Our methodology
This report uses the Australian
Government’s Department of Climate
Change National Greenhouse Accounts
(NGA) Factors Workbook (June 2009) to
calculate Scope 1, 2 and 3 emissions from
the following sources:
• Electricity,
• Gas,
• Refrigerants,
• Fuel: petrol, diesel, LPG and ethanol
10 per cent.
The 2009 WRI Workbook CO 2
Mobile
(version 1.3) has been used to calculate
emissions from air travel. The 2003
Workbook was used to derive the medium
haul emissions factor.
Scope 1 incorporates fuel use in our
vehicle fleet, gas burned in our Office,
Industrial, Retail, Residential and
Retirement Living assets, gas from a
decommissioned coal seam gas plant,
refrigerant emissions, and fuel, grease
and oil used by our contractors.
Scope 2 covers base-building electricity
purchased for our Office, Industrial, Retail,
Residential and Retirement Living assets,
our corporate tenancies, and electricity
used by our contractors.
Scope 3 covers transmission and
production losses from purchased
electricity, gas and fuel for our assets
and contractors, and emissions from
employee travel (flights and car hire).
Our emissions boundary
All figures are Australian operations.
We report according to our ‘operational
control’ boundary under the National
Greenhouse and Energy Reporting Act
(NGERA). We report on the base-building
electricity and gas consumption and the
resulting greenhouse gas emissions from
the Office, Industrial, Retail, Residential
and Retirement Living assets for which
we have operational control. The GHG
emissions from our four largest office
tenancies were 1,621,578 kgs of CO 2
for
calendar year 2007. This figure has not
been included in the emissions totals.
Our tenancy consumption for FY10 has
been included. For those assets that do
not have 12 months of data, estimates are
provided for those missing months.
For our Residential assets we report
electricity and gas consumption for
our operations and emissions from
contractors working on projects under
our operational control. This includes
electricity, gas, fuel, oil and grease
consumption. Our emissions boundary
includes a decommissioned coal seam
gas mine. Annual emissions from this
site are estimated at 12.4 tCO 2
-e pa.
Greenhouse gas intensity
The most appropriate measure of
emissions intensity is on a per square
metre basis for the individual asset
classes. We use the same ‘operational
control’ boundary for our total figures.
The greenhouse gas emissions of our
office and retail business are divided by
the floor area of those assets.
