Sony's stakeholders care about sustainability issues, including ethics and respect for human rights and the environment, when it comes to the sourcing of raw materials such as minerals and paper. Sony is working with its suppliers to address issues related to human rights, labor conditions, health and safety, and environmental protection at production sites, as well as in its procurement of raw materials.
In October 2017, Sony established the Sony Group Policy for Responsible Supply Chain of Minerals as part of the effort to realize the responsible supply chain of minerals.
In the policy, Sony Pledges that in order to avoid contributing to conflicts or serious human rights abuses through our sourcing practices, Sony identifies certain minerals which are sourced in conflict affected and high-risk areas and which are high-risk for Sony from corporate social responsibility viewpoints as the "High-Risk Minerals" , and sets the policy to refrain from purchasing any products, components or materials that contain High-Risk Minerals, knowing that such High-Risk Minerals are contributing to conflicts or serious human rights abuses in the chain of custody.
To help ensure compliance with its policy, Sony requires its suppliers to source minerals from smelters that have been determined not to be contributing to conflicts or serious human rights abuses.
Sony has designed an internal due diligence framework to determine the country of origin and chain of custody for any High-Risk minerals in its supply chain. This due diligence framework is designed to conform, in all material respects, with the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas. The policy is available on its CSR web site, link below.
Further information on four minerals (Tantalum, Tin, Gold, Tungsten) and cobalt which Sony has identified as High-Risk Minerals as of October 2017 is available at "Addressing the issue of Conflict Minerals" and "Responsible Procurement of Raw Materials for Environment and Human Rights".
