Sustainability targets and data
In 2017 we set greenhouse gas emission reduction targets to achieve by 2030 and were the first top-20 ASX-listed company to have our targets validated by the Science Based Targets Initiative (SBTi). Then in 2020 we committed to achieving net zero by 2050. Our 2050 net-zero target (Scope 1, 2 and 3) is currently with SBTi for validation.

Data below shows how we are tracking towards our emissions targets and how we are decarbonising the energy mix we use to power our operations. You can download our detailed environmental data using the link below.
Reducing our impact
Toll roads generally provide faster and more consistent travel times compared to alternate stop-start routes, saving customers time, fuel and GHG emissions.
On average our customers generate 28% less greenhouse gas emissions by using our roads instead of the alternate route.
The graph below shows how travel-time savings translate to less GHG emissions.
Smart road and tunnel design also helps to reduce vehicle emissions. Factors such as the gradient or steepness of the motorway, its alignment and the smoothness of the road’s surface (pavement) can go a long way toward reducing vehicle emissions. For example, NorthConnex was designed with a straighter and flatter gradient to minimise emissions.
Building major infrastructure is one of the most energy and resource-intensive parts of Transurban’s business. One of the ways we minimise the impact is by requiring our projects to achieve an ‘Excellent’ Infrastructure Sustainability rating (IS) as a minimum standard.
The IS rating tool is facilitated by the Infrastructure Sustainability Council (ISC), and benchmarks best practice sustainability standards on infrastructure assets across planning, design, construction, and operation phases.
This has helped reduce GHG emissions by 771,580 tCO2e across nine projects to date.
While our business continues to grow, energy-efficiency improvements—such as optimisation of tunnel ventilation systems and lighting upgrades—are achieving significant savings on individual roads and tunnels.
We have a 10% energy-efficiency savings target from a 2013 baseline, which applies to our 2016 asset base. In FY23 we achieved our target, having delivered 13% in energy-efficiency savings, which reduced our energy consumption by more than 73,000 GJ each year.
Electricity represents 92% of Transurban’s total Scope 1 and 2 energy use, with most used to power our lighting, tunnel ventilation systems and traffic management centres. These efficiencies have come from improvement initiatives such as upgrading to more efficient LED lighting and optimising tunnel ventilation systems in response to updated traffic profiles.
Reducing your emissions
Eco-driving is a driving technique that reduces fuel consumption, emissions and can minimise vehicle wear-and-tear.
We ran an eco-driving trial in Queensland, which involved 400 customers fitting a smart device to their vehicle to monitor efficiency. Information from the smart device encouraged more economical driving and led to a 5.5% reduction in greenhouse gas emissions.

In a survey of over 3,000 people across Victoria, New South Wales and Queensland we found 42% would like to their next car to be an electric vehicle, but high purchase cost, lack of charging infrastructure and concern around how much it would cost to charge were holding them back. Findings were published in the August 2021 edition of our Urban Mobility Trends report.

We gave some of our Australian customers the opportunity to test drive a Nissan Leaf electric vehicle for 10 days to really test its performance and see how an EV could fit into their home, workplace and lifestyle.
