The Equity Footprint sets out AGL’s share (by percentage investment level) of the emissions from our fully or partially owned entities. The Equity Footprint indicates to AGL Shareholders the greenhouse gas impacts associated with their investment.
AGL considers that the Equity Footprint broadly meets the requirements of the WBCSD/WRI Greenhouse Gas Protocol’s ‘Equity Share Approach’ to greenhouse accounting.
The Equity Footprint is split between Australian and Overseas interests as described below:
The Australian Equity Footprint includes the following interests:
AGL owns a 50% equity interest in the ActewAGL Retail partnership which includes the operation of the retail electricity, gas and water businesses of ActewAGL. Minimal greenhouse emissions result from office based activities for the ActewAGL partnership. Emissions during 2006/07 were presented in the AGL Sustainability Report 2007 for all ActewAGL operations. The 2006/07 emissions presented in this report have been recalculated to account for only the ActewAGL Retail Partnership.
AGL held a 50% equity interest in Elgas, an LPG retailer, during part of the reporting period. AGL sold its interest in Elgas on 2 October 2008. AGL has estimated the greenhouse gas emissions associated with the Elgas activities for the period based upon 2007/08 operations data.
Loy Yang Power produced approximately 18.4 MtCO2e emissions in 20081. AGL has estimated greenhouse gas emissions for the reporting period using National Electricity Market data for the period multiplied by the published 2008 greenhouse gas emissions intensity. The greenhouse gas intensity of the electricity produced by Loy Yang Power in the 2008 calendar year was 1.209 kg CO2e/kWh2, which is lower that the Victoria electricity market average.
The Moranbah Gas Project is a joint venture between AGL and Arrow Energy, which produces coal seam gas from the Bowen Basin in Queensland to supply gas to the Queensland market including the AGL-owned 12 MW Moranbah Power Station. Greenhouse gas emissions are generated mainly from the coal seam gas combusted in the processing and compression of gas prior to sale and from gas fired electricity generation used by the project. AGL has estimated emissions for the reporting period using historical emissions data for 2007/08 published by Arrow Energy.
Queensland Gas Company Limited is a coal seam gas producer in the Surat Basin, Queensland. Emissions result mainly from the coal seam gas fuel combusted in the processing and compression of gas prior to sale.
On 20 January 2009, AGL acquired a 37.5% interest from Innamincka Petroleum Limited (INP) in activities carried out within permits PEL 101 and PEL 103 in the Cooper Basin. The activities include oil and gas production activities, and exploration of coal seam gas resources. AGL has estimated the greenhouse gas emissions from these activities based on data provided by Innamincka Petroleum.
AGL holds a 50% interest in Energy Infrastructure Management which over the period operated a range of gas infrastructure assts including the North Queensland Gas pipeline and the Berwyndale to Wallumbilla Pipeline. Greenhouse gas emissions result from fugitive emissions along these pipelines and fuel use in the course of operating the pipelines.
During the reporting period AGL also had equity interests in the CSM Energy, Central Queensland Energy Joint Venture, Mascotte Joint Venture, Tristar Petroleum, and the Hunter Gas Project (prior to the acquisition of the project by AGL on April 1, 2009). AGL estimates that the greenhouse gas emissions associated with the activities carried out as part of these projects are considered negligible within the AGL Equity Footprint.
The Overseas Equity Footprint for 2008/09 comprises AGL’s upstream gas interests in Papua New Guinea. On 18 December 2008 AGL completed the divestment of its joint venture interests in two oil field production development licences (11.9 per cent and 66.7 per cent) located in the Southern Highlands of Papua New Guinea. AGL is no longer involved in these activities and therefore an estimate has been made of greenhouse gas emissions from the previous year’s operations data.
