Materials are getting harder to source and more closely scrutinised, and infrastructure clients are asking sharper questions about where they come from. This article looks at what resource efficiency means in practice, from smart early decisions to measurable evidence trails, and how project teams can turn good intentions into real outcomes.

Infrastructure development carries a significant environmental footprint, driven largely by materials that are resource-intensive, carbon-intensive and usually locked in early on a project. Sustainable procurement builds environmental, social and governance considerations into every procurement decision, what to procure and who to procure it from, and its benefits go beyond emissions reduction, improving project efficiency and reducing ownership and operation costs over time.

Through collaboration with industry partners, universities and major infrastructure clients, we've developed an interactive tool built with a series of assumptions allowing users to calculate a Material Circularity Indicator (MCI) with readily available infrastructure design and delivery inputs.
