Since 2003 Investa has published eight annual sustainability reports, two concise reports and one 'interim report', the 2007 Sustainability Results Update, which bridged our transition from 'financial year' to 'calendar year' reporting. This is our second full calendar year report.
A full explanation of our approach to reporting data is detailed in our Reporting Rules.
Investa have engaged KPMG to provide limited assurance on selected performance data for the year ended 30 September 2009. KPMG have provided assurance on the following data: Electricity - consumption intensity (kWh/m2), Gas - consumption intensity (MJ/m2), CO2-e (electricity and gas) (kg.CO2-e/m2), Water - consumption intensity (L/m2) and Net Lettable Area - floor area (NLA) of buildings in the dataset. KPMG's engagement is consistent with the scope of work performed in prior periods and has been conducted in accordance with the Australian Standard on Assurance Engagements ASAE3000.
