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 2025, Verizon recalculated the base year (2019) Scope 3 emissions to reflect the following calculation methodology updates aligned with the current year reporting:
Emissions Factors:  Integration of Watershed-developed CEDA EEIO factors (Category 1, 2, and 6) and updated electricity emission factors sourced from the International Energy Agency (IEA) (Category 3).
Structural Alignment: Categorical separation of Category 1 (Purchased Goods and Services) and Category 2 (Capital Goods).
Expanded Boundary: Inclusion of packaging materials within Category 12 (Endo-of-Life Treatment) and of upstream (well-to-tank) emissions from electricity during the product use-phase within Category 11 (Use of Sold Products).
As a result, the 2019 baseline was adjusted from 18,979,748 MTCO2e to 18,189,022 MTCO2e, a net reduction of approximately 4%.
