Many developments and projects will require detailed assessments of site-based impacts, for example as part of an Environmental Impact Assessment (EIA). Defining the AoI of a project is an important step towards realising the extent of site-based impacts. There are several sector standards and regulatory mechanisms that provide guidance on how to calculate AoIs, for example, the International Finance Corporation’s Performance Standard 6 (IFC PS6) and the ‘Good Practice for the Collection of Biodiversity Baseline Data’ guidance.
