OECD Responsible Mineral Supply Chains: Practical Due Diligence Steps For Mining And Metals
Framework/Tool
This source outlines OECD’s risk-based five-step due diligence framework for responsible mineral supply chains, applicable to all minerals and company types.
- Explains why mineral supply chains matter to economies and the green transition, and the risks of human rights abuses and corruption.
- Sets a government-backed common standard for due diligence aligned with the OECD Guidelines for Multinational Enterprises.
- Describes the five steps: management systems, risk identification and prioritisation, risk management, third-party audits at choke points, and public reporting.
- Promotes progressive, good-faith, risk-based improvements rather than immediate perfection.
- Discourages blanket embargoes of high-risk areas, advocating leverage with suppliers to improve conditions.
- Highlights Annex II priority risks including severe human rights abuses, conflict financing, bribery, money laundering and non-payment of taxes.
