Notes:
Scope 1 greenhouse gas emissions are emissions released into the atmosphere as a direct result of activities in a facility. Scope 2 emissions (also referred to as indirect emissions) represent the emissions released outside of a facility to produce electricity imported into a facility and used. Under the National Greenhouse and Energy Reporting (NGER) Act 2007 we report annually on our energy use and Scope 1 and 2 emissions to the Clean Energy Regulator (CER). This report is available on request.
The increase in emissions during the 2018-19 reporting period coincided with the commissioning of the Northern Gas Pipeline.
The increase of emissions in 2020-21 is contributed to by the CER updating/increasing the emission factor of methane used for calculating fugitive emissions. There was also increased fuel gas throughput across the Eastern Gas Pipeline, Darling Downs Pipeline and Roma North facilities.
In 2021-22, there was increased fuel gas throughput across the Eastern Gas Pipeline and Darling Downs Pipeline.
In 2022-23, our overall emissions decreased by 30.9 per cent relative to the 2020-21 reporting period. This was contributed to by a change in formula for calculating the fugitive emissions in distribution networks by the Clean Energy Regulator.
In 2023-24, our overall emissions increased by 4.26 per cent relative to the 2022-23 reporting period. Moving to a method of calculating JGN’s emissions based on sampling and analysis of the gas we transport (Method 3), rather than using a method based on national averages (Method 1) for calculating emissions1 for JGN is the main contributor to this increase.
