Greenhouse gas emissions, energy consumption and energy production data reported as part of the AGL Greenhouse Footprint have been prepared in line with AGL’s interpretation of the National Greenhouse and Energy Reporting Act 2007 and supporting regulations.
The data presented in the AGL Greenhouse Footprint has been prepared for the reporting period 1 July 2008 to 30 June 2009.
The estimation of greenhouse gas emissions presented in the Operational Footprint has been carried out in line with the National Greenhouse and Energy Reporting (Measurement) Determination 2008 published by the Commonwealth of Australia dated 25 June 2008 and related guidelines.
Greenhouse gas emissions are all expressed in tonnes of carbon dioxide equivalents (t CO2e).
The measurement of energy consumption and energy production presented in the Operational Footprint has been carried out in line with the National Greenhouse and Energy Reporting (Measurement) Determination 2008 published by the Commonwealth of Australia dated 25 June 2008 and related guidelines.
Energy consumption and energy production are all expressed in gigajoules (GJ).
Greenhouse gas emissions, energy consumption and energy production presented in the Operational Footprint have been reported for the corporate group of AGL Energy Limited (the parent company and its wholly owned Australian subsidiaries) as determined in line with the National Greenhouse and Energy Reporting Act 2007.
Greenhouse gas emissions, energy consumption and energy production in the Operational Footprint have been reported for facilities over which AGL has ‘operational control’, as defined in the National Greenhouse and Energy Reporting Act 2007, within the organisational boundaries.
Scope 3 greenhouse gas emissions have been presented separately from the Operational Footprint for 2009. Scope 3 greenhouse gas emissions have been treated separately as the reporting of this data is not required under the National Greenhouse and Energy Reporting Act 2007. Scope 3 emission sources from AGL’s activities include our purchase of fuel (mainly natural gas) and electricity use for our office based activities. Scope 3 emissions from sources such as office waste disposal and travel are negligible and have not been included.
The Equity Footprint sets out AGL’s share (by percentage investment level) of the emissions from our fully or partially owned entities. AGL sources data from equity partners, where available, otherwise specific assumptions are made which are described in the report. Operational Footprint data reported only includes scope 1 and scope 2 emissions.
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 Energy Supply Footprint estimates the greenhouse gas emissions associated with the consumption of electricity and gas by our customers. The model used to estimate the emissions has been developed by AGL over a number of years. During that time AGL has worked with George Wilkenfeld and Associates to review the model. Results for the 2008/09 Energy Supply Footprint model were reviewed internally by the Merchant Energy and Carbon and Sustainability teams.
