See our Energy Management issue brief. 

Total fuel consumption within the organization from non-renewable sources, in joules or multiples, and including fuel types used: 6,750,666 gigajoules (GJ). Fuel Types: Natural Gas, Fuel Oil or Diesel, Propane/LNG, Gasoline, CNG, Methanol, Kerosene, Jet Fuel

Total fuel consumption within the organization from renewable sources, in joules or multiples, and including fuel types used: 483,454 GJ. Fuel Types: Ethanol, Bio-Diesel, Renewable Methanol

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

Electricity consumption: 46,604,664 GJ

Heating consumption: N/A

Cooling consumption: N/A

Steam consumption: 142,474 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: 53,982,522 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).

Energy consumption outside AT&T operations occurs across the value chain and includes, in part, energy associated with customer use of AT&T enabled products and services. For 2025, AT&T estimates energy consumption outside the organization from customer use to be approximately 9,003,600 GJ, which is a combination of use of sold products and downstream leased assets, such as gateways.

This product use estimate is based on modeled data and reflects mobility device energy consumption over their average life on the AT&T network as well as annual energy consumption from leased gateways per reporting guidance from the Greenhouse Gas Protocol.

Energy intensity ratio for the organization: 94.02 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

Amount of reductions in energy consumption achieved as a direct result of conservation and efficiency initiatives, in joules or multiples: 2,550,654 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.

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. 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 2024.
