Road infrastructure’s role in global emissions
Almost every city in the world has significant road infrastructure, and this infrastructure is integral to how cities’ residents, workforces and goods and services get around. In Australia, we rely on roads to deliver almost all the food we eat, for example, and governments regularly invest in building new roads to ensure cities stay productive and liveable even as city populations increase. Governments also partner with private industry (including us) to deliver this essential infrastructure.
Building and operating transport infrastructure generates greenhouse gases (GHG); the main cause of the global heating that’s changing our climate. These emissions are generated in part through the manufacture, transportation and installation of materials used to build new roads, tunnels and bridges. Operating and maintaining existing roads also generates GHG: lighting; tunnel ventilation; and pavement (road surface) works all use energy and materials. And most vehicles travelling on roads also generate emissions.
As an owner and operator of toll-roads in Australia and North America, we have a key role to play in leading our industry, adopting and advocating for innovative sustainable practices and low- and zero-emission technology and design solutions. Our roads are designed and built to support free-flowing traffic, which helps minimise the amount of greenhouse gases emitted from vehicles. For example, travel on our roads generates, on average, 27% less emissions than the alternate routes: delivering more efficient roads sooner will help reduce road-travel-related emissions.

Joining a global effort
Meeting the Sustainable Development Goals
The United Nations’ 17 Sustainable Development Goals (SDGs) establish a path to peace and prosperity for people and the planet, both now and in the future. These 17 goals are an urgent call for all governments, industries, groups and individuals to take both immediate and long-term action on critical social, environmental and economic issues.
Our sustainability strategy is aligned with nine SDGs most relevant to our operations, as shown. These goals inform our overall approach to sustainability.
Setting industry-leading standards
We participate in (and are affiliated with) multiple global benchmarking and asset sustainability rating programs. We are rated among the world’s best across many of these leading performance measures.

Our sustainability journey
Our purpose is to strengthen communities through transport
We’ve been monitoring and measuring our sustainability performance formally since 2006, when we produced our first sustainability report. Since then we’ve been implementing an expansive program of sustainability initiatives—all focused on generating benefits for people, the planet, the places we operate and our partnerships. These have been aligned with the United Nations’ Sustainable Development Goals since 2019.
All our activities support our purpose—to strengthen communities through Transport—and are designed to address the needs of our stakeholders. Here’s some of what we’ve been up to since we formalised our sustainability efforts in 2006.
