With more than 500 member companies, the Responsible Minerals Initiative (RMI) is one of the world’s largest industry associations focused on advancing responsible mineral sourcing across global supply chains. The RMI supports comprehensive due diligence ecosystem through leading standards for smelters, refiners and recyclers, data, and collaborative actions across minerals supply chains.
The RMI serves as a bridge between upstream and downstream companies, facilitating accountability and transparency through third-party assessments, facility data, and reporting on minerals due diligence.
The RMI's management systems approach is designed to validate conformance to standards for progressive due diligence, to help improve practices and support compliance with major regulatory frameworks worldwide.
The RMI does not validate minerals, material or mines. Founded in 2008 and an initiative of the Responsible Business Alliance (RBA), the RMI is experienced in helping companies build more responsible, resilient, and transparent mineral supply chains.
The RMI has launched its updated Theory of Change along with its first impact report for 2023.

What We Do
The Responsible Minerals Initiative (RMI) helps facilitate responsible mineral sourcing by equipping companies with internationally aligned standards, tools, data, and assurance programs that support due diligence across primary and secondary mineral supply chains. Rooted in the OECD Due Diligence Guidance and the UN Guiding Principles on Business and Human Rights, the RMI helps companies meet rising expectations under new regulatory due diligence laws.
Together with participating companies and cross‑sector partners, the RMI strives to drive industry alignment, strengthens accountability, and support continuous improvement across global mineral supply chains. The RMI convenes diverse stakeholders and acts as a central voice for responsible sourcing, to help tools, expectations, and practices evolve with regulatory and market needs.
Companies across sectors look to the RMI for:
- Standards and third-party assessments to assess smelters, refiners and recyclers
- A unified data platform, the Facility Database, that brings together RMI‑validated data and verified datasets from other standards, providing a consistently updated view of companies across mineral supply chains.
- Regulatory relevant reporting templates – learn about the CMRT, EMRT, AMRT
- Risk identification and prioritization tools – learn about Material Insight and the Global Risk Map
- Supplier training, technical assistance and capacity building – learn about the e-Learning academy
- Interoperability and cross‑recognition with peer systems – learn about the UNTP
- Industry action through the RMI’s dedicated working groups
