Environmental, Social and Governance Issues Associated With Sourcing Materials

Material Insights uses a proprietary approach to rate the importance of supply chain ESG issues for downstream users of materials based on information contained in publicly available reports.

Each material is assigned a score to measure the strength of association with different environmental, social, governance, or occupational health and safety issues. The material’s strength of association with each issue is categorised on a scale ranging from very low to very high, according to the severity and credibility of identified reports. 

This data can be used by downstream users to help identify issues that require further investigation, in accordance with the risk-based due diligence approach recommended by the OECD. The risk categories featured are aligned with RMI’s standards.

No data is displayed where no public issues reports are associated with the issue-material combination.

Money Laundering

Money laundering is the process by which criminals disguise the illegal origin of the proceeds of criminal conduct by making such proceeds appear to have derived from a legitimate source. Money laundering in the mineral supply chain occurs when minerals purchased using the proceeds of crime are then reintroduced into the market. It also occurs when minerals are used as an alternative currency in illicit transactions, such as purchases of weapons or drugs. Trade-based money laundering involves techniques like over- and under-invoicing, phantom shipping, and multiple invoicing.

Physical Instability, Soil Erosion and Land Degradation

Physical instability refers to the structural failure or movement of landforms and man-made structures, such as pit walls, tailings dams, waste rock dumps, or slopes, due to excavation, blasting, or natural forces. Soil erosion is the removal of topsoil by wind, water, or human activity, accelerated by the disturbance of land during exploration, excavation, and waste disposal. Land degradation is the long-term decline in the quality, productivity, and ecological function of land due to mining activities, such as deforestation, soil contamination, and habitat destruction.
