About this episode

The built environment doesn't have an innovation problem. It has a scaling problem. Emily-Rose Garnett and Philippa Birch-Wood of the UK Green Building Council authored the report mapping why sustainable solutions in real estate keep dying in pilot. Alex — who once ran innovation inside a major property firm — recognised every barrier in it. The solutions we need mostly already exist. The problem is systemic, not technical: risk-averse cultures, a certification catch-22 that starves materials innovators, and pilots never designed to scale.
