Natural Resources Management Using Natural Resources Responsibly T-Mobile is committed to being a responsible steward of the natural resources we use. Our Environmental Policy lays out our commitments to do our part to protect the planet we all share. We strive to conserve water use throughout our operations, follow responsible paper management practices and sustainable packaging guidelines, and increase the purchase of products designed and manufactured in an environmentally sustainable way. Plus, we take a highly collaborative approach to natural resource management and conservation efforts, working closely with suppliers and non-profits, as well as in alliance with other corporations, to ensure we are improving efficiencies and following best practices across our value chain. Supporting Suppliers Who Use Less T-Mobile’s Responsible Sourcing Guidelines help us select and support the suppliers who source materials the right way. Our suppliers are an important part of our business, and these guidelines outline our expectations and ensure everyone is aligned to the same responsible sourcing practices, including: ■ Maximizing their use of recycled fibers and using natural fiber efficiently ■ Minimizing use of paper-based records in their own operations ■ Following sustainable forest management practices including obtaining certifications from independent bodies like the Forest Stewardship Council wherever a particular risk of deforestation is identified ■ Respecting indigenous and local land rights ■ Demonstrating best practice in mill and printer performance ■ Showing improvements in water and energy efficiency ■ Not using conflict minerals For a detailed look, check out our full Responsible Sourcing Guidelines . Water We strive to conserve water across our operations and understand the key role it plays in global supply chains. As part of the Science Based Target Network (SBTN) Corporate Engagement Program, we collaborate with other organizations on developing methods and tools to set science- based targets for nature, including water use targets. Wood fiber Responsible wood fiber usage protects forests, so we work to manage the use of paper and paperboard packaging material across our operations. For example: Paperless billing for all customers unless they expressly ask for paper bills ■ Our Responsible Sourcing Guidelines ensure suppliers follow best practices in regard to forest stewardship, recycling, and indigenous land rights ■ Minerals We are concerned about the human rights abuses and risks associated with the extraction, transport, and trade of certain minerals in the Democratic Republic of the Congo (DRC) and adjoining countries. These trade minerals, referred to as “conflict minerals,” include columbite- tantalite (coltan), cassiterite, gold, wolframite, and their derivatives. Our Responsible Sourcing Guidelines outline our expectations that suppliers do not use conflict minerals, as well as guiding them where necessary in improving due diligence. 2021 CORPORATE RESPONSIBILITY REPORT OUR PEOPLE OUR GOVERNANCE OUR COMMUNITIES THE NUMBERS AND SMALL PRINT 61 OUR COMPANY THE ENVIRONMENT
