An important part of our annual sustainability reporting process is the independent assurance of sustainability performance data.
For FY17, we engaged Deloitte (AGL’s financial auditor) to undertake limited assurance of FY17 performance data in accordance with the Australian Standard on assurance engagements ASAE 3000 Assurance Engagements other than Audits or Reviews of Historical Financial Information (ASAE 3000).
The assurance covered three main elements:
- Assurance over the application of AA1000 principles in managing and reporting sustainability performance.
- Assurance over selected sustainability indicators, namely the performance against the FY17 sustainability targets, as well as selected greenhouse gas emission data and data relating to our material issues.
- Assurance over our self-declaration that the report has been prepared in accordance with the GRI Standards: Core option.
In practice, this involved Deloitte conducting interviews with management and employees responsible for managing processes and/or collecting data, testing processes, and reviewing data and calculations over a period of several months.
Deloitte concluded that ‘based on the procedures performed, nothing has come to our attention that causes us to believe that the Subject Matter has not been prepared and presented fairly, in all material aspects, in accordance with the Reporting Criteria’.
In addition to these elements, we have also engaged Deloitte to undertake limited assurance over the greenhouse gas emissions, energy consumption and energy production associated with AGL Loy Yang, AGL Torrens, Bayswater Power Station and Liddell Power Station, that will be included with of our Section 19 reports under the National Greenhouse and Energy Reporting Act. This process is underway and will be completed prior to the submission of our reports which are due to be submitted to the Clean Energy Regulator by the end of October.
