Total Scope 1, 2 and 3 GHG emissions decreased by 0.3% annually on a location-based reporting basis, and increased by 0.1% on a market-based basis. On a per FTE basis, emissions declined by 2.8% on a location-based basis and 2.4% on a market-based basis. The reduction in absolute terms was achieved despite a rise in our Scope 3 emissions due to an increase in business travel and commuting associated with increased headcount and higher client activity in 2024 versus 2023. The magnitude of supplier-related emissions underlines the need for a more targeted approach to addressing those emissions.
The slight reduction in our total Scope 1, 2 and 3 emissions, hides a 4% decline in our absolute location-based Scope 1 and 2 emissions. The reduction was due to the implementation of several meaningful initiatives over and above our 3-year environmental reduction plan. Examples in our Bahrain head office included changing building air conditioning settings to an economy mode for evenings and the weekend; introducing motion sensors linked to the A/C system to switch off air conditioning when meeting rooms are not in use. Other notable actions across our global operations are outlined in the following sub-sections. Importantly, we now have more granular emission reporting and detailed carbon emission factors, improving the validity and accuracy of the data.
