Context, Scope And Methodology

The global energy transition and technological change are driving unprecedented demand for critical raw materials (CRM). For the European Union (EU), secure and affordable access to these materials is essential for climate, industrial, and digital objectives. CRM supply chains are complex and increasingly shaped by geopolitical competition. This report assesses digital traceability as a policy response, with a focus on producer-country perspectives and artisanal and small-scale mining (ASM). The methodology combined desk research with over 20 semi-structured interviews and a comparative mapping of 27 digital traceability systems. Findings were validated during a multi-stakeholder roundtable in February 2026.

ESG Standards And Traceability

Environmental, social, and governance (ESG) standards in the mining sector are rapidly evolving from voluntary schemes to mandatory requirements. Regulatory consolidation in the EU, including the Corporate Sustainability Due Diligence Directive (CS3D) and the Battery Regulation, is turning responsible sourcing into a binding obligation. Digital traceability is increasingly integrated into these frameworks to support the implementation of digital product passports (DPP). The report identifies four key dynamics driving convergence: regulatory consolidation, standard consolidation (such as the Consolidated Mining Standard Initiative), technical alignment, and digital integration through foundations like the UN Transparency Protocol (UNTP).

Traceability System Architecture

The report distinguishes four categories of traceability systems: commercial solutions, multi-stakeholder programmes, support infrastructure, and research and development (R&D) initiatives. These systems utilize different verification mechanisms, categorised as Proof of Intention (policy commitments), Proof of Transaction (chain-of-custody records), and Proof of Origin (scientific verification like isotopic analysis). Four chain-of-custody models define how materials are tracked: identity preservation, segregation, mass balance, and certificate trading. Mass balance has emerged as the dominant model for processing-intensive and battery-related minerals like lithium, nickel, and cobalt.

Comparative Mapping Of Digital Traceability Systems

The mapping of 27 systems reveals that commercial solutions are generally designed to operate across multiple minerals and sectors, with strong coverage midstream and downstream. In contrast, multi-stakeholder programmes like iTSCi or Better Mining tend to have a narrower mineral and geographic focus but extend traceability into early-stage production, including ASM. Support infrastructures, such as Catena-X, provide the technical foundations for other systems to communicate. R&D initiatives like BATTRACE and CIRPASS-2 focus on optimising solutions and testing DPP architectures aligned with the Ecodesign for Sustainable Products Regulation (ESPR).

Feasibility Assessment Of Traceability Approaches

Basic infrastructure remains a fundamental constraint, particularly in mining areas where gaps in connectivity and electricity are common. ASM faces structural challenges including informality and limited access to finance, necessitating pragmatic design that begins at aggregation points rather than the mine site. Interoperability is the key enabler for scale, requiring shared identifiers and exchange protocols to prevent system fragmentation. Financially, many downstream companies are reluctant to cover full implementation costs, leading to a structural dilemma where benefits accrue downstream while costs are incurred upstream.

Impact Assessment Of Advancing Traceability

Traceability can strengthen mineral governance and revenue mobilisation. In Indonesia, the SIMBARA platform has reportedly prevented illegal mining worth Rp 3.47 trillion and increased state revenue. In Tanzania, mineral markets have increased the ASM contribution to national revenue from 4% to 40%. However, high costs can exclude upstream actors and encourage illicit flows if they cannot recover expenses. Furthermore, blockchain-based systems can be energy-intensive; however, shifting from proof-of-work to proof-of-stake mechanisms can reduce energy consumption by an estimated 99%.

Recommendations For International Cooperation

International cooperation should treat traceability as a tool for due diligence, not a substitute, ensuring data is linked to risk mitigation. It is recommended to prioritise progressive improvement over absolute certainty and to promote interoperability through the alignment of identifiers. Cooperation should invest in capacity building for producer-country authorities and support country-specific roadmaps linking traceability to revenue mobilisation and industrial policy. Instruments like the Global Gateway should be leveraged to mobilise investment in energy and telecommunications infrastructure in ASM-intensive regions.

Conclusions

Traceability is becoming central to responsible CRM value chains, moving from a niche mechanism to a structural feature of supply chain governance. Technological advances make tracking feasible, but technology alone does not ensure responsible sourcing; its value depends on how information is used to guide decision-making. Long-term scalability requires reframing traceability as shared operational infrastructure rather than a discretionary compliance add-on. Realising its strategic potential depends on addressing structural constraints, managing fragmentation through interoperability, and ensuring the meaningful inclusion of the ASM sector.
