We continue to be one of the largest corporate purchasers of renewable energy in the United States. AT&T is currently ranked 6th on the Environmental Protection Agency’s Green Power Partnership Top Partner Rankings and ranked 4th in Tech and Telecom.

The energy production of our domestic renewable energy portfolio (both on- and off-site) is nearly 2.8 million MWh annually, with more than 4,000 MWh coming from on-site sources.1 Most of our renewable energy now comes from off-site solar and wind contracts currently in production, along with hydropower received through supply contracts. In 2022, our large-scale renewable energy projects delivered nearly 2.80 million renewable energy credits to help offset our greenhouse gas emissions.

TC-TL-220a.1 Description of policies and practices relating to behavioral advertising and customer privacy Our Privacy Policy explains how we use customer information and keep it safe. It also outlines the choices customers can make at any time about how their information is used.Consumers can access information on our approach to privacy and data use, along with links to privacy choices and security tips, through the AT&T Privacy Center and AT&T Mexico Comprehensive Privacy Notice. In addition, privacy policies for AT&T’s apps and services are accessible within the apps and on the services’ websites. Through these policies, consumers can learn about their choices for opting out of certain data collection and marketing programs, such as behavioral advertising. Our approach to transparency includes:
  • Policy Updates & Questions: When we update our privacy policies, we appropriately notify our consumers to provide them with resources to understand the changes made and explain the changes on notices available on our Privacy Center website. Consumers can also send questions or feedback on our privacy policies, either by emailing or writing us at AT&T Privacy Policy, Chief Privacy Office, 208 S. Akard St., Room 2100, Dallas, TX 75202.
  • Transparency Report: AT&T publishes a biannual Transparency Report in which we provide comprehensive information about legal demands to which we responded. It includes the number and types of demands, those that were partially or completely rejected, demands for location information, exigent requests, and international demands. Our commitment to the law and our privacy principles are reflected in our comprehensive, voluntary reporting of this information to the public.
  • Consumer Resources: We strive to help consumers learn how to maintain privacy, safety and security in an increasingly connected world. To further equip consumers with the tools to control their privacy choices, in 2022 we launched a new portal to make it easier for consumers to opt out of email marketing. We also featured the AT&T ActiveArmor mobile security app on our Privacy Center to help customers view all their privacy and security resources on one platform. This free app helps consumers customize their robocall protection, manage nuisance calls and create a personal blocklist. For more information, please visit our Network & Data Security issue brief.
In 2022, we expanded the privacy choices offered to customers and updated our Privacy Policy to align with several new state privacy laws. Specifically, we extended the ability to access or delete personal information or request that we not sell data. These options are available to all U.S. consumers, not solely in states where offering these privacy choices is required. In addition, we began offering all U.S. consumers the ability to submit a correction request, appeal a privacy decision we made in response to privacy requests and transfer their data by requesting an access report in a portable format. We also launched a new course for employees to educate them about the updated privacy choices available to customers and courses on multiple domestic privacy laws.For more information on AT&T’s data protection and security practices, please see our Privacy issue brief.

  • Percentage involving customers’ personally identifiable information
  • Number of customers affected
AT&T is not able to provide information on data security breaches, as it is confidential.While we work hard to protect and safeguard the privacy of consumer and employee information, like all companies, we occasionally confront attempts to gain unauthorized access to our customers’ or employees’ data. We have created an action plan to help us to respond swiftly to these situations:
  • Oversight: Our Corporate Compliance Office oversees periodic testing of our incident response plans in partnership with stakeholders such as the AT&T Chief Security Office.
  • Action: The AT&T Incident Response team follows a carefully designed governance structure and response process, investigating suspected breaches and evaluating their potential impact. If we determine that a data breach has occurred, we notify affected consumers and authorities as required by applicable law. We test the incident response process through tabletop exercises to identify improvements, and we work to remain informed about current laws and regulations impacting data privacy so our response process remains compliant.

TC-TL-230a.2 Description of approach to identifying and addressing data security risks, including use of third-party cybersecurity standards The AT&T Security Policy and Requirements (ASPR) serves as a guide and a reference point for conducting business in a secure environment and protecting AT&T information resources. ASPR is a comprehensive set of security control standards based, in part, on leading industry standards such as ISO/IEC 27001:2013. ASPR applies to all employees and contractors and establishes the minimum required safeguards to protect computing and networking assets, data and services.ASPR aligns with laws and standards such as the National Institute of Standards and Technology (NIST) Cybersecurity Framework and NIST 800-53, as well as the European Union’s General Data Protection Regulation, the Criminal Justice Information Services Security Policy, and the California Consumer Privacy Act.AT&T maintains 2 global ISO/IEC 27001:2013 certifications. The scope of these certifications covers the AT&T global IP infrastructure and certain customer-facing managed services. We have also achieved ISO 9001:2015 certification,2 which demonstrates and reinforces our belief that customer satisfaction and expectations are the most important factors in the work we do, and we undergo annual third-party audits, such as those for the Payment Card Industry Data Security Standard, the Sarbanes-Oxley Act and SSAE 18/ISAE 3402.For details on our managerial approach to security, please see our Network & Data Security issue brief.

Materials from take-back:
  • Reused or sold: 89%3
  • Recycled: 11%3

We require that all U.S. device recycling and salvage vendors maintain an R2 certification. R2 is a comprehensive global certification awarded to facilities that adhere to the R2 responsible electronics recycling standards, which cover areas such as worker health and safety, environmental protection, chain-of-custody reporting and data security.AT&T collaborates with peers though the Global System for Mobile Communications Association, which has working groups focused on consumer device and network equipment recycling. In 2022, we also engaged with Cellular Telecommunications & Internet Association working groups to refine the industry standard for used mobile device grading. The goal of this initiative is to scale device reuse through common tools, technology and terminology, ultimately supporting consumer confidence in used and refurbished devices.For more information, please visit our Product Life Cycle and Waste Management issue briefs.

TC-TL-550a.2 Discussion of systems to provide unimpeded service during service interruptions Our systems collect billions of service-assurance measurements across our wireline and wireless networks every hour and analyze this data in near-real time to help improve performance and deliver our best customer experience.The AT&T Business Continuity Management Program includes management disciplines, processes and techniques to support our employees and critical business operations in the event of a significant business disruption, with a focus on maintaining delivery of customer services, including during climate-related events.
