Recent Projects

RCS Global is one of the first companies to conduct conflict minerals validation audits of downstream suppliers in Asia. We verify suppliers’ responses in the CFSI Conflict Minerals Reporting Template and assess the level of conformance with the OECD Due Diligence Guidance.

RCS Global is the first RJC auditing body to conduct a verification assessment of an RJC Member with artisanal mining operations. Minera Yanaquihua S.A.C. in Peru was featured in the first RJC Impact Report as a successful example of ASM formalisation.

For Trafigura, RCS Global conducted upstream risk assessments of tin supply chains in high-risk areas in the DRC and Rwanda against the company’s Conflict Minerals Due Diligence Policy, and in line with the OECD Due Diligence Guidance.
