The Voluntary Local Review (VLR) is an analysis of the Sustainable Development Goals (SDGs) for a specific local context. It is a very important monitoring tool for their implementation at city or regional level. The process of SDGs localization that starts with the Voluntary Local Review allows local authorities to identify their own priorities and territorial specificities. When it combines a careful analysis of indicators with a participatory process that involves citizen and local stakeholders and a coherence analysis of existing policies as a basis for planning and policy design it also becomes a strategic planning tool. “Localization” is the process of taking into account national, subnational and local contexts in the achievement of SDGs, from the setting of goals and targets, to determining the means of implementation and using indicators to measure and monitor progress.”
