Material circularity has become a key focus for infrastructure, driven by growing policy, procurement and sustainability expectations. The direction is clear: circularity is becoming an expectation across major projects. Yet despite this momentum, many organisations still struggle to measure and demonstrate circularity in a consistent, defensible way.

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?
