The OECD’s "Due Diligence Essentials" (2026) provides a mechanical framework for identifying and mitigating environmental, social, and governance (ESG) risks across global mineral value chains. As the energy transition drives a surge in demand for critical minerals, the report highlights that the average lead time from discovery to production has reached 18 years, intensifying pressures that lead to illicit trade and human rights abuses.
The sector is characterized by high geographic concentration and a diverse actor landscape, ranging from 45 million artisanal and small-scale miners (ASM) to massive capital-intensive multinationals. Core risks identified include mercury pollution (ASM gold mining generates 37% of global totals), child labor involving over 1 million children, and 7% of global greenhouse gas emissions. To address these, the OECD mandates risk-based due diligence that prioritizes traceability technologies and standardized data-sharing protocols to ensure supply chain integrity.
Key Pillars of the Responsible Minerals Framework
Lifecycle Risk Management: Implementing due diligence across all phases, from exploration (up to 10 years) and development (2-5 years) to extraction and mine closure.
Traceability Technology Integration: Scaling digital systems to track mineral origin, evolution, and ownership while embedding ESG data to prevent the entry of conflict minerals.
Mitigation of Hazardous Labor: Addressing the high accident rates in coal and ASM sectors, with a specific focus on eradicating forced labor and child labor in illegal operations.
Environmental Impact Controls: Combating deforestation (affecting one-third of global forests) and water contamination from tailings and acid mine drainage.
Governance and Anti-Corruption: Targeting "grand corruption" in licensing and contract negotiations, alongside "petty corruption" and extortion facing smaller artisanal miners.
Gender-Responsive Due Diligence: Developing safety and participation protocols for women, who currently make up only 15% of the formal workforce but face disproportionate risks of gender-based violence.
What is "Risk-Based Due Diligence"? Risk-based due diligence is an ongoing, proactive process where companies identify, prevent, and account for how they address actual and potential adverse impacts in their supply chains. It provides the mechanical framework to move beyond superficial "box-ticking" by requiring companies to engage with suppliers and use their leverage to influence upstream conduct. By following OECD standards, firms avoid "blanket avoidance" of high-risk areas, which can undermine local livelihoods, and instead focus on institutionalized improvement of labor and environmental standards.
Policy Relevance: Supply Chain Resilience & India's Strategic Mention
Operationalizing Resource Security: The report notes India's role as a major destination for minerals like African gold, accounting for a significant portion of declared imports in 2022.
Bypassing the 18-Year Lead Time: India’s RailTech Policy and Industrial Corridors act as domestic mechanisms to streamline the movement and processing of imported critical minerals, offsetting global supply delays.
Mechanical Link to Health Safety: The findings on radiation dose variations in cardiac imaging (IAEA 2026) highlight the "human capital" risk if mineral-dependent medical technologies are not managed with standardized safety protocols.
Sovereign Traceability Standards: India is positioned to lead South-South trade partnerships (GSTP) by adopting the OECD's phased approach to deploying mineral traceability mechanisms.
