^{7 Based on an operational control approach, as defined by WRI GHG Protocol and scope guidance. Boundaries include all material operating locations.} 

^{8 Where actual consumption data was not available, we used a sampling approach or public information, such as equipment fuel efficiency and power ratings, to estimate fuel and energy consumption.} 

^{9 The 2021 methodology for capturing emissions associated with HVAC systems at our tower sites leveraged a unit type approach for each HVAC unit category (e.g., central air, window unit, etc.) to precisely reflect the differing energy consumption levels of each type and resulting emissions.}   

^{10 Based on actual consumption data for offices, owned and leased square footage, and estimates derived from nationwide energy intensity statistics from the Energy Information Administration’s (EIA) Commercial Building Energy Consumption (CBEC) Survey for the remainder of the offices.} 

^{11 Based on estimated allocation between diesel and gasoline vehicles.} 

^{12 Based on an operational control approach, as defined by WRI GHG Protocol and scope guidance. Boundaries include all material operating locations.} 

^{13 We used emission factors from 40 CFR Part 98 Tables C-1 and C-2 and EPA eGRID factors. Global Warming Potential documented in the Intergovernmental Panel on Climate Change AR5 report was used to calculate CO₂e for methane (CH₄) and nitrous oxide (N₂O).} 

^{14 Calculated using WRI GHG Protocol’s location-based method.}
