The book provides comparative information about the materialization of the 2030 Agenda in urban policy in ten countries located in Europe and Latin America. The Declaration of Quito is the starting point for the implementation of SDGs into public policies in urban areas. However, there are fewer efforts to understand the impact that the 2030 Agenda and, specifically, the instruments developed for its application in cities. The information of each country is presented in relation to two aspects: the construction of a public policy style in each country and the results and impacts on urban public policies implemented in specific cities within the national frameworks. The first means the emergence of a public policy framework and its materialization in public policy instruments. In this regard, the book raises the following questions: To what extent have the SDGs come to generate a common framework for cities in the countries? And how Urban SDGs are translated to national urban policies? The second, results and impacts at the local level, is related to two aspects: a) substantive: the goals of the policy and b) procedural: management aspects related to the policy design, governance, and institutional capacity building.
