BGR Certified Trading Chains
The German Institute for Geosciences and Natural Resources (BGR) developed the Certified Trading Chains (CTC) approach and has implemented it at the pilot scale in Rwanda and the DRC.
The CTC scheme is designed to certify responsible mining and trade of minerals, with a focus on tin, tungsten, tantalum and gold. The scheme is geared to addressing the specific challenges that are associated with artisanal mining, and emphasises feasibility and impact in an artisanal context. It focus on process rather than certifying the achievement of performance targets.
