Australia has ambitious targets towards a net-zero future, with systems in place to monitor and regulate scope one emissions across all sectors. However, this scope one framework for the management of carbon emissions does not create supply chain accountability for sustainable procurement and use of assets, leaving the responsibility and risk of scope one emissions on the supply side of the supply chain. This paper reviews carbon intensity across the cement and concrete supply chain alongside the national and international policy context towards achieving net-zero targets. Financial levers including capital market drivers towards ESG values and pricing carbon into demand side transactions are considered to propose a framework for supply chain scope three accountability. Achieving scope three accountability at a national level would drive an asset longevity agenda, encouraging and incentivising lifecycle sustainability. This will lead to innovative new solutions, along with a reduction in new build and encouragement to reuse and repropose.
