    Overview

    The purpose of this document is to provide an overview of the processes and activities AT&T used to develop the company’s 2018 greenhouse gas (GHG) emissions inventory. The following document provides specific detail on the scope, standards, methodologies and results of AT&T’s 2018 inventory efforts.

    1. PROTOCOL: AT&T used the fundamentals of The Greenhouse Gas Protocol, A Corporate Accounting and Reporting Standard, Revised Edition by the World Resources Institute (WRI) and World Business Council for Sustainable Development (WBCSD). In addition, the protocol outlined by the EPA Climate Leaders program, which is founded on WRI principles, was applied to select emission sources to determine emissions.

    2. ORGANIZATIONAL BOUNDARY: AT&T has chosen to utilize the Operational Control approach to consolidate GHG emissions. This approach includes any asset or facility in which AT&T has an operating interest in the inventory. For instance, we included both owned and leased assets in our real estate portfolio and mobile fleet in our inventory. We believe that omitting estimated emissions from leased assets would result in a materially incomplete measurement. AT&T chose to use this approach because it more accurately reflects all operations. However, because there are no uniform and mandatory standards for data acquisition and reporting at this point, it is important to note that AT&T’s emissions data cannot accurately be compared to other entities.

    3. EMISSION SOURCES: The following sources within AT&T’s operational footprint were included in the 2018 Inventory:

    • Scope 1 (Direct): o Diesel o Natural Gas o Renewable Natural Gas o Number 2 Fuel Oil o Propane o Ground Fleet, including fuels:

    ▪ Diesel ▪ Gasoline, Unleaded ▪ Liquefied Petroleum Gas (LPG) ▪ Natural Gas, Compressed (CNG)

    o Flight Operations o Engines (Stationary Generators), including fuels:

    ▪ Butane ▪ Diesel ▪ Ethylene ▪ Number 6 Fuel Oil ▪ Gasoline, Unleaded ▪ Kerosene ▪ Natural Gas ▪ Propane

    o Engines (Portable Generators), including fuels: ▪ Diesel ▪ Gasoline, Unleaded ▪ Kerosene ▪ Natural Gas ▪ Propane

    o Refrigerant

    • Scope 2 (Indirect): o Purchased Electric Power o Purchased Steam o Natural Gas (Consumed by Fuel Cells)

    • Scope 3 (Ancillary Indirect): o Business Air Travel o Business Rental Car Travel o Electricity Usage of Products (Set Top Boxes, Residential Gateways)

    4. GREENHOUSE GASES The AT&T 2018 inventory includes measures of carbon dioxide (CO2), nitrous oxide (N2O) methane (CH4) emissions, and hydrofluorocarbons (HFCs), and their carbon dioxide equivalents (CO2-e).

    5. EMISSION FACTORS: Consistent with prior inventories, AT&T has elected to utilize guidance from the EPA Climate Leaders for emissions calculations in preparing the 2018 GHG Inventory, along with published emission factors from the US Environmental Protection Agency (EPA, including the Mandatory Reporting Rule and Greenhouse Gas Sources & Sinks), the US Energy Information Administration (EIA), the International Energy Agency (IEA), and the Department for Environment, Food & Rural Affairs (DEFRA). The emission factors for each greenhouse gas (CO2, CH4, N2O, HFC) were taken from guidance documentation and multiplied by the respective global warming potential (GWP), as determined by the IPCC Fourth Assessment Report (AR4), to derive an emission factor in terms of carbon dioxide equivalents (CO2-e). Detailed references are listed in Appendix B.
