focusing on the implications of climate change mitigation strategies on the demand for key metals and the opportunities for resource-rich developing countries.

Main Viewpoints

• Minerals and metals are essential for clean energy technologies, including wind, solar, and energy storage batteries.
• The demand for certain metals is expected to increase significantly due to the deployment of low carbon technologies.
• The transition to a low carbon economy will require a systemic and integrated approach to ensure sustainable mineral resource development.
• Developing countries with rich mineral resources will play a critical role in supplying the materials needed for the global clean energy transition.

Key Information

Metal Demand Trends

• The demand for metals such as aluminum, cobalt, copper, iron ore, lead, lithium, nickel, manganese, platinum group metals (PGMs), rare earth metals, silver, steel, titanium, and zinc is expected to rise.
• These metals are crucial for the manufacturing of clean technologies like wind turbines, solar panels, and energy storage systems.
• Renewable energy generation is projected to increase from 14% to 44% of the global energy mix under different climate scenarios, significantly increasing the demand for associated metals.

Climate Scenarios

• The study is based on three global warming scenarios: 2°C (2DS), 4°C (4DS), and 6°C (6DS).
• Under the 2DS scenario, the demand for relevant metals—especially for electric storage batteries—is expected to increase by over 1000% compared to the 4DS scenario.
• Wind and solar technologies are key drivers of metal demand, with aluminum, copper, and rare earth metals being particularly important.

Resource-Rich Developing Countries

• Latin America (Chile, Brazil, Peru, Argentina, and potentially Bolivia) has a strategic advantage in supplying copper, iron ore, silver, lithium, aluminum, nickel, manganese, and zinc.
• Africa (particularly Guinea) has significant reserves in platinum, manganese, bauxite, and chromium.
• Asia is dominated by China, which holds a large share of both base metals and rare earth metals.
• India is a major producer of iron and steel and titanium, while Indonesia, Malaysia, and the Philippines have opportunities in bauxite and nickel and cobalt to a lesser extent.
• New Caledonia has substantial nickel reserves.

Research Gaps and Recommendations

• There are significant gaps in data and mineral mapping, especially in Africa, Latin America, and Asia.

• Geographical anomalies exist between production and reserves for key metals, such as bauxite, where developing countries (excluding China) represent 30% of global production but 63% of global reserves.

• The report recommends further research and policy development in the following areas:

  • Policy-related inquiries:

    • Implications for future environmental and material impact performance.
    • Mapping minerals in developing countries.
    • Predicting technology choice based on supply constraints and demand patterns.
    • Developing networks and raising awareness among research and social communities.

  • Technology-related inquiries:

    • Electrical cabling and high-efficiency electric motors.
    • Lightweighting of vehicles.
    • Energy-efficient technologies and buildings.
    • Transmission and distribution.
    • Metal intensity of traditional and next-generation fossil fuel plants and nuclear facilities.
    • Metal supply and metal families.
    • Recycling rates and their impact on future metal availability.

Conclusion

The report highlights the critical role of minerals and metals in the transition to a low carbon future and calls for a coherent dialogue between the mining and metals industry, the climate change and clean energy communities, and developing countries. It emphasizes the need for sustainable and efficient resource management, policy alignment, and investment in mineral mapping and technology development to support the global shift to a low carbon economy.

Summary of Key Findings

• A low carbon future requires a significant increase in the demand for specific metals.
• Wind, solar, and energy storage technologies are the main drivers of this demand.
• China dominates the global supply of metals needed for low carbon technologies.
• Developing countries have a strategic role in supplying these materials.
• Data gaps and anomalies exist in the mapping of mineral resources.
• Recycling and technology choice are important factors in determining future metal demand.
• Integrated and sustainable approaches are needed to align mineral resource development with climate goals and broader sustainable development priorities.
