Use Less

Transurban is focused on minimising the social and environmental impacts of operating our roads, tunnels, offices and construction projects. In simple terms, that means we challenge ourselves to ‘use less’.

We work to maintain robust environmental management, minimise natural resource use and create resource efficiencies during the design, construction and operation of our roads.

During construction and operation, we engage the services of major contractors, which typically take on responsibility for day-to-day delivery of major works and sub-contracting subject to conditions set by Transurban. To ensure we minimise impacts, all major project delivery contracts establish clear requirements and expectations, including but not limited to:

  • Providing project management and sustainability plans including a Sustainability Management Plan, Construction Environmental Management Plan, Stakeholder Engagement Plan and various other Risk and Governance plans
  • Using the Infrastructure Sustainability Council of Australia’s (ISCA) IS rating tool and achieving an ‘Excellent’ rating for contracted Australian projects. Refer to the Procurement section for further detail on IS

In ensuring environmental air quality impacts are minimised and high levels of road safety are maintained, our assets use a large amount of energy, primarily through the consumption of electricity to operate tunnel ventilation and lighting systems. In FY16, we conducted detailed analysis of our energy consumption profile across all assets and identified a range of energy efficiency opportunities that will improve the operating efficiency of our assets and achieve our ‘10 in 10’ energy efficiency target – to reduce our energy consumption by 10 per cent by FY23 from a FY13 baseline.
