This month, we asked the industry’s decision-makers, What’s next when it comes to decarbonising the infrastructure and transport sectors?
Duncan Elliott, Chief Executive Officer – Major Road Projects Victoria
North East Link has become the first infrastructure project in Australia to receive the internationally recognised PAS2080 certification – a global standard that focuses on the management of carbon emissions in infrastructure projects. This standard has assisted us in making tangible reductions in the emissions associated with the design development and ultimately operation of the North East Link. Some of the measures that have been implemented across the project include ensuring 100 per cent renewable electricity is used during construction, supplementing concrete with low carbon recycled materials, and committing to net zero emissions in the operation and maintenance of North East Link.
Sarah Bachmann, Chief Executive Officer – National Precast Concrete Association Australia
Precast concrete structures offer long-term environmental benefits that extend well beyond construction. Over their lifespan, precast structures naturally reabsorb carbon dioxide through a process known as carbonation, helping offset a portion of the emissions from production. Their high thermal mass also contributes to energy efficiency by regulating indoor temperatures, reducing reliance on heating and cooling systems. The industry is further advancing sustainability through the increased use of supplementary cementitious materials such as recycled slag and flyash, which lower embodied carbon. Together, these features make precast concrete a smart, sustainable choice for resilient, energy-efficient buildings and infrastructure across Australia.
Tanja Conner, Chief Executive Officer – AustStab
The next frontier in decarbonising the infrastructure and transport sectors lies in scaling up circular practices, low-carbon materials, and smarter asset management. For the pavement recycling and stabilisation industry, this means increasing the use of reclaimed materials, adopting alternative binders with lower embodied carbon, and embedding lifecycle carbon assessments into every project. In-situ stabilisation offers a proven, immediate pathway to cut emissions by reducing haulage, material use, and construction time. Coupled with data-driven design and performance monitoring, these innovations can deliver resilient, low-emission road networks – helping the sector meet sustainability targets without compromising on safety or performance.
