Notes:
Scope 1 greenhouse gas emissions are those released to the atmosphere as a direct result of an activity or series of activities at a facility. Scope 2 greenhouse gas emissions are those released to the atmosphere from the indirect consumption of an energy commodity (for example, from the use of electricity produced by burning coal in another facility. 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. This report is available on request.
The significant increase in emissions during the 2018-19 reporting period coincided with the commissioning of the Northern Gas Pipeline. In 2020-21, the Clean Energy Regulator increased the emissions 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 is due to a change in formula for calculating the fugitive emissions in distribution network by the Clean Energy Regulator.
