As part of its Better Places roadmap, the Group developed its Group biodiversity strategy in 2020 in collaboration with external experts. A complete study of the impacts and dependencies of the Group against biodiversity was also led in order to focus the Group strategy on appropriate actions. The results of this study identified impacts such as land artificialisation, degradation & fragmentation, degradation of habitats from material production, water consumption, wood and other bio-based material consumption, all greenhouse gases emissions, plant protection (phytosanitary) products, light pollution, single-use plastics used by tenants and visitors, and vegetation choice and maintenance. Dependencies include attractiveness (biophilia), climate regulation (trees cooling down space, vegetal areas reducing "urban heat islands", mitigating extreme weather events), risk mitigations (non-artificialised spaces absorbing rainwater), and resources supply (materials for construction, resources for tenants). These commitments are detailed in the following sections.
