REPORTING & DISCLOSURE TRACKING OUR PROGRESS DOW | REPORTING & DISCLOSURE | 150 Dow Disclosures – GRI Content Index 307-1 Non-compliance with environmental laws and regulations Environmental proceedings are listed in Part I, Item 3 of the Dow Inc. Annual Report on Form 10-K ~ for the year ended December 31, 2021, filed with the SEC on February 4, 2022. GRI 308: Supplier Environmental Assessment 2016 308-103 Management Approach See also: GRI 103 Management Approach (General) Dow’s supply chain is vast and global, with more than 30,000 suppliers providing materials and services to Dow each year. As such, it is critical to ensure that our suppliers and, in turn, our suppliers’ suppliers, align to Dow’s ESG priorities and strategies. Dow selects and manages its suppliers based on a robust set of criteria, ranging from performance and economics to ESG factors. Engaging suppliers that prioritize environmental issues is critical for Dow. In the reporting year, suppliers were engaged on ESG factors through data collection, policies and guidelines like the Supplier Code of Conduct ( Supplier Code of Conduct| Public Policy | Corporate  ), which stipulates the requirements related to Respect the Environment, Protect Health and Safety, and Protect Communities During Transportation. In addition, some Dow procurement selection processes include additional environmental criteria related to a certain sector or commercial area. Beginning in 2022, ESG criteria will be used for all sourcing decisions. The management, objectives and requirements for our suppliers and supplier evaluation include an evolving set of specific actions: 1. Inspiring Dow’s procurement staff and suppliers to learn more about sustainability issues via various training opportunities, share best practices on how to integrate sustainability into their activities, and to continuously identify new innovations and collaboration opportunities. 2. Working with suppliers to collect ESG data on an annual basis via programs like CDP and Ecovadis. Results are then integrated into supplier relationship management frameworks and improvement action plans. 3. Recognizing that our chemical supply chain management is a collaborative topic, Dow will use the Together for Sustainability (TfS) and Ecovadis partnership to expand our audit program for suppliers associated with potential ESG risks. 4. Finally, we seek continuous improvement, by not only lowering our supply chain’s environmental impact, but also by identifying new innovations to advance a low-carbon, circular and fair economy. These improvements are tracked through our supplier ESG data collection program, as well as through our success stories based on individual supplier engagements. In addition, Dow is continually monitoring our supply chain for potential ESG risks, flagging materials, regions or individual suppliers that could represent a negative environmental impact. On a high level, Dow considers the management approach effective when our suppliers are not associated with environmental claims or legal action. Management Approach Components Description Commitments Dow aims to leverage our supply chain to improve ecological and social outcomes and contribute to the transition to a more sustainable economy. Targets As part of our WLO goal, Dow will demonstrate a 50% improvement in a Transportation Stewardship Index through progress in incident-free performance, leading-edge programs to influence logistics and raw material suppliers, and risk reduction across the value chain by 2025.
