Sustainability Report 2023 50 Emission [GRI 305-1, 305-2, 305-3, 305-4]10 10 Scope 1, Scope 2 and Scope 3 Category 1 figures have been restated due to an improvement in the emission calculation methodology which better aligns fuel activity conversion factors with the United States Environmental Protection Agency default emission factors for organisational greenhouse gas reporting. 11 There was a misstatement noted in our 2021 and 2022 GHG calculations for BEK mine, which resulted an overstatement of approximately 17% and an understatement of approximately 25% for FY21 and FY22 respectively. These have been corrected in current year’s report. 2021 2022 2023 Singapore and Indonesia corporate offices Total GHG Emissions (metric tonnes CO2e) 76 122 208 Scope 1 - - - Scope 2 76 122 158 Scope 3 Category 3 (Fuel and energy-related activities) - - 50 Total man hours worked 1,217 2,772 4,344 Emission intensity (tCO2e/man-hour) 0.062 0.044 0.048 SDJ mine Total GHG Emissions (metric tonnes CO2e) 59,683 48,242 42,605 Scope 1 704 1,374 1,306 Scope 2 42 46 48 Total Scope 3 emissions 58,937 46,822 41,251 Scope 3 Category 1 (BUMA-SDJ) 58,937 46,822 41,076 Scope 3 Category 3 (Fuel and energy-related activities) - - 170 Scope 3 Category 5 (Waste generated in operations) - - 5 Total coal production volume (tonnes) 4,539,593 4,305,689 2,131,637 Emission intensity (tCO2e/tonne of coal produced) 0.013 0.011 0.020 TBR mine Total GHG Emissions (metric tonnes CO2e) 59,650 85,506 106,816 Scope 1 1,074 1,371 1,283 Scope 2 63 54 80 Total Scope 3 emissions 58,513 84,081 105,453 Scope 3 Category 1 (BUMA-TBR) 58,513 84,081 105,278 Scope 3 Category 3 (Fuel and energy-related activities) - - 170 Scope 3 Category 5 (Waste generated in operations) - - 5 Total coal production volume (tonnes) 6,333,106 5,900,191 6,038,090 Emission intensity (tCO2e/tonne of coal produced) 0.009 0.014 0.018 BEK mine11 Total GHG Emissions (metric tonnes CO2e) 6,336 10,242 13,688 Scope 1 6,326 10,232 12,235 Scope 2 10 10 12 Scope 3 Category 3 (Fuel and energy-related activities) - - 1,441 Total coal production volume (tonnes) 50,784 141,381 209,765 Emission intensity (tCO2e/tonne of coal produced) 0.125 0.072 0.065
