Methodology
This information will most likely be found in a Responsible Minerals Sourcing Policy, Sustainability Report or Conflict Minerals Report.
If the company describes either the actions taken in case of identified risks (e.g. termination, continuation, suspension), or some kind of corrective action plan for supplier improvement, the answer will be 'Yes'.
If the company has a Modern Slavery statement that is also a place where you might find this information, but the details must be explicitly related to the minerals chain in order to receive a 'Yes'.
About
In 2020, the Organisation for Economic Cooperation and Development (OECD) launched a project to develop a methodology to evaluate the extent to which companies embrace the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas, including how they align with its core elements, the 5-Step framework and the Annex II Model Policy. This metric belongs to that methodology.The OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas (OECD Guidance) was developed to provide recommendations to help companies respect human rights and avoid contributing to conflict through their mineral purchasing decisions and practices. The OECD Guidance is for use by any company potentially sourcing minerals or metals from conflict-affected and high-risk areas.
