Critical Minerals and Sustainable Energy Transition

The shift from fossil‐based energy systems to low‐carbon technologies relies heavily on a suite of minerals deemed critical for their unique properties and inelastic supply. Lithium, cobalt, nickel, rare earth elements and platinum group metals underpin batteries, electric drivetrains, wind turbines and solar photovoltaics. Rapid expansion of renewable power and electric mobility has triggered unprecedented growth in demand, exposing vulnerabilities in supply chains, environmental stewardship and social licence to operate. Sustaining this transition requires not only scaling up mining capacity but also minimising ecological disturbance, securing ethical sourcing practices and mitigating geopolitical concentration risks. Circular economy approaches—encompassing reuse, remanufacturing and recycling—are increasingly viewed as essential to temper raw‐material extraction, reduce energy intensities and close resource loops. Life‐cycle assessment tools and system‐level optimisation models now integrate material flows to quantify environmental impacts, resource bottlenecks and the trade-offs inherent in achieving net‐zero targets. A holistic nexus of technology innovation, policy frameworks and investment in secondary resource infrastructure is vital to ensure that critical mineral supply aligns with sustainable energy ambitions.

Research from Nature Portfolio

Recent studies have quantified the trade-off between road transport decarbonisation and surging demand for lithium, nickel, cobalt and manganese under a range of electric-vehicle penetration scenarios to 2050. Projections indicate that, while high EV uptake can reduce greenhouse-gas emissions from fuel use almost to net zero by mid-century, it can also drive material demands by factors of up to 30 in some metals, highlighting tensions between climate benefits and mineral footprints.

Other work has mapped the spatial intersection of mining for energy-transition metals with biodiversity conservation areas, revealing that the vast majority of new mine developments for renewable technologies overlap with protected habitats or remaining wilderness. This analysis underscores the urgency of strategic mine planning and robust environmental safeguards to prevent biodiversity losses even as global emissions targets are pursued.

Technical terms

Critical minerals: Metals and rare elements essential for clean‐energy technologies whose supply is vulnerable to economic, geopolitical or environmental risks.

Circular economy: An economic system aimed at minimising waste and maximising the reuse, remanufacture and recycling of materials to close resource loops.

Total Material Requirement (TMR): A metric quantifying all material inputs—including hidden flows such as mine waste—needed to produce a given technology or service.

Life-cycle assessment (LCA): A systematic method to evaluate environmental impacts associated with all stages of a product’s life, from raw‐material extraction to end-of-life disposal or recycling.
