OUR COMPANY OUR G OVERNANCE OUR PE OPLE OUR C OMMUNITIES THE E NVIRONMENT THE NUMBERS A ND SMALL PRINT Design for the Environment We know many of our customers care about making sustainable purchasing choices. We encourage our device suppliers to participate in the UL ECOLOGO Certification Program, a voluntary independent certification that covers materials use, energy consumption, repairability, end-of- life management, packaging, and more. Approximately 78% of our new wireless handset models were certified through UL ECOLOGO and EPEAT Certifications in 2021. Going forward, T-Mobile will extend the range of wireless devices that undergo ECOLOGO or equivalent certification to include tablets and wearables. 78% of our new wireless handset models certified through UL ECOLOGO and EPEAT T-Mobile is on the ECOLOGO Standard Technical Panel for UL 110 (the Standard for Sustainability for Mobile Phones) and was involved in developing the industry’s first-ever environmental standard for wireless devices. Collaborating for Progress in Sustainable Packaging Sustaina ble packaging is one way we show our love for our customers and our planet at the same time. We strive to reduce packaging waste that goes to landfill and not saddle our customers with plastic trays and inserts they cannot recycle. We are working to evolve our device and accessory pa ckaging and shipping materials to be sourced from more sustainable, recyclable materials. In coordination with CTIA, we developed sustainable pa ckaging guidelines that help minimize the impact and footprint of packaging. The guidelines encourage suppliers to: ■ Create packaging that has as little single-use plastic as possible ■ Avoid any constructions that prevent recycling, like metal wire ties ■ Clearly label packaging so consumers know their recycling options ■ Use paper fibers from reputable, certified sources ■ Consider alternative, less environmentally harmful printing processes, such as using water-or soy-based inks Pivet, the case brand with its proprietary Self-Cycle TM technology, was among the new sustainable products we introduced to our accessories portfolio in 2021. It’s a case option that delivers premium design and functionality while being 100% bioavailable to nature’s “decay agents” found in locations like landfills. Pivet is an example of new materials technology opening up more sustainable choices for customers. Product Lifecycle Management Continued 2021 CORPORATE RESPONSIBILITY REPORT 60
