Being Australia's largest retailer of energy means that measuring and managing our Greenhouse footprint is a significant part of our overall sustainability strategy and reporting.

In the energy industry, to get an accurate picture of a company’s greenhouse performance it is not enough to look solely at the total amount of greenhouse gas emitted from the company’s operations. It is equally important to examine the greenhouse intensity of the assets managed and invested in by the company, and how the company’s business strategy will contribute to the overall greenhouse intensity of Australia’s economy into the future.

We use three approaches or ‘footprints’ to measure and explain the annual greenhouse gas impact of our operations, our equity interests and the energy we supply to customers.

 

2007/08 (Mt CO2e)

2006/07 (Mt CO2e)6

Operational Footprint

Equity Footprint (Overseas)

Energy Supply Footprint

In this section we also describe the greenhouse performance of our portfolio of generation assets where we own or control the electricity dispatch using a measure of greenhouse intensity per unit of output.

The table shows the total annual greenhouse gas emissions for AGL Energy Limited. Data for 2006/07 includes those activities of The Australian Gas Light Company that formed part of the ongoing operations of AGL Energy Limited from 1 July 2006 to 25 October 20067.

For details of AGL’s reporting boundary and calculation methodology see Greenhouse and Energy Reporting Protocol.  Selected greenhouse and energy data presented in the report has been assured by ERM Australia Pty Ltd.  Details of the assurance are provided in the Greenhouse and Energy Reporting Protocol.

7 On 6 October 2006, The Australian Gas Light Company and Alinta Limited shareholders approved the merger of the Australian Gas Light Company's infrastructure and asset management businesses with Alinta and the subsequent separation of The Australian Gas Light Company's energy business to create AGL Energy Limited. The separation became effective and AGL Energy Limited commenced operations from 26 October 2006, although AGL Energy Limited commenced trading on the Australian Stock Exchange (ASX) on a deferred settlement basis from 12 October 2006.
