With the demand for raw materials increasing worldwide and value chains spreading across different countries, international approaches can contribute to making mineral extraction adhere to environmental standards. This research report addresses how Germany can contribute, through international governance, to reduce the environmental impacts of mining activities outside its territory. It provides a stocktake of existing governance approaches at the international level or with transboundary effect. It then develops specific policy options and recommendations for the German federal government to strengthen international governance for an environmentally sound supply of raw materials. The scope included the extraction of abiotic raw materials up to processing and smelting. In terms of impacts, it included social impacts where they are linked to the environment.
