APPENDICES

ELECTRICITY, GAS AND WATER CONSUMPTION

Investa has reported on consumption of:

• Base building electricity, excluding tenant consumption
• All flows through a building’s main gas meter
• All flows through a building’s main water meter

In general, exclusions from our environmental indicators reporting are:

• Industrial buildings
• Jointly owned buildings (note: Buildings that are owned by external funds managed by Investa are not considered jointly owned.)
• Buildings that are solely car parks
• Buildings controlled by others, i.e. where the lease has transferred management control to the tenant (with the exception of 414 La Trobe Street Melbourne which is included in the water data).

EXCLUSIONS FROM ELECTRICITY, GAS, AND WASTE REPORTING

Specifically, the following buildings have been excluded for the nominated resource flow:

Electricity

• Buildings where base-building data has had to be apportioned from a single meter (metering base and tenancy electricity consumption), due to potential calculation inaccuracies

Gas

• Where a full year’s baseline data was not available

Waste

• Where waste statistics are not recorded; or the tenant manages the waste recycling program

GREENHOUSE GAS EMISSIONS

Investa calculates greenhouse gas emissions (CO₂-e) attributable to its operations by applying the Australian Greenhouse Office (AGO) pool coefficients for all electricity and gas reported using the definitions provided. Refer to the AGO website.

Greenhouse gas emissions offset or abated by making purchases under a recognised scheme such as Green Power^TM and Greenhouse Friendly^TM are stated as per the contract documentation.

Investa believes that emissions from electricity and gas consumed in operating the commercial office portfolio represent the majority of the company’s contribution to climate change under its direct control. Therefore, we have excluded emissions data from:

• Diesel used to power standby generation
• Travel and supply chain activities

REPORTING PERIOD

The reporting period for data drawn from third-party bills (energy, water and waste) is 1 April – 31 March.
