Footnotes

Refer also to the Data Methodology section of the report for an explanation of some data sources and calculation methodologies.

a   Scope 3 emissions for FY14 are impacted by the lack of waste data for Hills M2 and LCT.

b   Scope 3 emissions for FY15 are impacted by the lack of waste data for Gateway, Logan, Go Between Bridge, Legacy Way, the 495 Express Lanes and 95 Express Lanes. We will attempt to report fully in FY16.

c   This excludes energy used for building elevators and for heating and cooling as our current lease agreements make it difficult to accurately measure our total building emissions.

d   Air emissions data reflect customer vehicle emissions from tunnel ventilation stacks. CLEM7 also has exhaust vent stacks, but there is no requirement to undertake air quality monitoring within the stacks. Air quality monitoring is completed on a local community scale to ensure no adverse effects, and so is not representative of the in-tunnel air quality.

e   This groundwater is natural leakage that drains into road tunnels. Most of this water is treated by water treatment plants and either returned to the aquifer or discharged to waterways.

f   This figure comprises potable water used to clean the filters at the water treatment plant and additional recharge to the aquifers as required.

g   Data on the number of spills and waste was not available for the Sustainability Report for our US assets (495 Express Lanes and 95 upgrade) and Queensland assets.

h   The figure for recycled waste for corporate offices include recycled paper, organic waste and commingled recyclables.

i   e-TAGs that are returned by customers and found to not be working are returned to our supplier for proper disposal. The tags are dismantled into their separate components and are recycled or disposed of as appropriate.
