AGL operates Australia’s largest electricity generation portfolio, accounting for around 20% of the total generation capacity within the National Electricity Market (NEM). This scale makes it Australia’s largest producer of greenhouse gas emissions. In FY25, AGL’s operational emissions were 30.7 MtCO2e - around 7% of Australia’s total emissions. The vast majority of these emissions (95%) come from coal combustion at AGL's Bayswater and Loy Yang A power stations, which are set to retire in December 2033 & FY35 respectively. AGL is also Australia’s largest gas retailer and second largest electricity retailer.

ACCR has been engaging with AGL since 2019 on its climate risk management, decarbonisation strategy and governance of industry associations.
