Critical raw materials: a concept that is less stable than it appears

Critical raw materials lists are expanding. The European Union's current list includes 34 materials, up from 14 in 2011. The United States now designates 60 critical minerals, up from 50 in 2022. Both jurisdictions are investing significant political capital in securing these materials through legislative frameworks, strategic project designations, equity stakes in producers, and, in some cases, the activation of emergency powers. The policy apparatus erected around critical minerals has never been larger or more consequential.
Yet the concept at the foundation of all this activity, criticality itself, is rarely examined by the communities that depend on it. Policymakers invoke critical materials lists as if they were objective inventories of geological scarcity. Investors reference them as signals of demand. Project developers treat designation as a gateway to public support. All of these uses are legitimate, but they rest on analytical foundations that are more complex, more variable, and less stable than they are generally understood to be.
Criticality is not an intrinsic property of a material. It is a relational judgement about the intersection of dependency and vulnerability, shaped by specific economic structures, policy priorities, and geopolitical conditions. Understanding how that judgement is made, where it varies, and why it changes is not an academic exercise. It has direct consequences for which materials attract policy attention, which projects access public financing, and which supply chains are prioritised for diversification.
The two-dimensional logic
Most criticality frameworks operate on two axes. The first is economic importance: how essential is a material to the sectors that drive an economy's output and strategic position? The second is supply risk: how vulnerable is the availability of that material to disruption from concentration, governance failure, trade restrictions, or structural supply inelasticity?
Materials that score highly on both dimensions are classified as critical. This two-dimensional logic has become the methodological standard across major jurisdictions, but it is applied with meaningful differences in granularity, scope, and institutional process.
The EU's methodology, formalised in the Critical Raw Materials Act, evaluates economic importance at the sectoral level, assessing each material's contribution to value added across strategic ecosystems including renewable energy, digital technologies, aerospace, defence, and health. Supply risk is quantified through concentration indices, import reliance, governance indicators in supplying countries, and the feasibility of substitution or recycling. The result is a framework that emphasises the EU's industrial and strategic priorities: decarbonisation, digitalisation, and technological sovereignty.
The US approach, administered through the US Geological Survey under the Department of the Interior, is similarly structured but reflects different institutional arrangements. The 2025 list, published in the Federal Register on 7 November 2025, was developed using an updated methodology that evaluates supply chain risk through an economic effects assessment modelling over 1,200 potential trade disruption scenarios across more than 400 industries. This represents a significant methodological advance over the approach used for the 2022 list and reflects the current Administration's framing of critical minerals as a national security priority, with the Department of Defense, the Department of Energy, and the Department of Agriculture each contributing additions through interagency review.
The underlying logic is consistent: map dependency against vulnerability. But the outputs differ, and they differ for reasons that illuminate what criticality actually measures.
Why the critical raw materials lists diverge
The EU designates 34 critical raw materials. The US designates 60 critical minerals. The overlap is substantial but incomplete, and the divergences are instructive.
Some differences are structural. The US lists individual rare earth elements separately (cerium, dysprosium, neodymium, and so on), while the EU groups them into heavy and light rare earth categories. This inflates the US count but reflects a genuine analytical choice: individual rare earths have different supply profiles, applications, and risk characteristics, and disaggregation allows more targeted policy intervention. Other differences reflect economic structure. The US includes materials such as potash, silver, and zinc, reflecting agricultural, industrial, and defence applications that are weighted differently in the American economy than in the European one. The EU includes feldspar, helium, and strontium, which do not appear on the US list.
More consequentially, the lists reflect different policy cycles and strategic priorities. The expansion of the US list from 50 to 60 materials in 2025 was driven in part by the Trump Administration's focus on minerals essential to energy production, defence, and artificial intelligence infrastructure. The addition of uranium, for instance, was prompted by Executive Order 14154, which directed the Secretary of the Interior to consider its inclusion. The EU's list expansion has been shaped by the energy transition and by supply chain vulnerabilities exposed during recent geopolitical shocks, including the addition of nickel, copper, and silicon metal in recognition of their growing importance in batteries, electricity networks, and semiconductors.
This divergence is not a deficiency. It is the natural consequence of a relational concept applied to different economic systems with different strategic priorities. But it does mean that a material's status as "critical" is not universal. It is jurisdiction-specific, context-dependent, and subject to revision.
For organisations operating across jurisdictions, this creates complexity: a material may be critical in one framework and not in another, with different implications for regulatory treatment, public support, and investment incentives.
Criticality is not permanent
The temporal dimension of criticality is equally significant. Materials enter and exit critical lists as demand patterns shift, as supply sources diversify or concentrate, and as substitution becomes technically viable or economically attractive.
