In 2023, the sustainability guidelines were updated to apply to new developments and extension and renovation projects Group-wide. Requirements for all projects include zero waste to landfill for future operation, 100% of timber with FSC or PEFC certification for both works and the building itself, and divert demolition, strip-out and construction waste from landfill with at least a 70% waste recovery rate. Requirements for large projects include minimum environmental certification level (BREEAM 'Excellent' for projects in Europe or LEED Gold in the US), feasibility assessment of bio-sourced materials for structural elements, long-term climate risks analysis, and integration of at least 2 circular economy 'concepts' from the Group's Circular Economy Framework. The use of wood in URW's development projects is always studied to both reduce the embodied carbon emission of projects and increase the carbon sinks through the lifetime of the projects. Circular economy solutions can also lead to carbon savings, through material reuse for example.
