Construction Waste Diversion Rate is a key ESG metric in property development finance UK, reflecting the percentage of construction and demolition materials diverted from landfill through recycling, reuse or energy recovery. High diversion rates indicate strong environmental management and compliance with sustainability targets, reducing project risk and supporting regulatory obligations. It is calculated as diverted waste divided by total construction waste multiplied by 100. Developers and lenders increasingly monitor this rate to assess sustainability performance, cost efficiency in material management, and alignment with environmental policies across residential, commercial, or mixed-use property developments in the UK.


This sits beneath Sustainable Materials & Waste Management, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside % of Materials from Sustainable Sources, as both are closely related measures used to assess similar aspects of performance or risk.
