Reducing infrastructure waste The AT&T Global Connections and Supply Chain Investment Recovery group establishes practices that minimize the environmental impact of our internal waste and e-waste. This team works with R2-certified vendors to recover and recycle network infrastructure assets. Network materials such as copper wire, fiber-optic cable and central office equipment are dismantled, sorted and baled by commodity in preparation for sale or recycling. Scrap fiber-optic cable can be shredded and milled to become components of roofing materials or burned for resalable steam energy. In 2021, the Investment Recovery group handled more than 15.6 metric tons (MT) of domestic U.S. operational waste and kept more than 15.4 MT of these materials from land fills. 29 This equates to a 98.7% diversion rate, a slight increase from 97.6% in 2020. ENVIRONMENT WASTE MANAGEMENT Water is a shared resource that’s vital for environmental sustainability and economic prosperity. AT&T focuses on water efficiency to reduce costs and enhance our resilience, and to help preserve the availability of water in our communities. Water is a critical input for our operations. 53% of our domestic water consumption occurs at locations where most of the water usage helps maintain the controlled and cooled environment required by our communications network. 25 We track water use and savings opportunities at our facilities with the AT&T Water Scorecard. We consolidate or reduce building space, where feasible, which has reduced water consumption by 267 million gallons since 2013. Our efforts to improve energy efficiency (page 35), such as enhancements to cooling systems, also positively impact our water use. Water recycling efforts At Warner Bros. Studios 8 in Burbank, CA, we use recycled water for landscape irrigation and in select cooling towers. Since 2013, the Studios have reduced potable water consumption 42%, conserving 232.19 million gallons. We’ve incorporated smart irrigation and rainwater collection systems into the AT&T Discovery District housing our Dallas headquarters. Our headquarters building also has a water harvesting system that collects and filters condensate from our air conditioning systems, for landscape irrigation. In 2021, this harvesting system saved more than 664,000 gallons of water. These water savings efforts helped the AT&T Discovery District earn SITES Silver certification, which recognizes sustainable and resilient land development projects. AT&T is committed to reducing and responsibly handling the waste we produce from our operations and the products we sell. Our operations generate various types of waste – including general solid waste, e-waste, retired network infrastructure and office furnishings, and hazardous waste. Our approach to waste management involves reuse and recycling programs, as well as initiatives to reduce our overall waste footprint. In 2021, we collaborated with third-party waste vendors to expand our pilot IoT-enabled dumpster monitoring program. The program uses sensors to inform our waste vendors when dumpsters are full, eliminating pick-up of partial loads. By routing trucks to dumpsters only when necessary, we’re minimizing disposal costs and reducing hauling- related carbon emissions. Our 30x30 initiative Based upon learnings from our previous 100-facility zero waste program, in 2021 we set an expanded goal to reduce the amount of U.S. waste sent to landfill 30% by 2030 (2019 base year). This “30x30” initiative addresses our entire waste footprint across more than 3,000 sites and is anticipated to exceed the impact of our 100-facility effort by 104 times, based on weight. In 2021, our landfill footprint decreased 26.7% from our 2019 base year – achieving 89% of our “30x30” goal. Keeping consumer e-waste from landfill We believe all electronic devices should be reused, refurbished or recycled. We work to keep electronic materials out of landfill through reuse programs – including a free portal where customers can recycle old equipment. In 2021, we recovered more than 21 million devices including mobile phones, internet gateways and television set top boxes. 28 Read more: Water Management Issue Brief Water management Waste management SINCE 2007 >250M mobility and broadband devices and set top boxes refurbished or recycled 28 Read more: Waste Management Issue Brief • Product Life Cycle Issue Brief 26.7% 0 30% Progress: Reduce amount of U.S. waste sent to landfill 30% by 2030 30 Water intensity: gallons/$ thousand revenue 25 2017 2018 2019 2020 2021 19.74 19.02 16.63 15.59 15.87 Water intensity: gallons/individual subscriber 27 2017 2018 2019 2020 2021 13.81 12.69 14.12 11.75 11.80 Saving water through smart building management In 2021, AT&T expanded use of our Energy and Building Management Solution (EBMS) to support energy and water efficiency at 1,030 total facilities. Leveraging IoT and Big Data principles, our EBMS helps property managers ensure equipment is operating optimally, reducing mechanical cooling needs and associated water consumption. Through our work with HydroPoint , we remotely monitor our irrigation systems in real time. HydroPoint’s solutions allow us to retrofit legacy systems to reduce water consumption an average of 40%. We’ve installed HydroPoint solutions at 133 facilities since 2017 and in 2021, this solution helped us save 74 million gallons of water.
