Air emissions - carbon monoxide (CO)
There was an overall decrease in carbon monoxide emissions from AGL's major operations (AGL Loy Yang, Bayswater Power Station, and AGL Torrens) in FY25 compared to FY24. Carbon monoxide emissions are generally a result of incomplete combustion of coal in the boilers.
AGL Loy Yang carbon monoxide emissions decreased 26% in FY25, with a 10% decrease in lignite coal combustion. It should be noted that FY24 emissions were high compared to previous years, likely due to an unfavourable combustion environment.
Bayswater Power Station carbon monoxide emissions decreased 2% in FY25. The observed decrease in emissions directly aligns with the decrease in sub-bituminous coal combustion (down 3%).
AGL Torrens carbon monoxide emissions increased 40% in FY25. The observed increase in carbon monoxide emissions is attributable to the increase in pipeline natural gas combustion at AGL Torrens (up 40%).
FY25 data was updated in November 2025. A subset of data (comprising emissions associated with the combustion of black coal at Bayswater Power Station, black and brown coal as well as natural gas at AGL Loy Yang Power Station, and gas and fuel oil at AGL Torrens) was reported with the initial release of the FY25 Data Centre on August 13. |
For the purposes of this data set, AGL Torrens comprises the Torrens Island Power Station and the Barker Inlet Power Station. |
All figures have been rounded to the nearest kilogram. |
Air emissions data for AGL sites is publicly reported NPI data (see www.npi.gov.au). |
The emission factors used in AGL's NPI reports are sourced from relevant industry emission estimation technique manuals available on the NPI website. |
