To fight against the biodiversity loss and to take advantage of ecosystem services that nature can offer, urban planners integrate green spaces in urban projects. However to assess green spaces, attention is generally paid to local biodiversity (i.e. “in situ”)which concerns the plot on which buildings are constructed. The biodiversity impacted outside the construction site (i.e. “ex situ”)which concerns the extraction of materials, transportation and waste, is rarely associated to the project assessment.
