The Infrastructure Sustainability Council (ISC) has published its annual impact report, detailing the progress made in promoting sustainability across the sector in 2024.
The 2024 Impact Report highlights the achievements that ISC and its ecosystem of member organisations and stakeholders have delivered during the year, including efforts to influence policy and regulations that shape the sector, ISC’s membership, training and supplier programs and the IS Ratings. It also profiles the expertise, influence and reach of the wider ISC ecosystem.
This year’s report outlines outcomes that certified projects have delivered. 25 certified As Built projects contributed 144,000 tonnes to the total of 1,353,000 million tonnes of avoided lifecycle materials emissions and 1,447,000 tonnes to the total of 23,546,000 tonnes of lifecycle operating emissions avoided since 2018. In both FY23 and FY24, 100 per cent of ISC certified projects made use of innovative materials.
Additionally, the report provides case studies showcasing key sustainability initiatives and developments, including new innovative materials and initiatives across major infrastructure projects.
For example, the report highlights the Victorian Government’s ecologiQ program which has been instrumental in advancing the use of recycled materials in transport infrastructure.
Meanwhile, at Rosehill (HRT) Ashfield plant, Downer is pioneering efforts to apply innovative technology to produce high performance road pavement materials that incorporate a substantial component of repurposed material and has several Australian firsts to its name. The new Ammann RAH100 High Recycled Technology (HRT) plant can produce asphalt comprised of up to 100 per cent recycled asphalt pavement. The asphalt plant is energy efficient, has stringent and effective emission controls that exceed the highest European standards, is completely automated to ensure a high quality of product, and can use significantly less raw materials in the production process.
Developments from key industry players including InfraBuild, ecologiQ and the Office of Major Transport Infrastructure Delivery in Western Australia were also highlighted.
Steel manufacturer InfraBuild launched its SENSE 600®, a high strength reinforcing steel made from 100 per cent scrap steel that delivers up to a 39 per cent reduction in embodied carbon compared to traditional 500N steel. This innovative material not only reduces carbon emissions but also optimises the amount of raw material used. With certifications like GECA and ISv2.1, SENSE 600® supports sustainability goals and aligns with modern infrastructure projects’ demands for responsible material usage.
