Leadership About Vision How We Operate What We Create How We Collaborate Looking Ahead Data Index Environmental footprint 2.3 Fuels 5. In the 2022 reporting year, several updates to reporting were applied to the 2021 and later inventories Fuel consumption 5 (a) Data from life cycle assessments for our hardware and sold products were used to calculate our Scope 3 emissions. (b) 2021 Category 1, 2, 8, & 11 emissions were recalculated with higher quality data inputs to improve accuracy. (c) All Scope 3 categories were broken out individually to improve transparency and eliminate the previously reported “Other Applicable Categories” 2017 2018 2019 2020 2021 2022 (d) Emissions associated with 3rd party construction related energy usage were recategorized into Category 1 instead of Category 3 to better align with the GHG Protocol Scope 3 Category Boundaries Natural gas (therms) - - - - 6,153,856 7,539,592 (e) Emissions associated with overhead electricity load at leased data centers was recategorized into Category 8 Instead of Category 3 to better align with the GHG Protocol Scope 3 Category Boundaries Diesel — diesel fuel (gal) - - - - 363,082 1,376,871 (f) 2021 Category 6 emissions were recalculated to incorporate more accurate and transparent methodologies for applying sustainable aviation fuel Diesel — distillate fuel oil emissions reductions No.4 (gal) - - - - 842,460 724,151 (g) 2021 Total Fuel and Energy Consumption were recalculated to eliminate 3rd party construction-related fuel use outside of Meta’s Operational Control Gasoline (gal) - - - - 52,375 119,955 Propane (gal) - - - - 0 0 Renewable fuels Hydrotreated vegetable oil - - - - 0 0 (gal) 2.4 Data center operations and design Power usage effectiveness (PUE) 2017 2018 2019 2020 2021 2022 PUE (data center energy 1.10 1.11 1.11 1.10 1.09 1.08 efficiency) Sustainable design Green building standards for data centers and offices (% of sq ft covered by green building standards and/or EnMS) 2017 2018 2019 2020 2021 2022 Total - - - - 98% 99% Data centers (LEED Gold or - - - - 100% 100% above, or ISO 50001) Offices (LEED Gold or - - - - 97% 98% above, or ISO 50001) 2023 Meta Sustainability Report 52
