The map presents the geometries of the concluded procedures of regional competence regarding the environmental impact assessment (VIA), a tool for taking into account within the decision-making processes any repercussions on the environment deriving from the construction of works and plants. In particular, the paper presents the national and regional VIA projects, the PAURs (Single Regional Authorization Procedure) and the verifications of subjectability to the VIA (former verification/screening). The 1:25000 scale is to be understood as a maximum: localization is in fact practiced at different scales. The updating of the levels is dynamic on the basis of what has been digitized by the proposers through the front-office applications for the presentation of the activation requests and/or by the Environmental Impact Assessment and Sustainable Development Office of the Liguria Region. - Coverage: Entire Regional Territory - Origin: Localization on Regional Technical Maps - Year: 2023
