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

2 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.
