Best Buy Fiscal Year 2022 ESG Report | 69 Responsible sourcing . Chemicals. A healthy and safe working condition is a salient human right. Chemicals, while necessary as part of many manufacturing processes, directly impact the health of the people who make our products. To this end, we have adopted a Manufacturing Restricted Substance List (MRSL) to build a supply chain without hazardous substances. We continue to engage and work closely with industrial initiatives, NGOs and multi-stakeholder workgroups on methodology exploration. For example, through our participation in RBA’s Chemical Management Workgroup, we have access to some of the tools and guidance being developed by the Clean Electronics Production Network (CEPN). We have adopted the CEPN’s Process Chemical Data Collection (PCDC) template and have surveyed all our suppliers using this tool. We shared results from key suppliers with RBA so that they, along with the CEPN, can begin to assess the landscape of processing chemicals across the electronics industry. This transparency directly contributed to the development of a prioritized list of chemicals targeted for substitutions for the electronics industry. Our suppliers also play a key role in chemical management. We work closely with our suppliers on MRSL chemical identification, management, and minimization of risk. In FY22, we leveraged the updated PCDC and Qualitative Exposure Assessment Tool (QEA Tool) into our chemical management program. All in-scope suppliers are educated on the QEA Tool, and through that training, expectations related to chemical management programs are set.

We have established a regular reporting mechanism to require our suppliers to report their latest status on MRSL management and removal plan annually. We will continue to work closely with our suppliers to control the risk of the hazardous substances by removal, replacement, or other actions in the coming years.
