1 Verizon’s GHG emissions are reported in CO₂e and are substantially composed of CO₂.

Approved by the Science Based Targets initiative (SBTi). For the purposes of evaluating progress against this target, we calculate market-based scope 2 emissions, which account for our use of energy attribute certificates. A majority of such certificates were obtained through renewable energy purchase agreements (REPAs). In certain instances, we swapped RECs generated by the REPA projects (project RECs) for an equal number of other RECs (non-project RECs) or accepted non-project RECs in lieu of project RECs pursuant to the REPAs.

Scope 3 emissions are also independently assured. Relevant categories included are purchased goods and services, capital goods, fuel- and energy-related activities (not included in scopes 1 or 2), upstream transportation and distribution, waste generated in operations, business travel, employee commuting, downstream transportation and distribution, use of sold products and end-of-life treatment of sold products.

Progress against these targets is calculated based on the total renewable electricity generated on-site or obtained in the form of energy attribute certificates divided by the total electricity consumed. A majority of these energy attribute certificates were obtained through REPAs. In certain instances, we swapped RECs generated by the REPA projects (project RECs) for an equal number of other RECs (non-project RECs) or accepted non-project RECs in lieu of project RECs pursuant to the REPAs.

5 In 2023, Verizon made adjustments in the calculation of the 2019 scope 3 baseline to reflect the following subsequent developments: a) the acquisition of TracFone Wireless, Inc. in November 2021, b) the application of the environmentally-extended input-output (EEIO) emissions factors developed by The Carbon Trust to relevant categories and c) the calculation of well-to-tank emissions to relevant categories in alignment with the 2023 calculation methodology. These updates resulted in an increase of ~12% in the scope 3 base-year emissions from 16,954,198 MT CO₂e to 18,979,748 MT CO₂e. The impact of the acquisition of TracFone Wireless, Inc. on Verizon’s base-year scopes 1 and 2 emissions was determined to be de minimis and therefore the 2019 scopes 1 and 2 base year values have not been updated.
