Due to the unsustainable impacts of urbanisation, including theconsumption of natural resources and peripheral population density,urban sustainability has the potential to support diverse environmental andsocial functions in urban environment. Cities need comprehensive plans tomeet the United Nations Sustainable Development Goals andneighbourhood-level assessment is necessary to ensure the viability of thisprogress. An indicator-based assessment could suggest a path towardssustainability and, at the same time, encourage the development ofassessment tools. To provide arguments for the construction of anevaluation framework, this study investigated the opinions of experts andcitizens regarding urban sustainability issues. These opinions served as thebasis for a principal component analysis to identify the main sustainabilitycomponents, covering the synergies between the objectives of foursustainability dimensions. The five components identified included accessto amenities, mobility and cultural connectivity; education and urbaninfrastructure; diversity of use and housing; open spaces and urbandrainage. The extracted set identifies potential indicators that support thedevelopment of policies, which will promote changes in the Brazilian urbancontext, benefitting neighbourhood sustainability.
