Global concerns about environmental degradation have emerged since the 1970s, reflected in conferences, meetings, reports, among others, carried out by the United Nations (UN), which international agreements arise in favor of preserving the world's biodiversity. Perceptions on Sustainable Urban Development encompass the conceptualizations of evolution, social awareness and environmental conservation. In order to measure global Sustainable Development, the Agenda 30 published by the UN comes into force, with 169 goals, broken down into 254 indicators, which they do not assess municipal sustainability. The objective of this study is to propose a system of indicators that allows the analysis of urban sustainability in the face of the social, political-institutional and environmental dimensions of the municipalities of the Metropolitan Mesoregion of Belém. The Urban Sustainable Indicators Matrix (MASU) was designed using that data collection carried out through internet sites, at no cost to the researcher. To validate this proposal, two methodologies were applied: the Likert Scalar method (adapted), and the Principal Component Analysis (PCA) method, that analyzes results are divided into two chapters. The results obtained by the Likert Scale method (adapted) point to sustainability by the indicators of the Social Dimension and unsustainability by the indicators of the Environmental and Political-Institutional Dimensions, consecutively, highlighting the municipalities of Belém and Santa Bárbara do Pará as sustainable, and the municipalities of Marituba, Inhangapi and Castanhal as unsustainable. The sustainability achieved by the municipalities infers cities with Sustainable Development, although this sustainability is associated by the relative analysis of the data sample. While the application of the PCA method showed sustainability in by the indicators of the Social Dimension and unsustainability by the indicators of the Political-Institutional Dimension, highlighting the municipalities with Sustainable Development being Barcarena, Santa Barbara do Pará, Inhangapi and Santa Isabel do Pará as sustainable, due to the criteria of signs and similarities, measured through the data of the Principal Components (CPs). That way, MASU highlighted realistic results, showing (un)favorable indicators for local sustainability, providing subsidies to public management to solve specific problems and develop effective public policies to meet the needs of the population and achieve Sustainable Urban Development.
