The 2030 Agenda defined 17 Sustainable Development Goals (SDGs) divided into 169 targets, applicable everywhere and based on the “No one left behind” principle. Goals and indicators to measure the achievement of the 2030 Agenda have to be localized. The paper presents the Italian current evolution of the territorialization of the SDGs, starting from the global level up to the local one, and wonders if the implementation of the 2030 Agenda takes concrete form with the quantitative monitoring of the SDGs at the local level (municipalities and not only capitals). A comparison among indicators proposed at different levels is set by using an ad hoc comparative reading grid. The analysis highlights that, in Italy, the principle barriers in the territorialization of the SDGs are the lack of data open sources, the proposal of new not adequately validated metrics by institutional/non-institutional subjects and the progressive loss of relationship with Global indicator framework and targets of the 2030 Agenda. The strategies needed to reach sustainable development are obviously site-specific, but we need to maintain common metrics in measuring performances in relation to the 2030 Agenda. In the Global indicator framework for the Sustainable Development Goals and targets of the 2030 Agenda for Sustainable Development, it is possible to find indicators suitable to measure performances at the local level—albeit in a smaller numbers—but in Italy, there is no awareness about this. Italy is completely losing both the opportunity to compare the results of the effort performed by the Municipalities in a rigorous way and the possibility to use strong metrics to support decision-makers’ policies for the future.
