Transurban has a long-standing commitment to sustainability which is consistent with our purpose – to strengthen communities through transport.

We recognise that to provide long term value for investors and meet the needs of each of our stakeholder groups, we must deliver more than just financial returns. We set high standards for our performance across environmental, social and governance issues and transparent disclosure of our sustainability performance.

Actions we're taking

United Nations’ Sustainable Development Goals alignment 

Transurban’s Sustainability Strategy is aligned with the United Nations’ Sustainable Development Goals (SDGs). 

We have identified nine SDGs that are most relevant to our business, and we report on how we are contributing to these global goals.

Learn more about our approach.

The international Support the Goals initiative has given our SDG approach a 5-Star rating. We’re also working with our biggest suppliers, advocating for their participation in the SDGs.

Task Force on Climate-related Financial Disclosures (TCFD)

Climate change is already influencing the way we identify, measure and manage climate-related risks. We need to prepare our assets to better adapt to potential future climate scenarios.

With 22 roads operating across Australia and North America, it is undeniable that the impact of climate change will affect the way we run our business in the future – including because of substantial physical changes to our climate. Changes across technology, market and reputation will be required as our world transitions to a low-carbon economy.

Our latest Climate Change Disclosure is available in our FY23 Corporate Report (p39)

Addressing the gender pay gap

We report annually to the Workplace Gender Equality Agency (WGEA) on key workforce gender equality indicators. Data we report includes gender representation, pay metrics and workforce management statistics. WGEA, in turn, reports on applicable Australian companies’ performance across these metrics.

Gender pay gap reporting: statement of context

From 2024, WGEA has begun publishing gender pay gap (GPG) data of relevant employers. Our targeted focus on advancing gender equality is demonstrated in our GPG performance. 

We recognise that the biggest drivers of our gender pay gap are caused by the gender mix in our workforce, across levels and types of work. Our diversity and inclusion objectives and ongoing focus on gender equity aim to address this by improving gender balance across our organisation.

We will continue working to address the gender pay gap and advance gender equality in our organisation and industry.

Global and national benchmarking performance

We have consistently ranked in Equileap’s top-10 Australian and top-20 global companies for multiple years. We are currently the no.1 global and Australian company on gender equality performance in Equileap’s annual ranking program (2024).  

Transurban reports to WGEA annually and in accordance with the Workplace Gender Equality Act 2012. We also apply for the Employer of Choice for Gender Equality citation, which we were awarded for the 2021–2023 period, our tenth consecutive year. See all current citation holders here.

Modern Slavery Statement

Modern slavery is a serious and complex issue that requires a long-term and coordinated response. As such, we have joined like-minded industry partners to adopt a united approach to addressing this issue. Our latest Modern Slavery Statement outlines how we work to identify, manage and mitigate the specific risks of modern slavery in our operations and supply chains.

While we did not identify any instances of modern slavery in our operations or supply chains in this financial year, we will remain vigilant in monitoring and addressing these risks and continue to deepen the engagement with our supply chain partners.

Social performance

Transurban’s purpose is to strengthen communities through transport. Our customers, local communities and employees are all important stakeholders in this purpose.

Read more below about how we work with residents near our roads, build community partnerships, improve customer service and how we are promoting a diverse and flexible working environment.

Customer advocacy

We have around 10.5 million customers in Australia and North America, and we’re always working to improve our customers’ experiences, both on and off the road. To succeed in this mission, we need to understand what our customers value and need from us.

One way we track our customer support performance is through our Voice of Customer program that checks in with customers and collects feedback at key points in their journeys. Learn more about our customer approach.

Net Promoter Score (NPS)

We measure our performance via a Net Promoter Score (NPS). Our Voice of Customer program checks in with customers during key interactions with us, including asking them: How likely is it that you would recommend Linkt to a friend or colleague? Customers rate us out of 10, with scores of nine and 10 demonstrating customer advocacy and loyalty. These ratings inform our NPS.
