We introduce a novel approach to assessing the exposure of Italian manufacturing companies to flood and landslide risks. This methodology takes into account the geographical distribution of secondary sites and the number of employees. The risk assessment is based on the hazard maps released by the Italian Institute for Environmental Protection and Research (ISPRA) through the portal 'Idrogeo'.
Approximately 35% of manufacturing companies are potentially at risk of flooding or landslide, although the extent of this risk varies. The most significant risk is flooding, which affects 29% of manufacturing workers. The likelihood of a company being exposed increases with the number of establishments. However, a greater geographic dispersion of firms' sites can also mitigate the potential impact of an adverse event, as it reduces the proportion of employees in at-risk areas.
