Global Reporting Initiative (GRI) Index

The Global Reporting Initiative (GRI) provides a set of standards for measuring and communicating performance on environmental, social and corporate governance topics. AT&T has aligned its reporting to the GRI-recommended disclosures since 2008. 

Our fiscal year 2024 reporting is prepared in accordance with the GRI Standards. The index below provides AT&T’s information for universal GRI Standards and relevant topic-specific GRI Standards, in alignment with topics identified in AT&T’s most recent assessment

General Disclosures

GRI 2-5 External assurance

External assurance was not sought for this GRI report as a whole. AT&T uses an external third-party organization to assure select environmental data. For our 2024 reporting, ERM Certification & Verification Services Incorporated (ERM CVS) assured calculations of our Scope 1, 2 and 3 (select categories) greenhouse gas emissions, as well as select energy figures. Learn more in the Independent Accountant’s Report.

GRI 2-6 Activities, value chain and other business relationships

We are a leading provider of telecommunications and technology services globally.
 

We announced plans to lead the U.S. in commercial-scale open radio access network (Open RAN) deployment, in collaboration with Ericsson. Over five years, we will spend approximately $14 billion to help build a robust ecosystem of network infrastructure providers and suppliers, with an aim that 70% of our wireless network traffic will flow across open-capable platforms by late 2026.

 

To further support our work in this area, in February 2024, we were pleased to step up as a leader in a new industry consortium—the Acceleration of Compatibility and Commercialization for Open RAN Deployments Consortium (ACCoRD). ACCoRD has been awarded $42 million by the National Telecommunications and Information Administration to advance adoption of interoperable infrastructure in wireless networks. The funding will go toward helping ACCoRD identify new methods of assessing innovations and technologies not covered by current best practices.

Total fuel consumption within the organization from renewable sources, in joules or multiples, and including fuel types used: 513,941 GJ. Fuel Types: Ethanol, Bio-Diesel, Renewable Methanol

 

In joules, watt-hours or multiples, the total:

  • Electricity consumption: 45,485,759 GJ
  • Heating consumption: N/A
  • Cooling consumption: N/A
  • Steam consumption: 133,931 GJ
  • Note: Data includes purchased/consumed energy as well as non-fuel self-generated energy (owned solar). 

Energy sold (including electricity, heating, cooling and steam sold) is not applicable. AT&T’s large-scale renewable projects are settled in the energy marketplace and not factored into section 302-1.

 

Total energy consumption within the organization, in joules or multiples: 53 million GJ

 

Standards, methodologies, assumptions and/or calculation tools used: Consumption values are generally tracked using inventory management systems and/or other documented estimation methodology (e.g., fleet records, generator runtime, etc.).

 

Source of the conversion factors used: Conversion factors are based on published criteria such as U.S. Environmental Protection Agency's Thermal Energy Conversions Technical Reference to convert from native unit of measure (gallons or MMBtu) to MWh, and then from MWh to GJ (x * 3.600).

GRI 302-2 Energy consumption outside of the organization  

AT&T does not currently track this information and is working to build the infrastructure and quality controls needed to monitor this data going forward.  

GRI 302-3 Energy intensity

Energy intensity ratio for the organization: 91.04 MWh total energy / thousand subscribers

 

Organization-specific metric (the denominator) chosen to calculate the ratio: Thousand subscribers

 

Types of energy included in the intensity ratio; whether fuel, electricity, heating, cooling, steam or all: Electricity consumption in MWh

 

Whether the ratio uses energy consumption within the organization, outside of it or both: Within the organization

GRI 302-4 Reduction of energy consumption

Amount of reductions in energy consumption achieved as a direct result of conservation and efficiency initiatives, in joules or multiples: 2,671,499 GJ

 

Types of energy included in the reductions; whether fuel, electricity, heating, cooling, steam or all: Electrical energy

 

Basis for calculating reductions in energy consumption, such as base year or baseline, including the rationale for choosing it: Annual electrical energy savings from historical consumption as baselined for each individual energy efficiency or conservation project.

 

Standards, methodologies, assumptions and/or calculation tools used: Consumption values are generally tracked using inventory management systems and/or other documented estimation methodology (e.g., fleet records, generator runtime, etc.). All reporting is in line with the GHG Protocol and completed with the approach and methodologies applied in previous years, with updates as needed to ensure methodologies remain current.

GRI 302-5 Reductions in energy requirements of products and services   

AT&T does not track this data, but we expect our device manufacturers to align with best-in-class energy efficiency practices. This alignment includes analyzing the life cycle performance of their devices to estimate energy impacts, incorporating or further developing energy management features on their devices, and establishing energy efficiency goals. Since 2015, AT&T has worked with other companies and industry associations to improve the energy efficiency of internet modems, routers and other in-home equipment through the Small Network Equipment Voluntary Agreement. Under the voluntary agreement, the average weighted power of each category of new small network equipment relative to broadband speed delivered has decreased annually since 2015, achieving an 89% overall reduction in 2023.
