GHG emissions report follows an operational control approach and includes proportionate GHG emissions from McDermott joint ventures operations with equity share equal or above 15%.
[2] GHG emissions reporting is based on carbon dioxide-equivalent (CO2e), a standard unit for measuring carbon footprints. The conversion factors to calculate CO2e are primarily based on EPA, IEA, and DEFRA.
[3] Scope 1 emissions are direct emissions from sources that are owned or controlled by McDermott. Scope 2 emissions are indirect emissions from consumption of electricity, heat, cooling and steam.
[4] Historical 昀椀gures have been restated to re昀氀ect the divestment of the CB&I business, in line with McDermott’s GHG Recalculation Policy aligned with the GHG Protocol. This restatement results in reductions of approximately 17% in 2020, 10% in 2023, and 11% in 2024 for total Scope 1 and
Scope 2 emissions.
[5] For year 2025, direct biogenic emissions of CO2 from the combustion of biodiesel, which are not included in Scope 1 GHG emissions amount to 2,874 tCO2.
[6] Fugitive emissions are currently excluded from the inventory and remain under assessment; preliminary estimates indicate they represent
