2011 Sustainability Report

The 2011 Sustainability Report is Investa’s tenth published sustainability report, demonstrating Investa’s long track record of environmental performance. This report is shorter than previous reports, reflecting our commitment to focus on the key issues and environmental impacts of our business and to provide more effective and efficient reporting.
Throughout 2012, we plan to update performance statistics on our website to drive better performance in our business and to deliver transparency for our stakeholders. We invite you to explore our progress.

Management Statement

Since 2003 Investa has published ten annual sustainability reports, three concise reports and one ‘interim report’, the 2007 Sustainability Results Update, which bridged our transition from ‘financial year’ to ‘calendar year’ reporting.  This 2011 report is our fourth full calendar year report.
A full explanation of Investa’s approach to reporting data is detailed in our Reporting Rules, available below.

Independent Assurance

Investa has engaged KPMG to provide limited assurance on selected performance data for the year ended 30 September 2011. KPMG has 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.
KPMG’s assurance statement, includes the selected performance data and the relevant reporting criteria.

Reporting Rules

Each year we try to provide the most comprehensive and accurate reporting that we can. For consistency, and to aid understanding, we apply reporting rules to our data. We have two sets of rules:

• Volume Statistics Rules relate to our reporting of greenhouse gas emissions and mains water usage attributable to all businesses and facilities under Investa’s operational control.
• Intensity Statistics Rules relate to our reporting of energy, greenhouse emissions, water and waste statistics for Investa’s managed office portfolio and are summarised here in our Schedule of Assets and Reporting Status.
• Investa uses the National Australian Built Environment Rating System (NABERS) to rate and disclose the performance of office buildings each year. A full Schedule of 2012 NABERS Ratings is available here.
