GHG and air emissions

Our tunnels account for approximately half of our greenhouse gas (GHG) emissions, making them our single highest source. This is due to the fact that they require constant ventilation and lighting to ensure they remain safe for our customers to use throughout the day.

Environmental Protection Agency regulations govern the air emissions that are permitted from our tunnel portals. We are committed to ensuring our tunnel operations comply with these regulations, and in FY14 we were fully compliant with air quality regulations.

With the acquisition of Translink Operations in April 2014, Transurban took on full operational control of CityLink, and Tollaust (a wholly owned subsidiary of Transurban) took control of Hills M2 and Lane Cove Tunnel road operations from Transfield Services. This meant that we also inherited all related energy consumption and emissions, which had potential implications for reporting under the National Greenhouse and Energy Reporting Scheme (NGER).

To better understand our reporting obligations we reviewed our current and forecast GHG emissions profile and confirmed our operational boundaries and scope of reporting in relation to NGER.

For FY14, Transurban did not trigger the corporate threshold and so was not required to submit a corporate report. However, we did submit an NGER facility report for our CityLink asset due to the acquisition of Translink Operations.

In FY15 and beyond, Transurban is likely to be required to submit an NGER corporate report as we are expected to exceed the corporate threshold due to the acquisition of Queensland Motorways and Cross City Tunnel. In preparation for this we will be undertaking further assessments internally to better understand our reporting scope and define the reporting process for NGER.