The trajectory of lithium and cobalt illustrates the point. Neither material appeared on the earliest iterations of the EU's critical raw materials list, established in 2011. Their inclusion accelerated sharply after 2015 as electric vehicle deployment scaled and their role in battery chemistries became central to energy transition pathways. Today, both are firmly embedded in critical and strategic designations on both sides of the Atlantic. Their status reflects not a change in geological reality, the resources were always there, but a change in economic importance driven by technological adoption and industrial policy.
The reverse trajectory is also possible, though less commonly discussed. If a material becomes substitutable at scale, or if supply sources diversify sufficiently to reduce concentration risk, its criticality score may decline. This has not yet occurred for any material of major strategic significance, but the possibility disciplines the framework: criticality assessments are designed to be periodically reassessed precisely because the conditions they measure are not static.
The EU is required to review its list by May 2027 and every three years thereafter under the CRMA. The USGS is required to update the US list at least every two years under the Energy Act of 2020, as amended. These review cycles ensure that designations reflect current conditions, but they also introduce a degree of policy uncertainty for projects with development timelines measured in decades.
Critical versus strategic: a distinction that carries weight
The terms "critical" and "strategic" are frequently used interchangeably in public debate, but they are not synonymous, and the distinction between them has practical consequences.
Critical raw materials are identified through analytical assessment. The designation is descriptive: it maps where vulnerabilities exist. Strategic raw materials are a narrower subset that have been prioritised for explicit policy intervention. The designation is normative: it reflects a political judgement about where public resources should be allocated, where regulatory support is most warranted, and where geopolitical exposure is least acceptable.
In the EU, the CRMA identifies 17 strategic raw materials based on their centrality to green and digital transitions and projected demand growth. Strategic designation unlocks a specific set of policy instruments: streamlined permitting with binding timelines (27 months for extraction, 15 months for processing), eligibility for EU financing instruments, and coordination support through the European Critical Raw Materials Board. As of early 2026, 60 projects have been designated as strategic across two selection rounds.
In the US, the equivalent is less formally structured but no less consequential. The Administration has targeted 25 core critical minerals for 90% domestic or allied sourcing by 2030, backed by Defence Production Act authorities, direct equity stakes in producers (MP Materials, USA Rare Earth), and the Project Vault strategic stockpile. These instruments are available to projects that align with strategic priorities, regardless of whether they are formally designated through a statutory process.
For project developers and investors, the distinction matters directly. A material that is critical but not strategic may warrant attention in risk assessments, but will not unlock the same public support mechanisms. A material that achieves strategic designation in one jurisdiction but not another creates asymmetric incentives for project location and investment.
And because strategic priorities can shift more rapidly than underlying criticality assessments, driven by policy cycles, geopolitical developments, or technological change, the landscape of public support is itself a source of risk that must be factored into long-term project planning.
The demand trajectory and the supply constraint
Criticality assessments would be a purely academic exercise if supply could respond flexibly to demand. It cannot.
The International Energy Agency's Global Critical Minerals Outlook 2025 projects that demand for lithium will grow fivefold by 2040 under stated policies, while demand for graphite and nickel will double. Copper, already among the most widely used industrial metals, faces projected demand growth of approximately 30% by 2040, driven by electricity networks, electric vehicles, and renewable energy infrastructure. Under the IEA's Net Zero Emissions Scenario, the figures are steeper still: lithium demand increasing eightfold, copper demand rising by 50%.
Against these trajectories, the IEA identifies significant projected supply shortfalls for both copper and lithium by 2035, with the current mine project pipeline pointing to a potential 30% shortfall for copper and 40% for lithium relative to projected demand under stated policies. New projects require 10 to 15 years from exploration to production, and longer where permitting is complex or contested. The European Court of Auditors, in its Special Report 04/2026, noted that EU mining projects can take up to 20 years to become operational.
This mismatch between demand growth and supply inelasticity is what makes criticality strategically significant rather than merely descriptively useful. It is not enough to identify which materials are critical. The question that follows, and the one that the remainder of this series addresses, is why supply challenges persist despite growing recognition of the problem, and where interventions are most likely to succeed.
From materials to systems
Criticality assessment is the entry point for understanding critical raw materials, but it is not the destination. Knowing that a material is critical identifies a vulnerability. It does not explain why that vulnerability persists, what prevents its resolution, or where targeted action would be most effective.
Supply outcomes are determined not by the properties of individual materials but by how those materials move through value chains, how those value chains are shaped by policy and regulation, how geopolitical dependencies constrain options, how environmental and social requirements filter the project pipeline, and how financing conditions determine which projects ultimately advance. Each of these dimensions interacts with the others, and weakness or misalignment in any one area can prevent otherwise promising projects from progressing.
The next article in this series examines the first of these dimensions: the structure of critical raw materials value chains, from exploration through recycling, and where the most consequential bottlenecks emerge.
