The Group material impacts related to pollution have been identified as pollution due to the operations (existing shopping centres) of URW and pollution due to the construction activities of URW. It includes the pollution of air linked to carbon monoxide and fine particles emitted by buildings construction and also, for the buildings in operation, through the visitors' transportation. It also covers the pollution of water and soil throughout the value chain linked to waste deposits, leakage and spills of hazardous products. For those identified pollution sources, URW has set specific policies to mitigate the negative impacts related to those pollutions. The Considerate construction charter aims to mitigate pollution of air, water, soil, fauna, and flora for all major development projects throughout the Group. The Health, Safety ("H&S") and security management policy aims to prevent and limit any pollution within URW operations.
