As a major transport infrastructure project with ambitious sustainability targets, METRONET’s Morley–Ellenbrook Line required a coordinated approach to carbon management, materials assessment and ratings performance across multiple project phases and disciplines.

Lately, I’ve been noticing a shift in how sustainability is being practised. Not a sudden change, but a gradual narrowing. Increasingly, sustainability is being defined by what can be measured, verified, and disclosed. What can stand up to audit. What fits within financial reporting frameworks. This has brought rigour, and that matters. But it also raises a question: What happens when sustainability is reduced to what can be audited?
