Scope 3 emissions
AGL's Scope 3 emissions for FY25 have decreased from FY24 levels. The largest reduction was in Scope 3 emissions associated with the supply of electricity to customers, and was driven by a decrease in electricity sales volumes in NSW in FY25, and declining grid intensity. Scope 3 emissions from the end use of natural gas by customers also decreased slightly, due to reduced gas sales volumes to customers in FY25. Decreased emissions from the end use of coal sold to Loy Yang B Power Station was driven by reduced brown coal sales from Loy Yang Mine to Loy Yang B Power Station. Other Scope 3 emissions data for FY25 is not available at the time of publication and has been estimated.
Scope 3 emissions source | FY21 | FY22 | FY23 | FY24 | FY25 |
|---|---|---|---|---|---|
Supply of electricity to customers | 5.9 | 4.9 | 6.3 | 8.2 | 6.9 |
Supply of natural gas to customers | 2.1 | 2.1 | 1.8 | 1.4 | 1.3 |
End use of natural gas by customers | 6.9 | 7.0 | 6.1 | 4.7 | 4.4 |
End use of coal sold to Loy Yang B | 9.9 | 10.4 | 10.0 | 10.2 | 10.0 |
Other (emissions from staff travel, waste, investments etc.) | 0.4 | 0.7 | 0.6 | 1.3 | 0.6 |
Supply of electricity to customers includes emissions associated with the generation, transmission and distribution of electricity AGL purchases from the market to meet customer demand where AGL is short generation (calculated at a state level on an annual basis at the point of sale to customer), as well as upstream emissions associated with fuel purchased for electricity generation at AGL's operated power stations. |
For the calculation of Scope 3 emissions associated with the supply of electricity to customers, AGL's generation position relative to customer demand is determined at a state level, on an annual basis. This assumes that there is no interstate distribution of electricity generated by AGL and sold between states. An assumed loss factor is applied to AGL’s pool generation, to account for the difference between pool generation and sales to customers on the same basis. |
Emissions from generation for electricity produced by AGL and sold into energy markets is excluded from this footprint. |
Supply of natural gas to customers includes emissions associated with the production, transmission and distribution of natural gas sold. |
End use of natural gas by customers assumes all gas sold is combusted by customers. |
It is assumed that natural gas production, transmission and distribution, and end use occur in the state and financial year in which gas is sold. |
Electricity and gas sold to ActewAGL (for supply to ActewAGL customers) is included, as ActewAGL is a customer of AGL. |
Annual Scope 3 emissions are estimated. AGL continues to prioritise improvements in the underlying data and assumptions used to increase the accuracy of its Scope 3 calculations. Calculation method changes have been retrospectively applied, with historical data restated to align with the updated approach in FY25. |
Greenhouse gas emissions are rounded to the nearest 0.1 MtCO2e. |
