The Group's 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.
