Energy supply greenhouse gas footprint

Emissions associated with gas supply decreased due to a reduction in gas sales volumes.


  • The energy supply footprint estimates the life cycle greenhouse gas emissions associated with the electricity and natural gas supplied to small-market, commercial and wholesale customers by AGL Energy (and its wholly owned subsidiaries) during the period.

  • It is assumed that natural gas is combusted in the state and year in which it is sold.

  • Natural gas and electricity produced by AGL and sold into energy markets are excluded from this footprint (although all of AGL’s acquisitions of electricity and natural gas to supply its customers are included). Other goods and services supplied by AGL are not considered.

  • The greenhouse gas emissions associated with electricity generation, transmission and distribution have been restated for previous years to include wholesale electricity sales.

  • Sale of electricity and gas to ActewAGL (for supply to ActewAGL customers) is included as ActewAGL is a customer of AGL.

  • Estimates are calculated using emission factors and Australian greenhouse gas inventory data published by the Commonwealth Department of the Environment. FY19 emissions are calculated based on emission factors published in the National Greenhouse Accounts July 2018 as well as factors derived from the National Greenhouse Gas Inventory 2017, both of which are the most up to date factors available at the time of release.

  • FY16 emissions from gas transmission and distribution have been updated based on updated information available in the National Greenhouse Gas Inventory 2016.

  • This footprint estimates the total scope 3 emissions associated with the supply of gas and electricity to AGL's customers.

  • Greenhouse gas emissions are rounded to the nearest 0.1 MtCO2e.
