Materials passports are essential for fostering a circular economy in the built environment. The UKGBC emphasises the need for a shift in thinking, integrating circular principles throughout the building lifecycle. 

These passports digitally store key data on construction materials, enabling recovery and reuse. They provide crucial insights into material end-of-life options, promoting sustainability and waste reduction. 

The UKGBC outlines four key components: basic information (e.g., identifiers, safety, and warranty details), circular economy information (e.g., composition, lifespan), sustainability information (e.g., environmental impact, toxicity), and product-specific details (e.g., certifications, maintenance).
